What Is FlowXD? A Guide to Flow Waterjet Dynamic XD
FlowXD is a search term often used for Flow Waterjet’s advanced XD cutting technology. The official product name is Dynamic Waterjet® XD. It is built for shops that need more than simple flat cutting. The system adds controlled multi-axis motion for bevels, angled edges, and complex 3D work.
The key idea is simple. A normal waterjet points straight down. Dynamic XD can move the cutting head through several axes while software controls the jet angle. Flow says the system also corrects two common waterjet errors: stream lag and taper. That mix of motion and correction is what makes the technology useful for precision parts.
What Is FlowXD?
FlowXD refers to Flow’s Dynamic Waterjet XD cutting approach. It combines 5-axis cutting with the company’s Dynamic Waterjet technology. That allows the head to cut flat parts, bevels, and 3D shapes while compensating for jet behavior during the cut.
This matters because abrasive water does not behave like a rigid drill bit. The stream can trail behind the commanded path. It can also create taper through thick material. Dynamic XD uses automatic head movement to reduce those errors instead of forcing the operator to fix every angle by hand.
How Dynamic Waterjet XD Works
A waterjet first creates very high water pressure. The water passes through a tiny orifice and becomes a very fast stream. For hard materials, garnet abrasive is added to increase cutting power. Flow describes waterjet as a cold cutting process based on erosion rather than heat.
The XD system adds motion control to that basic process. The cutting head can tilt as the machine follows a programmed path. The control system changes the angle to manage taper, stream lag, bevel geometry, and 3D features. That gives the machine more freedom than a standard vertical head.
Why Five-Axis Motion Matters
Five-axis motion gives a fabricator more control over the edge of a part. Instead of cutting only at 90 degrees to the sheet, the head can approach material from changing angles.
Flow lists wrist articulation of up to 89 degrees of motion for Dynamic Waterjet XD, along with 12 inches, or 305 mm, of vertical travel.
That range can support detailed bevels and complex profiles that would be hard to produce with a fixed head. The technology can therefore reduce the gap between rough cutting and a part that is ready for fit-up, welding, or another production step.
More Than a Flat-Part Tool
The value is not simply that the head tilts. The system also applies compensation while it moves. That is important when the cut angle changes across the same part.
Active Tolerance Control Explained
One of the main features behind Dynamic Waterjet is Active Tolerance Control. Flow says the system uses mathematical cutting models to compensate for stream lag and taper.
Stream lag happens when the bottom of the jet trails behind the top as the head moves. Taper occurs when the cut width changes from one face of the material to the other. Both can hurt edge accuracy.
With Dynamic XD, these corrections happen through controlled head movement. That reduces the need to slow every cut just to hold better geometry.
Bevel Cutting With FlowXD
Bevel cutting is one of the clearest reasons to use an XD head. A bevel may be needed for weld preparation, edge design, assembly clearance, or part fit.
Flow says its Dynamic XD technology can perform full flat-stock bevel cutting, with the head able to articulate for angled cuts. The company also notes that better edge quality can reduce or remove some secondary processing.
For a production shop, that can be more useful than raw cutting speed alone. If FlowXD produces a bevel close to the final shape, operators may spend less time grinding, machining, or reworking the edge.
3D Cutting and Complex Shapes
Some parts need more than a straight bevel. They may have changing angles, compound surfaces, or features that move through more than one plane.
Dynamic Waterjet XD was designed for this type of work. Flow describes it as a high-precision 3D cutting system that combines 3D capability with Dynamic Waterjet control.
FlowXD can also work with a rotary indexer on supported systems. Flow states that this setup can extend the process to 6-axis cutting for tube, pipe, and bar stock. The rotary unit adds controlled rotation while the XD head handles angled waterjet motion.
Where This Can Help
It can suit aerospace parts, tube work, prototypes, and other jobs where compound cuts are common.
Materials the System Can Cut
Waterjet is known for broad material support. Flow says standard abrasive waterjet systems can cut metals, stone, glass, composites, and other hard materials. Pure waterjet can also handle softer materials.
The cold-cutting process is a major advantage. It does not create the heat-affected zone associated with many thermal cutting methods. That can matter when heat could change hardness, distort an edge, discolor a surface, or damage a laminate.
The system keeps that waterjet benefit while adding angled and 3D motion. Material choice still affects speed, abrasive use, edge finish, and final tolerance.
Accuracy, Kerf, and Edge Quality
Precision is one of the main selling points of advanced waterjet equipment. Flow says Dynamic Waterjet and Dynamic XD can cut detailed parts to accuracies as tight as ±0.001 inch in suitable applications. The same company page states that a typical waterjet kerf is about 0.030 to 0.040 inch.
Those figures are not a guarantee for every job. Material, thickness, speed, setup, and part geometry all matter.
Still, FlowXD is built to control the factors that often reduce accuracy in angled waterjet cutting. For buyers, a real test cut is more useful than relying on a headline tolerance alone.
Software and Operator Control
A multi-axis machine can sound difficult to program. Flow pairs Dynamic Waterjet XD with FlowXpert Infinity software. The company lists it as the software platform for the XD cutting head.
The broader Dynamic Waterjet system is designed so that head articulation and compensation can happen behind the scenes. Flow says operators do not need to manually program every compensation angle for standard Dynamic cutting.
For XD users, software is central to the process. Good toolpaths must account for cut direction, angle, lead-ins, material, thickness, and collision risks. Automation helps, but clean setup still matters.
Productivity and Secondary Processing
A faster cut is only valuable if the part still meets its print. This is where Dynamic Waterjet technology aims to improve the full production cycle.
Flow says its standard Dynamic Waterjet can cut parts two to four times faster than conventional flat-stock waterjet systems in applicable work. That claim is for Dynamic Waterjet generally, not a blanket speed promise for every XD job.
The bigger FlowXD gain may come after cutting. Accurate bevels, narrow kerfs, and near-net shapes can reduce grinding or machining. Nesting parts more tightly can also lower scrap. Flow highlights both reduced secondary work and raw-material savings as benefits of precision and bevel waterjet cutting.
FlowXD vs Standard Waterjet Cutting
A standard waterjet keeps the stream perpendicular to the workpiece. It is simple, flexible, and useful for a huge range of 2D cutting jobs. Flow says its standard head can cut hard materials and material over 10 inches thick, although practical tolerance changes with thickness and job conditions.
FlowXD serves a different need. It is aimed at parts that require active angle control, precision bevels, taper correction, or 3D geometry.
A shop cutting basic flat brackets may not need that extra motion. A shop making weld-prep edges, complex profiles, or high-value precision parts may gain much more from it.
When FlowXD Makes Sense for a Shop
The best fit is work where part geometry creates cost after the first cut. Think about jobs that need repeated bevel grinding, extra machining, careful heat control, or complex fixtures.
FlowXD may be worth considering when five-axis cutting can remove one or more of those steps. It can also make sense when a business wants one cutting platform for several materials instead of separate thermal and mechanical processes.
Before buying, compare cycle time, abrasive use, pump needs, maintenance, software, training, and finishing time. Ask for test cuts using your own material and CAD files. That gives a far better picture of production value.
Final Thoughts
FlowXD is best understood as shorthand for Flow Dynamic Waterjet XD, a multi-axis waterjet technology made for accurate bevel and 3D cutting. Its main strength is not one single feature. It combines cold cutting, controlled head articulation, taper correction, stream-lag compensation, and software-driven motion in one process.
For simple 2D work, a standard waterjet may be enough. But for complex angles and precision parts, Dynamic XD offers a wider cutting envelope and the chance to reduce follow-up work. The right decision depends on the parts you make, the tolerances you hold, and the cost of every step after the cut.

Twitch Affiliate Requirements in 2026: What Changed and How to Track Your Progress
Twitch lowered the bar for its Affiliate programme in 2026, and many older guides still quote the previous numbers. If you are trying to unlock subscriptions, Bits payouts and the other Affiliate perks, it is worth knowing exactly which goals you need to hit, how Twitch measures them, and how to check your progress without guessing.
The current Affiliate goals
Twitch’s “Path to Affiliate” achievement now asks for four things within the same 30-day window:
- 25 followers
- 4 hours of streaming (240 minutes in total)
- Streams on 4 different days
- An average of 3 viewers on 4 of those days
The old version asked for 50 followers, 500 minutes (about 8 hours) and 7 separate stream days. If a tutorial still lists those figures, it was written before the update.
How the “3 average viewers” rule really works
This is the goal that confuses most new streamers. Twitch does not look at one big average across the whole month. It looks at each stream day separately: a day counts when your average concurrent viewers for that day reaches 3. You need four such days in the last 30 days, and days below 3 simply don’t count. They do not pull the others down.
A few details matter in practice:
- Days are counted in GMT. Twitch’s achievement tracker uses GMT without daylight-saving adjustments, while your analytics dashboard shows your local time zone. A late-night stream in the Americas can land on the next day in Twitch’s count.
- Chatbots don’t count as viewers.
- The average is per day, not per peak. Hitting 10 viewers for five minutes during a raid doesn’t help much if you spend three hours at one viewer.
Because of this, a short, focused stream at a time your community can actually join often does more for the requirement than a long stream in an empty time slot.
Checking your progress with real numbers
The achievement page in your Creator Dashboard shows whether each goal is complete, but it doesn’t explain how close a given day is to the threshold. To plan ahead, you can feed your own stream data into a Twitch average viewers calculator. Enter the length of each stream and the viewers you had, and it shows the average per day and which days already qualify. This is useful when you are deciding whether one more stream this week could complete the goal.
What about Partner?
Partner is the next step and is considerably harder. The current “Path to Partner” achievement asks for 6 streams on 6 unique days with an average of at least 75 viewers, in two consecutive 30-day windows. A broadcast below 75 average viewers simply doesn’t count towards the six. Even when you meet the numbers, Partner is an application: Twitch reviews it, and exceptions are possible for creators who are growing quickly or who bring a large audience from another platform.
A realistic 30-day plan
- Pick a fixed schedule. Two or three set days per week, at the same hour, makes it easier for the same people to return. Consistency helps the per-day average more than random long sessions.
- Stream for 60 to 90 minutes. Shorter streams make it easier to keep your average above 3 for the whole session.
- Bring your existing audience. Friends, Discord members and followers from TikTok or YouTube Shorts are usually your first regular viewers.
- Collaborate. Co-streams and raids with streamers of a similar size bring real viewers who already enjoy your category.
- Check your days weekly. Once three qualifying days are complete, plan the fourth stream for your strongest time slot.
The zero-viewer start is the hardest part for almost every new channel, and a whole market of growth services has formed around it. On sites like ViewerWorks, for example, streamers can buy Twitch viewers or followers for their broadcasts. Whatever route you choose, the viewers who return week after week are the ones who came for your content.
After you qualify
Twitch sends the Affiliate invitation automatically, but it can take up to 48 hours to appear. Before you accept, make sure your account has two-factor authentication enabled and a verified email address, because both are needed for onboarding and payouts. Once you are in, it helps to estimate what subscriptions and Bits might bring in at your size. A free Twitch earnings calculator gives a quick, realistic picture of subscriptions and Bits before you plan any upgrades to your setup.
For the official wording of each goal, Twitch keeps an up-to-date description on its achievements help page.

What Kind of Business Can You Launch With a Laser Cutter in Australia?
A laser cutter lets one person turn timber, acrylic and leather into finished products without a factory. In Australia, that translates into a handful of well-proven micro-business models built around customisation, local style and small-batch work. Here are five that makers and small business owners regularly talk about, followed by guidance on margins, machines and where to sell.
1. Personalised Australiana and Home Décor
Native timber wall signs, nursery name plaques, entry signage and layered wooden artwork are consistent sellers. There is steady local demand for custom timber and for rustic or boho styling in Australian homes, and layered designs are hard to copy by hand, which helps you avoid pure price competition.
Tip: Build a small collection around a theme, such as native florals, coastal towns or nursery names, so customers can buy a matching set.
2. Wedding and Event Décor
Acrylic or timber welcome signs, custom table numbers, place cards and cake toppers sell all year round. Rustic and boho weddings in particular lean on laser-cut details, and couples will pay extra for something made to match their colours and venue.
Tip: Offer ready-to-order packages (signage, table numbers, place cards) so couples can decide quickly and you can batch production.
3. B2B Custom Business Signage
Acrylic company logo signs, QR-code display stands for cafés, and office or door plaques are a good route to repeat customers. Local small and medium businesses tend to have higher average order values than individual buyers, and they come back when they open a new location or change their branding.
Tip: Visit local cafés, clinics, and offices with a sample. A physical piece of work in a business owner’s hand is the best sales pitch you have.
4. Engraved Drinkware and Gifts
Custom tumblers, wine glasses, leather hat patches and cork coasters are popular for markets and online gifting. Unit costs are low, production is quick and margins are strong. One detail to get right: a CO2 laser can’t engrave bare stainless steel directly. Stainless tumblers are usually coated or marked using a fibre laser or a marking compound, so choose products that suit your machine.
5. Custom Prototyping and Short-Run Fabrication
Architectural models, custom packaging inserts, leather goods and small components cut to order fill a niche for independent designers and makers who need a small batch without paying industrial setup fees. This work builds relationships with architects, product designers and artists, which can lead to repeat business.
Choosing the Right Machine for the Business
The laser type should follow the product.
- CO2 lasers are the best all-rounder for timber, acrylic, paper, leather and glass etching. They’re the natural choice for wall art and signage.
- Fibre lasers are specialised for direct metal engraving, such as jewellery, metal tags and some tumblers, but can’t cut wood.
- Diode lasers are an entry-level option for light engraving and softer materials, but they’re generally limited for dense acrylic or glass.
For most of the business ideas above, a CO2 machine covers the widest range of products.
Profitability: What to Expect
Community discussions and local market guides commonly cite gross margins of 60 to 85 per cent on individual custom laser-cut or engraved products. Once you account for platform fees such as Etsy or Shopify, packaging, material waste and marketing, whole businesses typically net around 15 to 30 per cent. Treat these as ballpark figures rather than guarantees. Your own margins will depend on pricing, material costs, how much time each piece takes and how efficiently you batch your work.
Where to Sell
Many Australian makers start on Etsy, Facebook Marketplace, weekend craft and design markets, or a dedicated Shopify store. Markets are useful for testing products and meeting customers face to face. Online stores scale better once you know what sells.
A Machine That Suits Most of These Businesses
If you’re looking for a single machine to cover signage, wedding décor, gifts, and prototypes, the OMTech Polar Lite 55W desktop CO2 laser engraver and cutter is a strong candidate. It’s currently listed at A3,299,orA3,299,orA3,609 with LightBurn included.
Features that matter for the business models above:
- Camera positioning. A built-in camera shows your material on screen so you can place designs precisely and reduce waste.
- Autofocus and integrated water cooling. Less setup time and no external chiller to find room for.
- A 500 × 300 mm working area with pass-through. Large enough for wall signs, wedding signage, and multiple smaller items in one run.
- Closed, enclosed design. Safer for home and small studio use, and easier to keep dust and smoke under control with proper extraction.
It works with LightBurn, so you can use standard vector files from design tools. Check the product page for the current specifications and what’s included, and plan for ventilation and a suitable workspace.
Before You Launch
- Choose a niche. A focused offer, such as nursery décor or café signage, usually sells better than a general range.
- Test your pricing. Include materials, machine time, finishing, packaging, and your own labour.
- Check regulations. Registering an ABN and understanding GST and any insurance or council requirements for working from home are worth doing early. For specifics, speak to an accountant or the relevant authority.
- Start small. Make a sample range, photograph it well, and test it at a market or on one online channel before scaling.
A Simple First-Month Plan
In week one, choose a niche and design a starter range of five to ten products. In week two, make samples and photograph them in natural light. In week three, list the products online or book a market stall, and approach three local businesses with samples. In week four, review what sold, what people asked for, and what took too long to make, then refine the range. This kind of small, measured launch costs little and tells you more than months of planning.
Final Thoughts
A laser cutter gives you the ability to make products people value precisely because they are personal. Decide whether your strength is homeware, weddings, business signage, gifts, or prototyping; choose a machine that suits your materials, and start with a small range you can make well. Margins in this space can be healthy, but they come from careful pricing, steady marketing, and a product that stands out.

Sending a Code Is Only One Step
Planning Phone Verification for Saudi Mobile Numbers
Before a small business adds phone verification, it needs to decide who is responsible for every step behind the screen. A text message can arrive while a customer still cannot finish registering. An accepted code can be followed by an application error. A useful product plan gives each stage an owner and explains what the customer can do if it fails.
Imagine a fictional workshop booking service in Riyadh. Customers choose a session and enter a Saudi mobile number. Before confirming the reservation, the service asks them to enter a one-time password, or OTP, sent by SMS. The business wants evidence of access to the contact number supplied for the booking.
Decide what the code should establish
Successful validation provides evidence that someone could obtain the code sent to that number at that moment. It does not, by itself, establish the applicant’s legal identity, nationality or entitlement to another person’s bookings.
NIST’s digital authentication guidance describes authentication in terms of control of authenticators and classifies telephone-network authentication as restricted within its authentication framework. It also explains that this kind of code entry is not phishing-resistant. A small business should therefore consider what an accepted code will unlock. Checking a booking contact and recovering access to an existing account are different decisions.
For the fictional service, define the immediate outcome narrowly: the number has passed the required check for this booking attempt. The reservation still needs to be saved and confirmed by the application.
Agree where provider responsibilities begin and end
Ask what the selected product and integration actually handle. A delivery service may transmit a code generated elsewhere. A managed verification service may also generate codes, check submissions and enforce some limits. An authentication platform may sit between the application and the SMS provider. The allocation must be explicit.
For the delivery step, Tawked documents SMS OTP delivery to Saudi mobile numbers only, making it one possible component to assess for that number scope. The application team should still establish which responsibilities belong to each part of its chosen setup.
Ask the developer to describe that setup in plain language. Who decides whether a code is valid? Who prevents repeated guesses? What information comes back when sending fails? These answers matter more to planning than a general promise that a service “supports OTP.”
Use a responsibility checklist
For each row, name a person in the business or development team who will confirm the arrangement. Record provider responsibilities from the relevant documentation. Outsourcing a function still leaves someone responsible for checking that it works with the application.
| Step | Application responsibility | Provider scope to confirm |
| Collect the number | Explain the purpose, accept supported formats and allow correction. | Supported destinations and number-format rules. |
| Request a code | Make an authorized server request tied to the pending action; protect credentials. | Acceptance responses, errors and safe retry behaviour. |
| Deliver the SMS | Handle reported results and unavailable delivery information. | Delivery arrangements, status meanings and available reports. |
| Validate the code | Associate the result with the correct number, request and intended action. | Who generates and checks codes, including expiry and single use. |
| Limit attempts | Address abuse across the application and define recovery. | Limits on sends, resends and incorrect entries; what resets them. |
| Explain the result | Display accurate messages and available next actions. | Error details and timing information supplied to the application. |
| Complete the booking | Save the reservation and confirm it only after success. | How a verification result is returned to the application. |
| Handle support | Own customer enquiries and arrange safe escalation. | Support routes and diagnostic references available to the team. |
Keep delivery and completion separate
In the fictional service, an accepted send request means only that the request reached the provider’s documented acceptance stage. Where delivery reports are available, the team must understand their meaning. A reported delivery does not establish that the intended customer read the SMS or submitted its code. Missing delivery information should remain an unknown, rather than being labelled a definite failure.
Code validation is a separate event. The application should advance only on a trusted server decision for the relevant request. An on-screen success message or a delivery status cannot substitute for that decision.
Even after a valid code, saving the reservation can fail. The service should distinguish “number verified” from “booking confirmed” and provide a way to continue without accidentally creating duplicate reservations. This is application behaviour that needs an owner, regardless of who delivered the message.
Set limits that repeated requests cannot bypass
OWASP’s guidance on handling one-time passwords recommends limited validity, single use, strict attempt limits and keeping OTP values out of logs. Ask the developer to show where these controls are enforced, whether in the application’s server or a managed service.
Sending limits and incorrect-code limits address different problems. The first can help control unwanted messages and spending; the second constrains guessing. A fresh code should not create an unlimited new guessing opportunity. NIST’s out-of-band authentication model specifically requires failed-attempt counts to survive the generation of another secret.
Confirm what a resend does to earlier codes and how limits apply across new requests. Choose expiry and retry settings with the developer, considering the action’s risk, the provider’s supported controls and a workable recovery path. There is no need to borrow a countdown or attempt count from an unrelated service.
A visible resend timer should reflect the actual rule enforced by the server. It explains when another request becomes available; it does not enforce that restriction by itself. Code expiry and resend availability should also be treated as separate states.
Give customers an understandable next step
Show the Saudi-number requirement before asking for a code, and let the customer correct the number. If the service offers Arabic and English screens, review the instructions and number display in both languages.
For this fictional application, “Please enter a Saudi mobile number” could explain an unsupported destination. If the server confirms expiry, “This code has expired. Request a new code” gives a next step, provided another request is allowed. When the cause is unknown, “We could not complete verification” is more accurate than blaming the mobile network.
Make the action fit the message. A temporary restriction needs useful waiting information when that is known. A failed booking save needs guidance about the reservation. Avoid wording that unnecessarily reveals whether someone else has an account.
These examples concern application screens. The SMS content available from the selected delivery service is a separate matter and must follow that service’s documented options.
Prepare support before the first customer gets stuck
Give support staff a way to distinguish a sending problem, an unsuccessful code check and a reservation that did not save. Useful diagnostic records can include stage timestamps, a non-secret request reference and an outcome category. Keep OTP values, credentials and unnecessary personal information out of those records; decide who can access them and how long they are needed.
A support enquiry can ask when the problem occurred and what message appeared. Staff should not ask customers to share their OTP or a screenshot containing it. Losing access to a number also needs a defined recovery process; a caller’s request should not become an informal way to bypass verification.
Review accepted requests, delivery outcomes where available, successful validations and confirmed reservations separately. A gap between successful validations and saved reservations is a reason to inspect the application flow. It is not proof of a particular fault.
Before launch, ask the developer and support owner to walk through an incorrect number, a delayed code, repeated resend clicks, an exhausted attempt limit and a booking-save failure. For each situation, agree what the customer sees, what is recorded and who investigates. Launch approval should cover the successful reservation and the response when one of its steps fails.
