Fluidraft is microfluidic CAD with a validated 0D/1D flow solver, design-for-manufacture checks and fab-ready export. We do not fabricate anything, and we never will. You do. That makes us complementary rather than competitive, and it suggests an arrangement that costs neither of us anything.
Your process rules, inside the tool
We add your shop to FABRIX as a supported process profile: your minimum feature size, minimum gap, depth range, aspect-ratio limit, corner radius, tolerances and materials, exactly as you publish them. A designer working in Fluidraft selects your process, and the tool checks their geometry against your rules while they are still drawing. When they export, the manufacturing package carries the layer table, the stated depths, the process assumptions and a manifest. In return, when somebody comes to us needing a chip made in your material, we send them to you.
| You give | We give |
|---|---|
| Your published design rules — the same ones you already send customers as a PDF. One page, one conversation. | Your process named in the product, in front of every designer choosing how to make their chip. |
| A named contact for referred enquiries. | Referrals: design-only enquiries that reach us, routed to you by material and geography. |
| Optional: a mention in one newsletter, if and when you think it is worth your readers' time. | Free seats for your own design and applications engineers, for as long as the profile is live. |
Why this is worth your time
The quotes that cost you most are the ones needing three rounds of email before they are makeable — and those rounds are unbillable. A design that arrives already checked against your own rules skips most of them.
- The customer arrives further along. They know their depth, they know which dimension is critical, and the flow behaviour has been sanity-checked. They are ready to talk about tooling rather than about physics.
- It costs you nothing to try. The rules are public, the profile takes us an afternoon to build, and if it produces nothing in six months we remove it and part on good terms.
What we are careful about
We also take no commission on your work, and we do not want exclusivity. Several shops can hold profiles for the same material; the designer chooses. We are not trying to become a marketplace — we sell design software, and your success in fabrication is simply what makes that software worth buying.
Four steps, no contract
- You send your design-rule sheet, or point us at where it is published.
- We build the profile and send it back for you to check. Nothing goes live until you have read it and agreed it is accurate.
- It ships in the next release, with your shop named.
- We agree a contact address for referrals, and leave it running.
Nothing here is exclusive or binding. If at any point you want the profile removed, say so and it goes in the next release.
