Print. Inject. Produce.
The workflow is three steps. Print the mold on the 3D printer you already own. Inject two-part polyurethane with Flovv — it meters Part A and Part B at a precise ratio and mixes them in-line as it dispenses. Produce part after part from the same mold, each one solid, consistent, and ready in minutes-to-hours of cure time instead of a full reprint.
MoldLab makes the mold from your CAD — free
You don't need mold-design experience. Flovv MoldLab takes your part file and generates the matching mold geometry, ready to print — parting line, pour path, and vents handled. Print it, clamp it, cast into it. MoldLab is free for Flovv owners.
Why cast instead of reprinting?
- Batches, not reprints: one printed mold produces copy after copy — your printer is freed up for the next design.
- Solid parts: cast polyurethane is a solid, uniform material — no infill, no layer-by-layer weak direction.
- Material range: rigid, flexible, and foaming polyurethanes from one machine — pick the hardness the job needs.
- No cups and scales: Flovv meters and mixes for you, with no separate degassing step for most casts.
What Flovv is — and is not
Flovv is a low-pressure two-part liquid casting system, similar to RIM-style dispensing. It is not a 3D printer and not a thermoplastic injection molding machine — it doesn't melt pellets. It works alongside your printer: the printer makes the tool, Flovv makes the parts.
What you need to start
- Any 3D printer that can print your mold (FDM or resin)
- A Flovv and a two-part material kit — rigid, flexible, or foam
- Your CAD file — MoldLab turns it into the printable mold
Flovv is made in America and ships from Austin, TX — in-stock orders typically ship within 1 business day.
