FAQ
What is DFM engineering and why do I need it?
DFM (Design for Manufacturing) means optimizing your design so it is easier, faster and cheaper to produce. Applying it early helps you avoid costly errors and redesigns.
What do I need to send to get started?
Sketches, hand drawings, photos, dimensions or reference files are all fine. The more detail you share, the more accurate your design will be.
Which manufacturing methods do you design for?
CNC machining, injection molding, sheet metal fabrication and 3D printing.
Which file formats will I receive?
STEP, STL, IGES and DXF files, plus source files depending on your package.
Do you provide 2D technical drawings?
Yes. I create manufacturing and assembly drawings with dimensions, tolerances and GD&T, ready to send to your manufacturer.
Can you build a functional prototype design and render it?
Yes. I design print ready prototype files and can create photorealistic 3D CAD renders for marketing, pitches and presentations.
