Resources FAQ

How do I use these resources to get a faster quote?

Start with the file prep and quoting checklists, then send a PDF + STEP/DXF (as applicable) with material, quantity, timeline, and any critical tolerances called out. The clearer the intent, the fewer revisions and follow-up questions.

Which guides should I read first?

If you’re new to the process, start with the pillar guides (CNC machining, precision machining, materials, and laser cutting). If you’re deciding between methods, start with the comparison articles (laser vs CNC, sheet metal vs CNC).

What information do you need for a fabrication quote?

The fastest quotes come from a drawing or CAD export plus a few key details: material (or environment/use-case if undecided), thickness/size, quantity, timeline, finish requirements, and any critical-to-function dimensions or tolerances. If a part interfaces with existing equipment, include notes or reference dimensions that drive fit.
