Upload your CAD files
Securely upload your 3D models for engineer-reviewed DFM and quoting. We support STEP, STP, IGS, STL, OBJ, 3MF, and PDF.
Sample RFQ package
Use the sample checklist and documentation examples to decide which drawings, tolerances, finish notes, inspection records, material certificates, and packing evidence should be included before production.
What happens next
Complete RFQs are reviewed within 24 hours. Complex DFM or multi-process quotes may take up to 48 hours.
We receive CAD, 2D drawings, reference photos, and notes through secure upload or NDA-first contact.
Add process, material, finish, quantity, tolerance level, inspection requirement, destination, NDA, and first-article needs.
Inspection documents must be agreed before production because scope can affect cost and lead time.

Prepare a quote that engineering can price accurately
A quote request should capture more than a file upload. DFocus reviews the process route, material, finish, tolerance, quantity, inspection needs, packaging, and delivery destination before returning a practical manufacturing response.
STEP, X_T, STL, DXF, PDF drawings, photos, finish references, and assembly notes make CNC machining, 3D printing, sheet metal, and tooling quotes more reliable.
Material grade, part size, tight tolerances, finish, quantity, shipping destination, and inspection documentation shape the final quote.
Use this route for CNC prototype machining, rapid prototyping China support, plastic prototypes, enclosures, fixtures, and low-volume manufacturing.
The fastest useful response comes from complete files plus one short note explaining the prototype purpose and any critical dimensions.
How to prepare a quote-ready RFQ
Use this page to organize the files, material, finish, quantity, tolerance notes, inspection needs, packaging assumptions, and delivery destination that engineering needs before pricing.
What engineers need to review accurately
A stronger RFQ identifies the functional goal, critical dimensions, appearance requirements, quantity, flexible constraints, and inspection evidence expected before shipment.
RFQ configuration checklist
Fields needed for an engineer-reviewed quote
The upload is only step one. A quote-ready RFQ should define process route, material and grade, quantity, finish, tolerance level, cosmetic requirement, inspection requirement, destination country, deadline, NDA required, first article approval required, and quote type.
If the project is still early, send the closest available files and explain what is not final yet. DFocus can separate a rough process estimate from a production-ready quote, but the buyer should still identify the part purpose, target material, required quantity, cosmetic surfaces, mating parts, and any deadline pressure. That context reduces back-and-forth and makes the first quote more useful. For sensitive projects, note NDA needs, branding limits, export destination, and whether the first shipment is for testing, display, or customer validation. Add revision history if the CAD has already changed, including older material or finish assumptions.
