ADDITIVE MANUFACTURING FOR YOUR NEXT DECISION

Build Confidence Before Your Next Investment

Use the prototype to answer a specific question about fit, function or appearance.

  • Check assembly interfaces before committing to tooling.
  • Explore complex geometry and accessible internal channels.
  • Iterate your design without changing a production mold.
  • Compare a printed part with CNC machining or injection molding.
  • Define the material and tests needed for your intended use.

What to Send for Your 3D Printing Quote

  • STEP / STL / 3MF and controlled drawing
  • Quantity, units and drawing revision
  • Your application and material requirements
  • Critical dimensions and inspection scope
  • Surface finish and assembly needs
  • Target delivery date and destination

Frequently Asked Questions

What files should I send for a 3D printing quote?

Send STEP, STL or 3MF files with units, drawing revision, quantities, intended use, material requirements and finish. Include controlled 2D dimensions for critical features and your delivery destination.

Which 3D printing process is best for my part?

Start with what the part must prove. Review SLA for detailed resin prototypes, SLS or MJF for functional polymer geometry, and metal printing for suitable complex metal parts. The final choice depends on your geometry, material and test requirements.

What lead time and minimum quantity should I expect?

Timing and quantity depend on the process, material, build size, finishing and inspection. Share your target date and sample or batch demand so the quotation can confirm a practical schedule.

Can you print functional or production parts?

Discuss the intended loads, environment, service life and acceptance criteria. A printed prototype does not automatically validate an end-use part. Agree the material, validation and inspection requirements for your program.

Can you machine, finish or assemble printed parts?

Review critical bores, datums, threads, inserts and cosmetic surfaces alongside the build. Confirm material compatibility and any finishing allowance before production.

What tolerances can you achieve?

Achievable tolerances depend on size, geometry, process, orientation and post-processing. Mark your critical features and measurement methods. Some interfaces may require secondary machining.

Can I request material records and inspection reports?

Include the records, report format and inspection characteristics in your RFQ. Availability and documentation scope are agreed before the build.

When should I move from printing to CNC or molding?

Compare material performance, design stability, quantity, tooling investment and total delivered cost. Review the route again after prototype testing and as repeat demand becomes clearer.
