What materials do you use for CNC 3D printer parts?

We primarily use 6061-T6 and 7075-T6 aluminum alloys, as well as 304 and 316 stainless steel. These materials offer excellent strength, corrosion resistance, and machinability for 3D printer applications.

What tolerance can you achieve with CNC machining?

Our standard tolerance is ±0.02mm (ISO 2768-m), but we can achieve precision tolerances as tight as ±0.01mm (ISO 2768-f) for critical applications. For specialized projects, we can hold even tighter tolerances upon request.

Are aluminum parts better than plastic parts for 3D printers?

Yes, aluminum parts offer significant advantages including higher strength, better heat dissipation, improved precision, and longer service life. They are especially beneficial for high-performance and industrial 3D printing applications.

How much does a custom CNC part cost?

The cost depends on several factors including material complexity, size, quantity, and tolerance requirements. We provide competitive pricing and offer volume discounts. Contact us with your specific requirements for a detailed quote.

What file formats do you accept for custom parts?

We accept all major CAD file formats including STL, STEP, IGES, SolidWorks (SLDPRT), AutoCAD (DWG/DXF), and CATIA. For best results, we recommend providing STEP or IGES files for maximum compatibility.

What is the typical lead time for custom parts?

Our standard lead time is 7-15 days for most projects. Rush orders can be completed in 3-5 days with expedited processing. For large production runs, lead times may vary depending on volume and complexity.
