SLM (selective laser melting) fully melts metal powder layer by layer to produce dense, strong metal parts. Choose SLM for complex metal geometries such as internal channels and lightweight lattice structures.
A range of materials is available, including Photopolymer Resin, Nylon (PA12 / PA11), TPU / Flexible Materials, ABS / ASA / PC (FDM), Metals (Aluminum / Stainless / Titanium). The best choice depends on strength, appearance, operating environment, and budget. Our engineers can help you select the right one during the quote review.
Achievable tolerances depend on material, part size, and geometry. Typical values are listed on this page, and tighter tolerances can often be held on critical features. Share your drawing and we will confirm during the DFM review.
Yes. We support everything from a single prototype to ongoing production programs, so you can scale without changing supplier.
Cost depends on material, part size and complexity, quantity, tolerances, and finishing. Upload your CAD model and drawing to receive a quote, and our engineers can suggest design changes that reduce cost.
We accept common 3D CAD and 2D drawing formats, including STEP, STP, IGES, STL, SLDPRT, X_T, DXF, DWG, and PDF. If your format is not listed, please contact us.
Lead time depends on process, quantity, and finishing. Prototypes can often ship within a few business days, and we ship worldwide. Contact us with your requirements for a lead-time estimate.
SLM adds material to build complex shapes with little waste, while CNC removes material from a block and offers tighter tolerances and better surface finish. They are often combined: print, then machine critical features.
