Choosing the Right 3D Printing Process

Each additive process has different strengths in detail, strength, material choice, and cost. Use the table as a starting point.
Comparison Factor SLA SLS / MJF FDM Metal (SLM)
Best For Fine detail and smooth surfaces Functional nylon parts Low-cost concept and large parts Strong, complex metal parts
Typical Materials Photopolymer resins Nylon powders ABS, PC, PLA and similar Aluminum, stainless steel, titanium
Surface Finish Very smooth Slightly grainy Visible layer lines Matte, usually post-processed
Typical Applications Visual models, masters Housings, clips, low-volume parts Fixtures, concept models Aerospace, medical, tooling
From Digital Model to Metal Part

From Digital Model to Metal Part

Metal printing removes tooling lead time and supports rapid iteration. We review orientation and supports early to avoid distortion and cost surprises.

I think the relationship between the buyers and definitely between me the Mastars it's like a family relationship and this is why we are so happy to produce in Mastars and this is why we came for 15 years. By the way, now we came with a new product that we come to Master to produce for the new year.

Metal 3D Printing Service FAQs

  • What is Metal 3D Printing and when should I choose it?

    Metal 3D printing builds metal parts layer by layer from powder, enabling geometries that are difficult or impossible to machine. Choose it for complex, lightweight, or consolidated metal components.

  • What materials can be used for Metal 3D Printing?

    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.

  • What tolerances can Metal 3D Printing achieve?

    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.

  • Can you support both prototype and production Metal 3D Printing?

    Yes. We support everything from a single prototype to ongoing production programs, so you can scale without changing supplier.

  • How much does Metal 3D Printing cost?

    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.

  • What file formats do you accept for Metal 3D Printing quotes?

    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.

  • How quickly can you deliver Metal 3D Printing parts worldwide?

    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.

  • Which metals can you print?

    Common options include aluminum, stainless steel, and titanium alloys. Exact alloys available are confirmed during project review.
