How 3D printing works

A digital model is sliced into layers. Each layer is cured, fused, or extruded, then the next layer is added until the part is complete.

  1. Read the file

    Upload STEP, STL, or 3MF. We read walls, volume, and support risk from the file.

  2. Match a process

    Compare processes and materials on one quote — resin, nylon, or metal.

  3. Set finish and qty

    Choose finish (sand, dye, vapor smooth, machine) and quantity before you order.

  4. Print and ship

    We print, inspect, and ship. Delivery dates stay on the quote line.

What is 3D printing

3D printing — additive manufacturing — builds a physical part from a CAD or mesh file by placing thin layers of photopolymer, thermoplastic, or metal powder. The printer only adds material where the model needs it, so lattices, internal channels, and one-off shapes do not require dedicated tooling.

On AIHFABS the same upload can price resin, nylon, and metal processes. You choose the process for cosmetics, strength, or heat, then add dye, vapor smoothing, or machining on the quote instead of sending a second RFQ.

Main 3D printing technologies

Four processes cover most buyer searches: FDM, SLS, SLA, and MJF. Metal SLM, DLP, and LCD sit in the capabilities list below.

What this 3D printing service is good at — and where it is not

Use the plus column to decide if additive is the right first path. Use the limits column to know when CNC or molding will win later.

Strengths

  • Geometry without fixtures Internal ducts, lattices, and consolidated assemblies that would need many CNC setups.
  • Same-week prototypes Most plastic jobs leave the shop in hours to a few days after the file is approved.
  • Print only the lot you need Keep the model in a library and reprint when the revision changes — no obsolete stock.
  • Light, application-specific materials Resins for detail, nylons for clips and ducts, TPU for flex, metals when heat or load demands it.
  • One step from file to part No soft tooling for 1–200 pieces. Design edits stay in the CAD, not in a mold shop.
  • Less subtractive scrap Material goes into the part and supports, not a leftover billet. Powder beds recycle unused powder.

Limits

  • Not every stock is printable Only resins, selected nylons, TPU, and a short metal list. Food-contact and some alloys need another process.
  • Build envelope A part larger than the chamber is split and joined. That adds time and a bond line.
  • Finishing is usually required Supports, powder cake, and layer texture need clean-up before a cosmetic or sealing face is ready.
  • Unit cost stays flatter Unlike injection molding, printing does not drop sharply at thousands of pieces.
  • Layered structure FDM in particular is anisotropic. Load paths should follow the layers or move to SLS, MJF, or CNC.
  • Tolerance is process-specific Typical plastic holds about ±0.2–0.3 mm. Critical bores still want machining after print.

3D printing FAQ

Which 3D printing process should I choose?

Match the job: SLA, DLP, or LCD for smooth visuals; SLS or MJF for durable nylon; FDM for inexpensive fixtures; SLM for metal. Each child page lists materials and limits.

How accurate is online 3D printing?

Typical plastic parts hold about ±0.2–0.3 mm; metal SLM is tighter after machining. Exact capability is on each process page and confirmed on the quote.

Can I mix 3D printing and CNC?

Yes. Many orders print a near-net shape, then machine critical faces. Start here, then open SLM or the CNC landing if you need subtractive work.

What files do you need?

STEP is best for metals and CNC-adjacent jobs; STL or 3MF is fine for plastics. One upload prices every process you select.
