What is 3D printing

Additive manufacturing, layer by layer

3D printing — also called additive manufacturing — builds objects from a digital model by bonding powdered metal, plastic, or similar materials layer by layer. It typically covers SLA, SLS, MJF, and metal SLMS additive processes plus engineering-grade FDM, with resins, nylons, metals, and carbon-fiber composites. Ideal for complex geometry without tooling: the go-to for concept and appearance prototypes, high-precision sampling, and nonstandard small-part customization — freeform surfaces, lattices, and integrated shapes for R&D iteration, appearance checks, functional tests, show samples, and short-run production.

Core capabilities | Engineering-grade 3D printing

Covering industrial 3D printing processes and engineering materials, with automated quoting and DFM review — from prototype validation through functional parts and low-volume production.

  1. 1. Automated 3D file parsing

    Automatically parse mainstream formats such as STEP, IGES, STL, and OBJ. Detect volume, wall thickness, hole diameters, chamfers, surfaces, and complex features to ground process selection, DFM analysis, and cost estimation.

  2. 2. DFM manufacturability review

    Run Design for Manufacturability analysis for 3D printing — minimum wall thickness, overhang angles, support needs, build orientation, and post-process feasibility — then flag risks and suggest structural optimizations for higher yield and consistency.

  3. 3. Multi-process smart quoting

    Match SLA, SLS, MJF, FDM, SLM, and related processes from geometry, material, and quantity, then return comparable price and lead-time ranges so teams can pick the best 3D printing path quickly.

  4. 4. Engineer review + quality control

    Every order gets engineering review of process and parameters, plus standardized in-process QC so dimensional accuracy, strength, and surface quality meet the design intent.

  5. 5. Industrial materials & tolerance assurance

    Choose from industrial-grade 3D printing materials with clear tolerance bands and performance metrics by process — so parts meet assembly, strength, and service-life requirements.

3D printing materials

ABS

Also known as photopolymer resin — typically available in white, black, and yellow. Excellent at fine type, chamfers, and textures with a smooth surface that takes paint and silk-screen well. Ideal for budget-friendly, review-ready appearance prototypes and validation parts.
