Six processes. One for every prototype.
Resin for fidelity, nylon for production, metal for performance, FDM for budget — we run the right process for the part, not the only one we happen to own.
SLA (Stereolithography)
Smooth surface, fine detail. Best for visual prototypes and master patterns.
± 0.1 mm · 25 µm layers
MJF (HP Multi-Jet Fusion)
Production-grade nylon. Strong, dense, no support marks on Y/Z surfaces.
± 0.3 mm · 80 µm layers
SLS (Selective Laser Sintering)
Functional nylon parts without supports — complex geometries print free.
± 0.3 mm · 100 µm layers
FDM (Fused Deposition)
Large, cheap, tough thermoplastic parts — ABS, PETG, ASA, Nylon, PEEK.
± 0.5 mm · 100 µm layers
DMLS (Metal Laser Sintering)
Titanium, stainless, AlSi10Mg, Inconel. Dense metal parts from CAD.
± 0.1 mm · 30 µm layers
PolyJet
Multi-material, multi-colour, rigid + soft in one print. Visual models.
± 0.1 mm · 16 µm layersThe full envelope.
Max build envelope
1,000 × 500 × 500 mmLarge FDM platform. SLA up to 500 × 500 × 600; MJF/SLS to 380 × 284 × 380; DMLS to 400 × 400 × 400.
Minimum feature
0.2 mmPolyJet / SLA fine resolution. SLS / MJF 0.5 mm walls; FDM 0.8 mm; DMLS 0.4 mm overhang.
Tightest tolerance
± 0.05 mmPolyJet on small parts. SLA / DMLS ± 0.1 mm; SLS / MJF ± 0.3 mm; FDM ± 0.5 mm.
Surface finish
Ra 1.6 µm (SLA, polished DMLS)As-printed Ra varies by process; bead-blast and vapour-smoothing bring nylon to Ra ≤ 3.2 µm.
Lead time
Same-day SLA prototypesProduction MJF 2–3 days. DMLS 5–7 days including heat treat. Bulk runs 10–14 days.
Inspection
Dimensional report on requestCT-scan part density verification available for DMLS critical features. Material certs on metal jobs.
Materials
40+ engineering gradesResins, nylons (PA11/12, glass-filled), 5 metal alloys, elastomers, high-temp plastics.
Which process fits your material?
The fastest way to pick a 3DP process is to start from what the part must be made of. Below: which families of materials each process can run, at a glance.
How smooth do you need?
The single biggest predictor of surface quality in additive manufacturing is Z-layer thickness. Below: nine grades, drawn to scale, anchored to what you would actually print at that setting.
A curated showcase. Our library runs 40+ deep.
The cards below are our most-requested grades — kept loaded and calibrated for fast turnaround. Specialty resins, custom-pigmented dyes, and medical-grade certifications on request.
Need a material not shown above? Our library is 40+ deep across resins, nylons, metals, and specialty thermoplastics. Send a datasheet and we will load it.
Finished off the bed.
A showcase of our most-requested post-processing steps — eight of 25+ supported across smoothing, colouring, plating, and assembly. Parts ship complete, no DIY required.
IPA wash + UV post-cure on every SLA build and HIP / anneal / solution treat on every DMLS build are included by default — they're prerequisites, not extras. Custom Pantone-matched dye, electrostatic flock, hand-airbrush, and assembly-ready inserts available on request.
CAD to door, in four steps.
The same engineer reviews your file, supervises the build, and signs off on the inspection report — so nothing gets lost between slicer and shipping.

STL is the universal 3DP exchange format; we also accept STEP, 3MF, SOLIDWORKS (.sldprt), OBJ, and IGES.
For colour PolyJet jobs send 3MF or OBJ + texture map. For SLA dental or jewellery work we accept the raw mesh export from your CAD package.
Standard SLA prototypes uploaded before 11 am ET typically build and post-cure the same business day. Critical-path parts ship the next morning. MJF nylon production lots typically run 2–3 working days.
Process-dependent. PolyJet and DMLS hold ± 0.05–0.1 mm on small parts. SLA holds ± 0.1 mm. MJF / SLS hold ± 0.3 mm — typically 0.2 % of nominal dimension. FDM is the loosest at ± 0.5 mm but tunable down to ± 0.2 mm on calibrated rigs.
Yes — every additive process leaves some Z-stepping. SLA at 25 µm is the smoothest as-printed (lines barely visible at arms-length); MJF at 80 µm is matte but felt by fingernail. Vapour-smoothing brings MJF / SLS to glass-smooth; hand-sand + paint hides every line on visual prototypes.
Yes — Formlabs BioMed Clear (USP Class VI, ISO 10993-1 / -5), BioMed White, and BioMed Amber for surgical-guide and dental work. DMLS Ti-6Al-4V is implant-compatible with appropriate post-processing. We coordinate the documentation chain through partner facilities; ask before quoting.
Yes — DMLS in Ti-6Al-4V, SS 316L, AlSi10Mg, Inconel 718, and CoCr. Standard post-processing includes stress-relief anneal, support removal, surface bead-blast, and dimensional inspection. Optical HIP and machining of critical features are available on request.
1,000 × 500 × 500 mm on our largest FDM platform. SLA and MJF cap at ~500 mm in one axis. Larger parts are split into sub-prints and bonded — we recommend sectioning the CAD before quoting so the split lines land on a non-cosmetic surface.
No. We quote single prototypes the same way we quote 5,000-piece MJF nylon runs — the price-per-piece just changes.
Yes — PolyJet supports per-voxel RGB-CMY colour for visual models and demos. MJF nylon is dyeable post-print in black and a small range of colours. SLA resins come in any colour we can pour; send a Pantone target.
Every quote includes a free DFM review. The engineer flags thin walls, unsupported overhangs, trapped resin pockets, and undersized holes before quoting, and suggests changes that reduce cost or improve print success rate.
