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. Design rules per process are in the 3D printing design guide; how they compare on price is in the 3D printing cost guide. Compare process routes in 3D printing process selection and check the 3D printing material library before choosing a grade.
SLA (Stereolithography)
Smooth surface, fine detail. Best for visual prototypes and master patterns.
Detail-focused resin workflow
MJF (HP Multi-Jet Fusion)
Production-grade nylon in a powder-bed workflow. Specify surface state, orientation and finishing for the functional faces.
Nylon production workflow
SLS (Selective Laser Sintering)
Functional nylon parts without supports — complex geometries print free.
Support-free nylon workflow
FDM (Fused Deposition)
Large, cheap, tough thermoplastic parts — ABS, PETG, ASA, Nylon, PEEK.
Thermoplastic extrusion workflow
DMLS (Metal Laser Sintering)
Titanium, stainless, AlSi10Mg, Inconel. Dense metal parts from CAD.
Metal powder-bed workflow
PolyJet
Multi-material, multi-colour, rigid + soft in one print. Visual models.
Multi-material resin workflowThe full envelope.
Max build envelope
Quoted by selected processA machine work volume is not automatically the maximum finished part. Geometry, orientation, splitting and post-processing are reviewed with the file.
Minimum feature
Quoted by feature and orientationWalls, holes, unsupported details and enclosed volumes depend on process, material grade, orientation and finishing.
Tightest tolerance
Specified per functional featureCritical fits need a process, material, final condition, datum and inspection method; general process figures do not apply to every geometry.
Surface finish
Defined in the delivered conditionAs-printed texture and any blasting, dyeing, smoothing, coating or machining must be selected for the material and functional faces.
Lead time
Timing confirmed in the quoteQueue, material, build volume, post-processing, inspection and delivery destination determine the schedule.
Inspection
Inspection plan by requirementState the critical features, accepted measurement method and documentation needed with the drawing or quote request.
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.
Layer height is one surface setting.
Layer height influences visible Z stepping, but it does not by itself define surface roughness or the delivered finish. Material, orientation, geometry and post-processing matter too. Below are example settings drawn to scale.
A curated showcase. Our library runs 40+ deep.
The cards below are our most-requested grades — kept loaded and calibrated for the selected workflow. Specialty resins, custom-pigmented dyes and material documentation are reviewed with the exact process and 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.
Cleaning, curing and metal thermal processing depend on the selected material and workflow. Dye, smoothing, paint, coating and inserts are specified separately; confirm compatible material, visible faces and delivered dimensions in the quote.

Answers, on the record.
Engineers wrote these. If yours is not here, emailengineering@fabdigit.com for a discussion of the part requirements.
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.
Availability is confirmed after the file, material, build volume, finishing, inspection and delivery destination are reviewed. Ask for the required delivery date with the CAD; the quote will state the process-specific schedule and any trade-offs.
Accuracy is process-, material-, orientation-, geometry- and post-process-dependent. Identify the functional features, datums, delivered condition and measurement method in the drawing; the selected route can then be reviewed against those requirements. Do not use a general process figure as a guarantee for every part.
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.
Some manufacturer material products have specific biocompatibility or testing documentation for defined workflows. That documentation does not certify a finished part, medical device or implant. Medical or implant suitability requires the exact material, process, post-processing, validation, documentation chain and applicable regulatory review to be assessed for the intended use.
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.
Colour options depend on the selected material and workflow. PolyJet colour, dyeing of compatible nylon and paint are distinct routes; an as-printed material colour does not guarantee a dye or paint match. State the target, visible faces, finish and any approved sample in the quote request.
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.
