Surface & finishing
SLA surface finish: smooth straight off the printer
Each layer cures from a self-levelling liquid, so surfaces come out close to injection moulding, with layer lines that are almost invisible.

FDM · 0.1 mm layers8–15 µm
SLA · 0.05 mm layers2–4 µm
Injection moulding1–2 µm
Typical surface roughness (Ra). Lower is smoother.

Note: most resins yellow and turn brittle with long UV exposure, and supports can leave small marks on some surfaces. Talk to us before ordering if there are critical surfaces. To check your file for thin walls, small holes and trapped resin, run a DFM review.

Choosing a process
SLA vs. FDM vs. SLS
Not sure SLA is right? Here's the short version. See all processes →
| Best for | Strength | Surface | Cost | |
|---|---|---|---|---|
| SLA | Fine detail, smooth cosmetic parts, clear & specialty resins | Resin-dependent: rigid to rubbery | Smoothest, small support marks | Mid |
| FDM | Large parts, quick jigs, budget prototypes | Good, directional | Visible layer lines | Lowest |
| SLS | Functional end-use parts, snap-fits, complex geometry | High, near-isotropic | Fine matte, no support marks | Best in batches |
FAQ
SLA 3D printing FAQ
How does SLA compare to FDM and SLS?
SLA gives the finest detail and smoothest surfaces of the three, plus the widest choice of specialty materials. FDM is cheaper for large, simple parts but shows layer lines. SLS makes tough nylon parts with no supports and a fine matte texture. Choose SLA when looks, fine features or a specific material property matter most.
Which SLA resin should I use?
Standard Grey for visual models and fit checks. Tough 2000 for stiff, functional parts, Durable for squeezable or low-friction parts and Silicone 40A for soft, rubber-like parts. Clear for light pipes and lenses, High Temp for heat, Castable Wax for jewellery. Not sure? Tell us what the part does and we'll recommend one.
How accurate and smooth are SLA parts?
Most parts hold ±0.15 mm or ±0.3%, whichever is greater, depending on geometry and resin. Layers are 25–100 µm and surfaces are typically Ra 2–4 µm, close to injection moulding. Flag any critical dimensions and we'll review them before printing.
Are SLA parts strong enough for functional use?
Standard resins are stiff but can crack under impact. Tough 2000 adds ABS-like strength and Durable adds impact resistance and flex. For heavy loads or large structural parts, SLS nylon or engineering FDM is usually the better choice.
Will I see support marks?
SLA parts print on small supports that we remove after curing, leaving tiny marks where they touched. We orient each part to keep those marks off cosmetic faces, so tell us which surfaces matter.
Can SLA parts be used outdoors?
Most resins yellow and turn brittle with long UV exposure. For outdoor parts, consider ASA on FDM or SLS nylon.
What affects SLA cost?
Part volume, height (taller builds take longer), resin and finishing. Specialty resins such as Clear, High Temp and Castable cost more than Standard. Pricing is upfront via the instant quote.
How fast can you deliver SLA parts?
Most orders ship in 1–4 business days depending on size and resin, with tracked shipping across Canada or local pickup in Victoria. Rush may be available for urgent projects.
What's the maximum part size?
200 × 125 × 210 mm in-house. Larger parts can be printed in sections and bonded, made through our partner network (up to 1800 × 900 × 600 mm), or moved to large-format FDM.
Can you print biocompatible or dental parts?
Yes, on request, in Formlabs BioMed and Dental resins. BioMed Clear and BioMed Durable are USP Class VI certified; you're responsible for confirming a material fits your regulatory pathway. See our medical & dental capabilities.
