Overview

What SLA Resin is good at

SLA cures liquid photopolymer with a laser, layer by layer, and nothing else we offer comes close to it for surface quality or fine detail. Walls down to half a millimetre, crisp lettering, sharp edges and a finish close to injection moulding come straight off the machine. Zbotic industrial 3D printing gives you twelve production resins — general-purpose, high-strength, transparent, low-shrink and one genuinely high-temperature grade — on a build platform large enough for bumper-sized parts.

SLA Resin technical specifications
Layer thickness 0.05–0.10 mm typical; 0.025 mm available for fine cosmetic and jewellery work
Dimensional tolerance ±0.2 mm on features under 100 mm; ±0.3% above 100 mm
Hole tolerance ±0.3 mm
Minimum wall 0.5 mm on small parts, scaling to about 2.0 mm on large flat panels
Maximum part size Up to 780 × 780 × 530 mm on the largest platform; individual resins have their own smaller size and weight ceilings, confirmed at quote
Minimum feature Holes from 1.0 mm; embossed or engraved detail 0.8 mm wide, 0.8 mm deep; drain holes 2.5 mm
Surface finish Smooth and semi-gloss, roughly Ra 1–5 µm as printed; dyeing and spray finishing available
Materials

Materials you can order

Every grade below is quotable today. If you are not sure which one fits, put your file through the quote page and ask us — we would rather help you pick than have a part come back.

Matte white general-purpose resin — high hardness and strength (heat deflection ~59 °C)
Deep black resin — high toughness, good dimensional stability (~65 °C)
Grey resin — polishes to a very smooth touch, low shrinkage (~59 °C)
Black resin for batch work — low shrinkage, high stability (~58 °C)
Light-green low-shrink resin — good yellowing resistance (~56 °C)
Natural-white stable resin — for moisture-exposed models (~56 °C)
Transparent and translucent resin — light pipes, fluid visualisation (~53 °C)
Faint-yellow high-strength resin — best all-round mechanical grade (~72 °C)
High-temperature resin — heat deflection ~101 °C, for tooling and warm environments
High-strength white resin — industrial models and structural mockups (~60 °C)
High-precision black resin — for humid environments (~46 °C)
Mixed-batch economy resin — random colour, sample quantities only
Applications

What people print with SLA Resin

A cross-section of the work that lands in this lane.

Master patterns for silicone moulding, vacuum casting and investment casting
Jewellery masters and fine ornamental work
Dental and medical models and surgical planning aids
Fit-check and assembly-verification parts where 0.2 mm matters
Miniatures, figurines and highly detailed scale models
Transparent parts — light guides, fluid-flow channels, lens mockups
Cosmetic prototypes for client and investor presentation
The honest view

Where it wins, and where it does not

Every process trades something away. Read the right-hand column before you commit a design — it is the part most services leave out.

Advantages

Why this lane gets picked

  • Best surface finish and finest detail of any lane we offer — parts look moulded, not printed
  • Tightest tolerance of the industrial lanes: ±0.2 mm under 100 mm
  • Genuinely transparent and translucent options, which no powder process can match
  • Very large build platform, so big single-piece parts avoid bonding seams
  • Thin walls down to 0.5 mm are realistic on small parts
  • Dyeing and spray finishing available, so parts can arrive presentation-ready

Limitations to design around

Told straight, before you order

  • Heat resistance is the real limitation. Most of these resins have a heat-deflection temperature between 46 °C and 72 °C, so parts will soften in a parked car, near a motor, or in direct Indian summer sun. Only the high-temperature grade reaches about 101 °C — pick it deliberately, or move to nylon.
  • Cured resin is stiffer and more brittle than nylon. It chips and snaps rather than bending, so snap-fits, living hinges and drop-tested parts belong in MJF or SLS.
  • Ultraviolet light continues to work on resin after printing. Parts left in sunlight yellow and grow more brittle over months.
  • Supports are required. Down-facing surfaces carry small witness marks unless you specify additional finishing.
  • Resin keeps shrinking slightly for several days after printing — expect drift on the order of 0.15–0.2 mm on larger dimensions.
  • Large thin unsupported panels can bow. Add ribs, or thicken to the 2 mm end of the wall range.
  • Heat-deflection figures quoted here are measured at low load (0.45 MPa). A part under real mechanical stress will deform well below its stated number.

FAQ

SLA Resin questions, answered

How fine can SLA go?
Layers of 0.05–0.10 mm are typical and 0.025 mm is available for fine cosmetic and jewellery work. Walls go down to 0.5 mm on small parts, holes from 1.0 mm, and embossed or engraved detail from 0.8 mm wide by 0.8 mm deep. Tolerance is ±0.2 mm on features under 100 mm.
Can SLA parts take heat?
Only within limits, and this is the single most important thing to get right. Most of the twelve resins have a heat-deflection temperature between 46 °C and 72 °C — they will soften in a parked car, near a motor, or in direct Indian summer sun. Exactly one grade reaches about 101 °C. Pick it deliberately, or move to nylon. All of those figures are measured at low load (0.45 MPa); under real mechanical stress a part deforms well below its stated number.
Are resin parts brittle?
Cured resin is stiffer and more brittle than nylon — it chips and snaps rather than bending. Snap-fits, living hinges and anything that gets dropped belong in MJF or SLS nylon instead.
Can I get transparent parts?
Yes. A transparent and translucent resin (heat deflection around 53 °C) is available for light pipes, fluid visualisation and lens mockups. No powder process can match it.
How big can an SLA part be?
Up to 780 × 780 × 530 mm on the largest platform, so big single-piece parts avoid bonding seams. Individual resins have their own smaller size and weight ceilings, which we confirm at quote.
Will the part change size after printing?
Slightly. Resin keeps shrinking for several days after printing — expect drift on the order of 0.15–0.2 mm on larger dimensions. Ultraviolet light also keeps working on resin, so parts left in sunlight yellow and grow more brittle over months.
How long does an SLA order take?
15–20 days, produced on Zbotic's industrial line and delivered pan-India.
