3D printing service · Industrial SLA

Large format SLA, for industrial parts

Precision, scale and performance. Our UnionTech stereolithography fleet produces functional prototypes, tooling and end-use parts with outstanding surface finish, in single pieces up to 800 mm across.

What SLA is

Stereolithography is a form of additive manufacturing that uses vat photopolymerisation. A UV laser cures liquid polymer resin layer by layer, exactly where it is needed.

Unlike FDM, which melts filament, or SLS, which sinters powder, the liquid resin solidifies very precisely. The result is smooth surfaces, tight tolerances and clean geometry straight off the build platform.

Why industrial SLA

  1. 01

    Surface finish and detail

    Ultra-smooth surfaces and fine features for visual models or precision prototypes, with little post-processing.

  2. 02

    Dimensional accuracy

    Tight tolerances and stable, repeatable parts for functional testing or fit checks.

  3. 03

    Complex geometry

    Intricate internal features, thin walls and forms other processes struggle with.

  4. 04

    Large single pieces

    Big components in one piece, with fewer joins and consistent quality across the build.

Why we run UnionTech

UnionTech industrial SLA machines are our machine of choice, for their vertical wall consistency and accuracy. Large-volume UnionTech machines print big, seamless parts with high accuracy, so full-scale prototypes, jigs, tooling and foundry moulds need fewer joins.

They give an excellent surface finish and crisp detail across large areas, so parts need less sanding. They are cost-efficient at scale, which means a better price per part than many large format alternatives.
