SLA 3D Printing

Stereolithography uses a UV laser to cure liquid photopolymer resin into parts with exceptional surface finish and dimensional accuracy. It is the preferred technology for master patterns used in vacuum casting, high-detail visual models, and transparent components.

SLA Material 01

Standard Grey

Our most versatile SLA resin — a general-purpose photopolymer with excellent dimensional accuracy and smooth surface finish. Suitable for concept models, presentation prototypes, and master patterns for vacuum casting.

Property	Value
Material resembling	ABS-like
Tensile strength	35–46 MPa
Tensile modulus	2433–2848 MPa
Elongation at break	4.8–7.6%
Impact strength (Izod notched)	28–48 J/m
HDT at 0.45 MPa	60–63°C
Shore D hardness	80–86
Best for	Concept models, presentation prototypes, vacuum casting masters

SLA Material 02

Tough Blu — Black

An engineering resin formulated for high toughness and impact resistance. Notably flexible with 40% elongation at break — significantly less brittle than standard SLA resins.

Property	Value
Material resembling	Nylon-like
Tensile strength (yield)	51 MPa
Young's modulus	1800 MPa
Elongation at break	40% — high toughness
Impact strength (Izod notched)	45 J
HDT at 0.455 MPa	75°C
Shore D hardness	80
Best for	Functional prototypes, jigs, snap-fit parts, impact-tested components

SLA Material 03

Clear

Optically transparent SLA resin that can be post-processed to near-optical clarity. Used for fluidic channels, light guides, lenses, and any application where internal visibility or transparency is required. Simple geometries achieve near-optical clarity; for complex geometries, expect high translucency rather than full transparency.

Property	Value
Material resembling	Acrylic-like
Tensile strength (yield)	39 MPa
Young's modulus	1200 MPa
Elongation at break	6%
Impact strength (Izod notched)	25 J
HDT at 0.455 MPa	75°C
Shore D hardness	82
Transparency	Near-optical clarity with sanding and polishing
Best for	Fluidic devices, light guides, transparent covers, lenses

SLA Material 04

High Temp

High-temperature SLA resin with a significantly elevated heat deflection temperature after UV and thermal post-cure. Suitable for under-bonnet automotive testing, airflow testing, and applications requiring thermal stability beyond standard resins.

Property	Value
Material resembling	High Temperature
Tensile strength (UV+Thermal cure)	85.4 MPa
Tensile modulus (UV+Thermal cure)	4816 MPa
Impact strength (UV+Thermal cure)	71.4 J/m (notched Izod)
HDT at 0.45 MPa (UV+Thermal cure)	165°C
Shore D hardness	75–80
Trade-off	More brittle than standard resins — lower elongation at break
Best for	High-temperature prototypes, airflow testing, under-bonnet automotive
