What is Stereolithgraphy?

Stereolithography (SLA) is a 3D printing process used to create concept models, cosmetic prototypes, and complex parts with intricate geometries. It’s an additive manufacturing technology that forms parts by curing thermoset resin with a UV laser. A wide selection of materials, extremely high feature resolutions, and quality surface finishes are possible with SLA.

Our SLA 3D printing service

Requirement	Specification
Min. Wall Thickness	0.6mm for unsupported walls, 0.4mm for supported walls on both sides
Layer Height	25 µm to 100µm
Max. Build Size	1400x700x500mm
Dimension Tolerance	±0.2mm (For >100mm, apply 0.15%)

The table below depicts the general tolerances for industrial-grade stereolithography (SLA) services. Stresses during the build, support strategy and other geometry considerations may cause deviation in tolerances and flatness. Improved tolerances may be possible with a manual quote review, after successful completion of a prototype build, and must be approved on a case-by-case basis.

SLA 3D printing finishing options

As-printed

Support structures, if present, will be removed, and support surface nibs will be lightly sanded until smooth, ensuring a high-quality finish.

Vapour polished

Vapour polishing is done to increase the smoothness of the surface.

Custom

You can specify custom finishes such as painting and electroplating. Note that custom finishes require manual review and quoting and may be subject to approval.

SLA 3D Printing Advantages

Surface & Detail: SLA has tolerances of +/-.004” per inch, and resin surface is ideal for post-processing like polishing and painting.
Cost Saving: SLA is one of the cheapest method for rapid prototyping while preserving a good surface quality and accuracy.
Geometry: SLA allows to integrate multiple components as well as thin-walled objects and intricate geometries that traditional method won’t be capable of.
Turnaround: SLA 3D printed parts do not require tooling which reduces the manufacturing lead time from weeks to days, allowing for faster innovation and speed to market.
Material Selection: There’re various material with special properties like toughness, heat resistance, flexibility, which simulates the end products.
Scalable Volume: Multiple, identical parts can be built on a single platform at one time, greatly increasing production efficiency.
