Stereolithography or SLA is one of the earliest and the most versatile 3D printing technologies. The parts are accurate to CAD and have a good surface finish which can be easily improved with post process finishing.
Stereolithography is fast, cost-effective and offers one of the widest ranges of material options, making it a good option for prototypes and low volume production.
| Maximum Build Size | 800 x 800 x 550 mm (31.5″ x 31.5″ x 21.6″) |
|---|---|
| Lead Time | 2-3 days |
| Resolution | ± 0.2mm |
| Prototyping Applications | Detailed, aesthetic visual prototypes (especially of injection moulded parts). |
| End-Use Applications | Low-volume, aesthetic, non-functional end use parts. |
| Applicable Materials | Colour | Description | |
|---|---|---|---|
| Sanding | All | – | Sanding SLA printed parts is often the best way of smoothing edges, removing blemishes, and getting rid of any leftover support marks. |
| Spray Painting | All | Black, Pantone/RAL colours | Spray painting is a quick way to colour parts. It can also reach areas that cannot be reached with a brush. |
| Plating | ABS | Metallic | Plating is method of adding a thin layer of metal of the outer layer of a material. It is used to harden, decorate and improve wearability of parts. |
SLA 3D printing builds parts one layer at a time using a highly accurate UV laser to solidify one layer of photosensitive resin, which makes the parts accurate and in good surface. The parts need to be built with support structures which are removed during post process.

Material Selection
HLH offers a vast material selection with a range of properties, as well as the ability to print multiple materials and simulate overmoulds.
Complex Geometries
Creates complex shapes with a high degree of precision that would otherwise be impossible to build via traditional manufacturing processes.
Rapid Turnaround
Because SLA can create complex and multi-material parts in a single operation, significantly less build time is needed vs. traditional manufacturing.
Precision
We use the latest generation of SLA technologies to meet tolerances of +/- 0.004” or +/- 0.001” per inch, whichever is greater, and offer both normal and high resolution prints
SLA 3D printing is the most common resin 3D printing process. It has become very popular over the years due to its ability to produce highly accurate and watertight prototypes and end-use parts in a range of materials with fine features and smooth surfaces.
Plastic is the most commonly used material in SLA 3D printing predominantly Poly Lactic Acid (PLA) and Acrylonitrile Butadiene Styrene (ABS). SLA offers a wide range of plastic material options.
The advantages of SLA 3D printing have made it a choice for many applications across different industrial sectors, including the automotive, consumer goods, medical and even jewellery industry.
