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.
| Our Capabilities | Industrial SLA |
|---|---|
| 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 | Fine detailed, high aesthetic and accurate to CAD prototypes |
| End-Use Applications | Low-volume, high aesthetic parts. Some functional end-use applications |
| 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.
To achieve better part quality and end results, it is important that you design your part for the process. Learn how to design overhangs. assembly parts and more in our SLA 3D printing design guide.
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.
Finest Detailing
SLA is one of the best 3D printing technologies for creating very accurate and finely detailed parts.
Rapid Turnaround
Because SLA can create complex and multi-material parts in a single operation, significantly less build time is needed vs. traditional manufacturing.
Smooth Finish
SLA creates parts with an excellent finish which remarkably resembles end use items like injection moulded parts.
Stereolithography or 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.
SLA (or stereolithography) is a plastic 3D printing process that uses light-reactive thermoset materials called “resin.” The process offers a wide range of plastic material options that are often categorized by different material properties, including:
The many advantages of SLA 3D printing have made it a choice for many applications across different industrial sectors for many years, including:
SLA 3D printers use UV lasers to trace out the cross-sections of the model and form a object. This process creates a very high resolution, detailed printout, but it requires a longer print time. On the other hand, FDM (fused deposition modeling) creates parts additively using a filament. The process results in a lower quality printout, but they can do so faster.
