Stereolithography (SLA) or resin 3D printing is great for concept models, rapid prototypes, master patterns, snap fit assemblies and form and fit testing.
We use Formlabs machinery at our SLA 3D printing service. These top of the range industrial 3D printers are designed for controlled, consistent production of end-use parts. Using 3D resin printing materials, these machines use the latest in environment control to ensure maximum dimensional stability (± 0.20 mm below 100mm / ± 0.30 % above 100mm).
Combined with our knowledge and advanced finishing techniques, we use the Form series machines to produce the best quality SLA 3D prints on the market. See our material properties below or download a data sheet.
Below is a list of our 3D resin printing materials offered at our SLA 3D printing service. To instantly compare material prices, upload your parts to our online platform
Parts are produced to a dimensional accuracy of ± 0.1% with a lower limit of ± 0.075 mm
Parts are printed solid by default, excellent for retaining liquids & ensuring maximum strength
Surfaces are smooth, due to minimal layer heights. Great for simulating moulded parts
Identical & consistent material properties in all given directions at every given point (x, y, z axis)
Features as small as 0.1mm can be successfully printed using SLA, perfect for small parts
Depending on the size, geometry, and material, resin 3D printing can be cost-effective. However, our costing model works off material volume; the higher this value, the more expensive your part will be! Check out our blog post on tips to help you reduce your part costs.
The answer is no. Resins are toxic, and substances may migrate from SLA parts, no matter what the level of post-processing (UV + thermal). Some resins are certified as biocompatible; however, this in no way means that they’re food safe. Some food contact safe coatings are available; however, we don’t recommend using these as the coating may interact with the resin or degrade over time.
SLA (Stereolithography) or resin 3D printing is the process in where liquid photopolymer resin is cured using a light source, in this instance, a small laser. Using pre-determined geometry, it’s able to accurately produce incredibly small & detailed parts.
We have several different material options available at SGD. Some of these resins are created with functionality in mind, and we have materials that simulate the rigidity and stiffness of PEEK, ABS & PolyPropylene.
Resin in its raw form is toxic, however, all parts produced at our 3D printing service are professionally post-processed. All resin printed parts are washed in an IPA bath and UV + thermally cured as specified by our material supplier.
