×A thin layer of liquid polymer is spread over the printer platform, ensuring a consistent thickness. A UV laser then draws the outlines of the model onto the resin. As the resin is UV sensitive, the areas touched by the laser are instantly cured and hardened. The areas untouched by the laser remain liquid. The model is then lowered a fraction so that this process can be repeated and a new layer added, until the full model is complete. Any remaining liquid polymer can then be drained away and reused for future models. The finished print must then be finished off, any support structures removed, surfaces smoothened and surfaces spray painted, if desired.
Formlabs Form 3
Fast and accurate printing with the Formlabs Form 3, SLA 3D printer. Used for making small parts and prototypes at a fraction of the cost to other 3D printing machines. Using a light processing unit with a powerful laser, parabolic mirror and spatial filter to give users a smooth and accurate print every time.
Formlabs Form 3L
The Formlabs Form 3L is designed for printing large parts and models, up to 5x larger than the Form 3, in house. By scaling up basic Stereolithography principles, the Formlabs resin 3D printer gives fast and affordable results, for the professional user.

workings of SLA printing and the potential benefits to your business.
The SLA process is flexible, clean and fast, helping to reduce both costs and your carbon footprint by keeping waste to a minimum. All of the required material transfers to the part, with any excess re-used in subsequent layers.
The only additional parts to consider are supports, common to most 3D printing technologies, to be broken away when the job is complete. These are calculated and built into the design automatically by the management software.
With a wide range of resins to choose from, and the ability to mix your own colours, SLA offers huge flexibility and range of design options. With fewer moving parts inside the build chamber, SLA printers can maximise the amount of space they give over to part production, reducing the overall size of the printer and making it easier to accommodate.
This ability to produce larger parts also helps SLA-produced tools to maintain structural integrity as it doesn’t require multiple smaller parts to be fused. For this reason, among others, the SLA printing process is renowned for producing hard-wearing, long-lasting, production-ready parts.
