SLA – Laser Based Additive 3D Printing
Widely regarded as one of the more accurate additive technologies, SLA is commonly used amongst designers and engineers looking for fine detailed, small featured parts.
The process builds parts with a precise UV laser to cure and solidify thin layers of a photo-reactive resin. Once completed, support structures are removed and parts are hand finished creating a smooth surface finish with almost nonvisible 3D Print layer lines.
GoProto’s finishing service enables us to add paint and texture to SLA parts to create highly-cosmetic show models.

QuickCast™
High detailed, sacrificial patterns for prototyping and production of metal components with fast turnaround.
QuickCast™ or otherwise known as Investment Casting is an SLA build style designed to meet the needs of the Investment Casting industry. As an alternative to traditional wax patterns, the QuickCast build style consists of a hollow SLA pattern with an internal hexagonal support structure that reduces the amount of material to burn out. Ideal for large assemblies, this process provides invaluable shrink and gating information prior to hard tooling.
Investment casting is a manufacturing procedure that has been around for thousands of years. While there has been some developments in the process, the need for the pattern around which to make the cast shape remains a constant. Traditional tooling to create the patterns can take weeks or months, costing tens to hundreds of thousands of dollars.
3D printed casting patterns offer a tool-free, fast, reliable and accurate alternative to the traditional methods, reducing the costs of creating pattern by as much as 90%, and produced in one-tenth of the time.
Applications
- Aerospace
- Medical
- Defence
- Electronics
