As a leader in the additive manufacturing space, RE3DTECH is always looking to add new industrial 3D printing equipment to our growing list of technologies.
We’re in the process of reviewing SLA and DLP 3D printers, and while we haven’t pulled the trigger on a specific printer just yet, we’re already excited about the possibilities on the horizon.
Today, we’re providing an overview of these technologies so our customers can know what to expect in terms of properties, applications, and—perhaps most importantly—materials. Because each time we add a new 3D printing technology, we open the door for a whole new set of materials to work with.
What Is SLA and DLP 3D Printing Technology?
Stereolithography (SLA) and Digital Light Processing (DLP) are the two primary technologies used for resin 3D printing. While there are some differences between these processes—DLP is generally faster and the printers require less maintenance—their essential functionality is very similar.
Liquid resin is exposed to a light source in the form of a projector in the case of DLP or a laser in the case of SLA, and that light source cures the resin as it builds up layer by layer to create a desired shape.
Both SLA and DLP technologies are known for producing finely detailed parts with an extreme degree of accuracy, precision, and quality—plus an exceptionally smooth surface finish.
Many industries and applications leverage SLA and DLP technologies, however they are most ideal for functional prototyping, tooling and fixturing, and dental and jewelry applications that require minute details.
But perhaps the biggest advantage of SLA and DLP technologies is the wide selection of versatile materials compared to other 3D printing technologies.
Here’s a look at the open source DLP materials we’re most excited about. These materials are typically compatible with SLA technology as well.
