This is the largest resin 3D printer we’ve ever seen, and it completely changes how parts can be produced.
Resin printing has been around for a long time, but machines like this 400-litre SLA system take it to a different level, allowing not just large parts, but hundreds of smaller components to be produced in a single build.
In this walkthrough, we break down how stereolithography (SLA) actually works, using a laser to cure liquid resin layer by layer, and how that compares to other additive manufacturing methods like SLS and FDM.
The discussion covers where resin printing excels, particularly in surface finish, fine detail, and applications like prototyping, mould making, and casting patterns. We also look at material properties, including clear resins, high-temperature options, and how resin parts compare to thermoplastics in strength and durability.
We also explore production advantages, including how larger machines improve efficiency by printing multiple parts at once, as well as the full post-processing workflow from cleaning and UV curing through to final part readiness.
If you are considering additive manufacturing for functional or prototype parts, this gives a clear overview of where large-format resin printing fits and how it compares to other technologies.
