Accura 25

Accura 25 is a durable and flexible SLA 3D printing material. It’s ideal for snap-fit part designs, as a master pattern for urethane casting, and conceptual modeling. Accura 25 can be used for functional prototyping or end-use parts and has excellent resolution, dimensional accuracy, and can be primed and painted after printing.

Note that any surface in contact with support will have small nubs in the final product as a result of support removal. To optimize the overall surface smoothness of the part, avoid extra overhangs, steep slopes, or large flat planes that may add more structural support.

Cost Saving Tip

Parts can be designed hollow to reduce material usage. Make sure to design a drainage hole that’s at least 4mm in diameter to allow removal of trapped resin. Surrounding walls should be at least 2mm thick to ensure a successful print.

About the Process

Stereolithography, or SLA, is a 3D printing technology known for achieving highly detailed and functionally accurate parts. The technology utilizes a mirror that is programmed to direct an ultraviolet laser to draw and cure a part’s cross-section onto a vat of photopolymer resin. After each layer, the build platform lowers and a recouter blade wipes over a new layer of material on the top of the tank.

Once the part is complete, it is removed from the build chamber, cleaned of support and excess resin (typically using isopropyl alcohol), and then placed in a UV oven for further curing. This ensures the part reaches its optimal physical properties.

Prototyping In-House vs Outsourcing: The ROI for Mechanical Engineering Teams

As product development cycles accelerate, engineering leaders face a recurring strategic question: How fast can we prototype—and where does it make financial sense to build? With premium compensation levels for mechanical engineers (especially with seniority and years of experience), the opportunity cost of hands-on prototyping has never been higher. When factoring in loaded labor rates, […]
