eSun PLA-Cast

Optimized for Investment Casting

PLA-Cast is specifically formulated to serve as a pattern material in investment casting workflows. Printed parts can be embedded in plaster or investment material and later burned out in a kiln, leaving a cavity that can be filled with molten metal. This process allows users to transform highly detailed 3D printed models into metal components with precision.

Clean Burnout Performance

One of the key advantages of PLA-Cast is its clean burnout behavior. During the casting process, the material decomposes with minimal ash residue, helping to maintain the quality of the mold and reduce the risk of defects in the final cast part. This makes it especially valuable for applications where fine details and surface quality are important.

Excellent Detail and Printability

PLA-Cast retains the user-friendly printing characteristics commonly associated with PLA. It extrudes smoothly, provides consistent layer adhesion, and supports the production of intricate shapes with fine detail. This makes it suitable for producing complex designs that would be difficult or time-consuming to create using traditional casting pattern methods.

Ideal for Jewelry, Art, and Metal Prototypes

Thanks to its casting-focused properties, PLA-Cast is widely used for jewelry making, artistic metal pieces, and functional metal prototypes. Designers can rapidly iterate on digital models, print casting patterns, and transform them into finished metal objects with precision and efficiency.

Typical applications include:

• Jewelry casting patterns

• Artistic metal objects and sculptures

• Custom metal components

• Prototyping for metal parts

• Small batch casting projects
