PLA-Cast——Low Ash. High Precision. Ready for Investment Casting

PLA-Cast is a professional material developed by eSUN specifically for investment casting applications. It features high printing precision, and after the printed parts are coated with slurry and burned at high temperatures, almost no residue remains. With extremely low ash content and relatively high strength, the material is easy to post-process, providing reliable material support for the application of 3D printing in the investment casting industry.

1. Low Ash Content

The ash content of PLA-Cast is as low as 0.003% after burning under the high temperatures of casting, nearly reaching the “ash-free” level. This extremely low ash means minimal residue remains during casting, significantly reducing defects such as slag inclusions and pores when molten metal is poured into the mold, making it highly suitable for precision casting.

2. High Precision Forming

Traditionally, casting primarily used resin materials with high precision. Verified through practice, PLA-Cast provides stable dimensions and clear details in printed models, meeting the precision requirements of investment castings.

Application Analysis of 3D Printing in Investment Casting

Investment casting is a near-net-shape technology suitable for forming complex thin-walled parts, with high dimensional precision and minimal need for finishing. Traditional methods for producing investment molds are complex, costly, and time-consuming. The advent and application of 3D printing has greatly shortened the production cycle, eliminating the need for wax pattern molds and reducing mold modification steps. It offers low cost, short lead times, and high efficiency for small-batch production.

PLA-Cast Real Applications & Customer Feedback

Our company is mainly engaged in metal casting and has gradually introduced 3D printing into our core business in recent years. At present, 3D printing technology and related products have successfully passed production verification and received wide recognition from both domestic and international customers.

eSUN PLA-Cast material leaves extremely low ash after burning, and the surface quality of the castings can rival that of traditional pure wax molds.
