eSUN Invites You to the China International Foundry Expo 2026

From May 6 to 9, the China International Foundry Expo will be held at the National Exhibition and Convention Center (Shanghai). As a globally recognized 3D printing material brand, eSUN will showcase a range of industrial-grade 3D printing materials, focusing on practical application solutions of 3D printing technology in modern casting processes and workshop production.

In traditional casting industries, whether investment casting or sand casting, mold development for complex castings often faces challenges such as long development cycles and high mold costs. For single-piece customization or small-batch production, the high cost allocation of molds is particularly significant. In recent years, 3D printing, with its “tooling-free” advantage, has gradually moved from concept validation to actual manufacturing.

Based on real application needs, eSUN will focus on showcasing the following two core material solutions at this exhibition:

PLA-Cast: Low Ash, High Precision, Designed for Investment Casting Applications

Low Ash Content

The ash content of PLA-Cast is as low as 0.003% after burning in high-temperature casting environments, approaching a “zero-ash” level. This low ash characteristic means minimal residue during casting, which significantly reduces defects such as inclusions and porosity when molten metal is poured into the mold, ensuring superior surface finish and internal quality of the final metal castings.

High-Precision Forming

Verified in practice, PLA-Cast printed models exhibit stable dimensions and clear details, meeting the precision requirements of investment castings.

Carbon Fiber 3D Printing Materials: A Lightweight Choice for High-Strength Tooling and Fixtures

In daily production and pre-validation processes in foundries, high-strength auxiliary tooling is indispensable. This time, eSUN will also highlight carbon fiber-reinforced 3D printing materials, including PET-CF, PA-CF, PA12+CF, ABS-CF, PETG-CF, PLA-CF, etc.

Excellent Mechanical Properties:By incorporating high-rigidity carbon fibers into the base material, the strength, hardness, and wear resistance are significantly improved, enabling partial replacement of metals for manufacturing high-strength inspection tools, assembly positioning fixtures, and robotic grippers in automated production lines.

High Dimensional Stability:Carbon fiber materials feature extremely low shrinkage, making them less prone to warping or deformation during large-scale structural printing, effectively ensuring the strict dimensional accuracy required for industrial assembly and prototyping.

eSUN provides a wide range of 3D printing material solutions. Whether you are looking for cost-effective alternatives to traditional mold-making or are interested in applying 3D printing in workshop production, we sincerely welcome you to visit the eSUN booth (4.1H 4A89) to explore new materials, technologies, and applications, or discuss customized material solutions.
