SiCast 405 – Advanced Ceramic Investment Casting Resin

Category: Investment Casting Resin
Wavelength Range: 385–405 nm
Technology: Open-Platform SLA / DLP
Primary Use: Printed ceramic molds, shells, and cores for complex investment casting applications

Description

SiCast 405 is Tethon 3D’s advanced ceramic investment casting resin for open-platform SLA and DLP printing systems. Developed as the next-generation successor to Castalite, SiCast 405 enables foundries, OEMs, and advanced manufacturing teams to print complex ceramic mold and core structures directly from digital designs.

Unlike traditional wax-pattern and dip-shell workflows, SiCast 405 can produce integrated ceramic shells, cores, internal channels, lattice features, undercuts, and fine cooling geometries in a single printed build. This makes it especially useful for development castings, complex hot-section components, and applications where conventional tooling adds cost, time, or design limitations.

After firing, SiCast 405 printed components convert into strong, dimensionally stable ceramic structures engineered to withstand demanding casting environments, including high-temperature nickel- and cobalt-based superalloy casting.

SiCast 405 is currently being used in advanced casting routes involving single-crystal nickel superalloys, including materials such as CMSX-4 and SC 180, where core geometry, thermal stability, surface finish, and clean removal are critical to successful castings.

Key Advantages

Designed for Single-Crystal and Directionally Solidified Casting

SiCast 405 supports demanding casting environments used for single-crystal, directionally solidified, and advanced equiaxed castings. It is applicable to turbine blades, vanes, airfoils, and other hot-section components requiring complex internal geometry.

Compatible with Advanced Superalloy Casting Routes

SiCast 405 printed ceramic cores and molds can be used in development and production casting workflows involving high-performance nickel- and cobalt-based alloys, including:

• CMSX-4
• SC 180
• René-type nickel superalloys
• Mar-M-type nickel superalloys
• Inconel-type alloys
• Cobalt-based superalloys
• Other directionally solidified and single-crystal casting materials, subject to foundry validation

Complex Internal Geometry

Print ceramic cores and molds with internal features that are difficult, slow, or impossible to produce using conventional tooling. SiCast 405 is well suited for:

• Cooling channels
• Thin internal passages
• Complex undercuts
• Integrated shell/core structures
• Lattice features
• Fine surface details
• Development geometries for next-generation turbine components

Reduced Tooling Dependence

By printing ceramic casting structures directly, SiCast 405 can reduce reliance on wax patterns, hard tooling, and multi-step shell-building processes. This is especially valuable for prototyping, short-run production, rapid iteration, and new hot-section component development.

Open-Platform Processing

SiCast 405 is designed for open-platform SLA and DLP printers operating in the 385–405 nm wavelength range, allowing customers to use existing additive manufacturing systems where process parameters can be controlled.

Foundry-Focused Performance

After firing, SiCast 405 produces ceramic structures intended for demanding foundry environments, with a focus on:

• Dimensional stability
• Thermal-shock resistance
• Fine feature reproduction
• Clean burnout
• Low residual ash
• Stable performance during molten metal casting
• Compatibility with complex investment casting workflows

Why SiCast 405?

SiCast 405 brings the design freedom of additive manufacturing to investment casting. By enabling printed ceramic cores, molds, and integrated shell structures, it gives foundries and engineering teams a faster path to complex castings without waiting on traditional tooling.

For turbine and aerospace applications, SiCast 405 is especially valuable where single-crystal casting, directionally solidified superalloys, internal cooling channels, and hot-section development create bottlenecks in cost, lead time, and manufacturability.

SiCast 405 helps customers print the ceramic structures needed to cast more complex metal parts, faster.
