Formlabs Clear Cast Resin for Form 4, 1L

Formlabs Clear Cast Resin for Form 4, 1L

The Formlabs Clear Cast Resin, specifically designed for the Form 4 3D printer, is a highly precise material used for creating molds for metal part casting. This resin allows for direct printing of patterns that can be burned out and cast, featuring very low thermal expansion, minimal ash residue, and no heavy metal traces.

The 1-liter photopolymer Clear Cast Resin is ideal for 3D printing accurate, low-ash, and low-heat models for investment casting directly in your workshop.

Clear Cast Resin is recommended for use with larger parts in combination with grid software, suitable for geometries over 3 mm in thickness.

Key Benefits

• In-house mold production is made possible. With Clear Cast Resin, you can directly print casting patterns using the Formlabs Form 4 SLA 3D printer, reducing costs, shortening production times, and enhancing iteration and flexibility.
• Clean burnout process. Clear Cast Resin burns cleanly with low ash and no metal traces, preventing contamination of the final part.
• Minimal thermal expansion. Its top-notch thermal expansion ensures reliable casting shells with minimal cracking.
• Precision and versatility. Create highly accurate models with a tolerance of up to 0.25 mm. This resin works with any metal or shell system, enabling foundries to cast new designs quickly.
• Proven expertise. Formlabs produces industry-leading resins at its advanced facility in Ohio, utilizing this experience to develop Clear Cast Resin for their own SLA printers.

Clear Cast Resin Applications

Investment casting using Clear Cast Resin is widely employed in industries requiring precise, custom metal parts, such as engine components, turbines, medical implants, surgical tools, dental prosthetics, jewelry, souvenirs, industrial components, and more.

3D Printing Patterns for Investment Casting

Investment casting, also known as lost-wax or precision casting, is a method of creating metal parts with complex shapes and high accuracy. This traditional process has been revolutionized by modern 3D printing technology.

The process involves printing an exact replica of the final part. Traditionally, wax models were used, but this was time-consuming. The 3D-printed part is then coated with a refractory material. Once hardened, the wax is melted, leaving a cavity that is filled with molten metal. After cooling, the final metal part is produced.

Workflow for 3D Printed Investment Casting Patterns

3D-printed patterns can replace wax molds, enabling complex shapes and quicker iterations without specialized tools. The process typically involves:

• Using software like Materialise Magics or Formware to create the shell, lattice, and add drain holes.
• Setting orientation, support, and slicing the pattern in PreForm.
• Printing the pattern.
• Washing, post-curing, and removing supports.
• Sealing drain holes with wax or a small amount of Clear Cast Resin.
• Attaching the pattern to a casting tree and proceeding with the casting process.
