PLA Cast White Filament for Metal Casting 1.75mm 1Kg eSun

The PLA-Cast from eSun is a PLA filament specifically developed for the lost wax casting process (Lost-PLA-Casting). The printed model is embedded in a ceramic casting material, burned out in the kiln, and leaves virtually no residues – the ash content is only 0.003%. This replaces the labor-intensive wax burnout process and significantly reduces production costs and lead times. The high printing precision enables the detailed transfer of the finest geometries into metal. The filament is suitable for casting processes where bronze, brass, silver, gold, or other alloys are cast. The model should be smoothed after printing before embedding as surface structures are directly transferred to the casting result.

Properties:

• Ash content of only 0.003% after burnout leaves virtually residue-free casting cavities for clean metal results
• Replaces the wax burnout process and enables complex cast parts directly from the 3D printer without silicone molds or wax injection systems
• High printing precision for the detailed transfer of delicate structures, engravings, and fine geometries into the casting result
• High tensile strength of 76.85 MPa (XY) for dimensionally stable models that withstand embedding in the casting material without deformation
• Broad compatibility with standard FDM printers and standard foundry processes without special equipment
• Suitable for silver, gold, bronze, and brass casting as well as other non-ferrous metal alloys in the fine casting process

Application examples:

• Jewelry casting in silver, gold, or bronze – transfer rings, pendants, and bracelets directly from 3D printing into metal
• Prototypes for mechanical parts in metal casting without tooling costs for permanent molds or wax injection systems
• Art casting and sculptures with complex organic shapes that are difficult to produce with traditional casting methods
• Small series production of metal parts for industrial applications with a short time window from design to casting
• Dental prosthetics and medical metal parts in small series via the lost-PLA process
