About this gig

Many buyers face problems with silicone molds and slip casting molds that crack, leak, stick, or dont print correctly. Poor 3D modeling results in unusable STL files, bad parting lines, and failed productionwasting time, materials, and money.


I specialize in 3D silicone mold and slip casting mold design created for real-world manufacturing. I deliver print-ready STL files optimized for 3D printing, silicone casting, resin molds, chocolate molds, plastic molds, and injection molding.


Every 3D mold design is engineered with proper draft angles, clean cavities, alignment, and smooth surfaces to ensure easy demolding and repeatable results. From simple mold blocks to complex multi-part molds, I create designs that work from prototype to production.
