The post explains how to create metalâcast objects from 3D prints by first printing a wax model with a resin printer (e.g., the $200âŻMarsâŻElegoo), then surrounding it in plaster, firing it to burn out the wax, and finally filling the cavity with molten metal such as pewter, silver or gold. It compares this methodâs cost to an Enderâ3 v2 3D printer and notes that resin printers need ventilation and a mask for fumes. The author warns about the hazards of melting metalâsteam pops can scatter materialâand suggests using reliable pewter sources free of lead; gloves, ventilation, and face shields are essential. As a safer alternative, he proposes printing jewelry directly in shiny PLA or metallicâlooking PLA and optionally applying vapor smoothing for extra gloss. Finally, he recommends selling metal pieces through a local jeweler who can cast them, while noting that plastic jewelry is lightweight, inexpensive, and unique compared to gold.
