What is an STL file?
STL (Stereolithography) is the most widely used file format for 3D printing in the world. It contains the complete three-dimensional representation of a piece of jewelry, described by thousands of triangles that form its surface with micrometric precision.
A jewelry STL file is created by a designer using software such as Rhinoceros, ZBrush, Matrix, or Blender. Once ready, this file is sent to a resin 3D printer, which reproduces the piece with extremely high precision—something impossible to achieve with conventional hand-carved wax.
How the complete process works
The production flow with STL files for jewelry follows these steps: 1) Digital design — the jeweler creates the jewelry in 3D software with all dimensions and details. 2) STL export — the model is exported in the industry-standard format. 3) 3D printing in castable resin — the printer reproduces the piece layer by layer with a resolution of 25 to 50 microns. 4) Direct casting — the castable resin piece is cast directly into gold, silver, or platinum, with no need for intermediate wax. 5) Finishing — polishing, stone setting, and final touches.
Why use STL instead of traditional wax?
With STL files, you have perfect reproducibility — print the same piece hundreds of times with identical precision. Speed — from order to mold in a few hours. Variety — access to libraries with thousands of ready-to-use designs. Cost reduction — less waste and production time. Scalability — on-demand or serial production with no additional setup costs.
MS Soluções para Joalheria
MS Soluções para Joalheria is a reference in technical jewelry design for 3D printing, with over 2,200 projects available: rings, pendants, earrings, solitaires, stackable rings, wedding bands, sets, and much more. All files are developed with a focus on real production viability — appropriate thicknesses for casting, correctly sized settings, and geometries that guarantee results at the workbench.
