Exporting Models

Exporting geometry correctly bridges the gap between digital workspace assembly and physical fabrication. Every manufacturing pipeline requires specific spatial tolerances, unit scales, and polygonal tessellations. Whether preparing a multi-body part for additive manufacturing or sending assets into real-time rendering environments, selecting the appropriate file format ensures your dimensional accuracy remains intact without missing facets or inverted normal artifacts.

Selecting the Right Format: STL, OBJ, GLB, and SVG

Standard manufacturing setups rely on the stereolithography (.STL) format, which converts surfaces into tessellated triangle meshes ideal for 3D slicing software. When color attributes and multi-part hierarchies matter, the Wavefront (.OBJ) or GL Transmission Format (.GLB/.GLTF) delivers material data alongside vertex coordinates. For laser cutters, CNC routers, and vinyl plotters, exporting 2D cross-sections as .SVG vectors isolates flat profile perimeters with exact millimeter calibration.

Ensuring Watertight Geometry and Wall Thickness

Successful physical fabrication requires a manifold, airtight outer boundary. Always verify that overlapping solids have been properly combined using boolean union tools rather than simply grouped visually. Internal voids and intersecting zero-thickness planes can confuse slicing algorithms, resulting in toolpath calculation errors. Run an inspection on thin overhangs and critical load-bearing walls prior to final output.
