3D technology allows HVAC installers to solve problems with space and irregular shapes. A 3D scanner captures the exact measurements of a ceiling opening, and a custom duct adapter is designed. This eliminates sheet metal work and manual cutting errors, speeding up the installation.
Scanning and modeling: the digital workflow 🔧
The process begins with a scanner like the Revopoint POP 3 or the Einscan-SE to capture the geometry of the space. Then Fusion 360 or Blender is used to model the transition piece. The file is exported to STL and printed in PLA or ABS with a printer like the Creality Ender-3 or Bambu Lab X1. The result is a lightweight, durable piece that fits without needing putty.
The day I printed a split and got a paperweight 😅
Of course, it's not all glory. My first attempt to print a custom diffuser ended up looking like a deformed flan. The printer decided that PLA was happier melting in the air than forming a grille. But hey, now I have a desk ornament that justifies my filament addiction. Good thing the client didn't see it.
