OBJ File 3D Printing & Price Calculator
Drop your .OBJ model below β our viewer automatically triangulates quads and polygons, measures volume and overhangs, and gives you an instant 3D printing price.
4 Quantity and notes
How it works
1. Upload your model
STL, OBJ or 3MF. The file is analysed in your browser - size, volume and overhanging surfaces.
2. Choose material and settings
Material, layer height, walls, infill and supports. The price updates instantly.
3. Add to cart
The file is added instantly to your cart and uploaded when you confirm your order at checkout.
3D Printing Wavefront OBJ Models & 3D Scans
Seamless online quoting for Blender, ZBrush, Maya, and 3D scan meshes
π¨ Automatic Quad & N-Gon Triangulation
Unlike basic viewers that only accept triangles, our OBJ engine triangulates quad and polygon faces on the fly and supports negative relative vertex indices.
π Interactive Millimetre Rescaling
Models exported from Blender or ZBrush often arrive in metres or arbitrary scene units. Click any X/Y/Z dimension in the 3D viewport to scale your OBJ to the exact millimetre size.
β¨ Fine 0.12 mm Layers & Zero-Gap Supports
For organic sculptures, props, and detailed housings, select our 0.12 mm detail preset and dual-material Support Interface (Z=0 mm) for clean undersides.
Frequently asked questions
Does my OBJ file need to be manifold (watertight) for 3D printing?
Yes. A 3D-printable OBJ mesh must be a closed solid volume with wall thickness of at least 1.0β1.2 mm rather than zero-thickness single-sided planes.
Why did my Blender OBJ import at 1/1000th scale?
Blender defaults to metres (1 unit = 1 m), while 3D printers read 1 unit as 1 mm. Either set Scale to 1000 when exporting from Blender, or type your desired mm size directly in our 3D viewer.
Are .MTL colour textures printed from an OBJ file?
FDM parts are printed in your chosen engineering or aesthetic filament colour. You can also emboss or deboss an SVG vector logo onto any surface in the calculator.
Which material gives the best surface finish for OBJ models?
PLA and matte carbon-reinforced PLA-CF produce crisp details and hide layer lines remarkably well.
What is the maximum OBJ file size supported?
Up to 120 MB directly in the browser calculator.
