Mesh & Mix

Design your own creations by combining two or more models with a few simple steps. It’s as easy as “cut-and-paste”.


Create beautiful overlay textures using a variety of simple grid and pattern options.


Mold and refine surfaces real-time like virtual clay.

“To think that a 3D modelling software as advanced and complete as Meshmixer is available for free is a wonder of modern times and it keeps getting better.”

– Davide Sher, 3D Printing Industry

3D printing with Meshmixer

Printing your 3D model has never been easier with the latest release of Meshmixer.

Seamless digital-to-physical experience

Starting from any 123D software, 3D model in the Gallery, or any major 3D model file format, you can preview, refine and prepare your models to print with confidence.

.stl, .obj, .amf, .ply, .wrl

Supports any desktop 3D printer

Print directly from Meshmixer to your MakerBot†† or Type A Machines. Meshmixer is also compatible with Stratasys, and has the option to configure your own desktop printer.

†† Windows 8.1 only

Hassle-free 3D printing services

You don’t need to own a 3D printer to create amazing 3D-printed objects. Leave the 3D printing to our trusted partners: i.materialise, Sculpteo and Shapeways. Pick from dozens of different materials, colors and finishes, and preview your shopping cart right in Meshmixer.
