Autodesk MeshMixer vs. PTC Creo

Autodesk MeshMixer is best for repairing STL files and basic modifications toward 3D printing. It is excellent for hollowing out models and adding escape holes for SLA printing or lost-wax casting. Its CSG (Boolean) functions to combine different meshes are good too and seldom cause the program to crash. There is even an integrated algorithm to optimize the layout of multiple files on a print bed in case of small-batch production. Autodesk MeshMixer's sculpting tools are there yet limited and there are a few better alternatives. Best of all, it is completely free.

I wouldn't suggest it to my worst enemy. My colleagues worked with other CADs and, in my experience, complain every day about this CAD, about how much things it doesn't have or do, etc. One of them keeps telling me, in their opinion, how even CREO Direct is far superior, easy to use, faster and better. In my opinion, it's a CAD that requires constant attention at what you do, how you do, when you do because it doesn't do it for you.

• Auto-repair function works fast, and if it does not completely cover all problem areas, manual fixes will work 99.5% of the time.
• Remeshing algorithm is fairly slow but does a wonderful job in creating meshes with homogeneous or adaptive triangulation.
• It contains a comprehensive set of tools to optimize and prepare STL files for 3D printing, such as hollowing and support generation.

• PTC Creo contains many advanced tools with better optimization for creating part models and other production related drawings.
• The initial concept designs can be done more adequately.
• The parameters of 2D drawings can be changed easily by editing the 3D model.
• The productivity can be increased by customized tools for modeling.

• The remeshing tool needs to be faster, as in some cases it takes up to a day of waiting time.
• The sculpting tools need the addition of a proper brush for creating sharp creases and ridges.
• The standard shape library is rather limited. It would be nice to have this connected to online repositories such as Thingiverse, MyMiniFactory, or Cults3D.

• Providing guidance through using tools is lacking in Creo. There is a small area where the text is displayed at the bottom that is supposed to help guide you, but many times the guidance doesn't make sense.
• Layers are a hassle in Creo. Unless you know how to set up your config file to do it automatically, you have to add each item to the appropriate layer.
• There is a lack of automation in Creo. In some other CAD packages, you can add holes or the like on a pattern of features. Not so in Creo.

I liked the training manuals I used to learn some, as I didn’t have CAD background in college or before this job. My coworkers were able to share with me what they learned in PTC training and I was able to get support online and through reading.

Using Blender for STL file preparation is like swatting a mosquito with a wrecking ball, plus its boolean functionalities can be glitchy. ZBrushCoreMini proved too limiting as a sculpting tool, but so did Autodesk MeshMixer, so I am sticking to Sculptris. Materialise Magics and Netfabb are somewhat better at STL file repair and offer more advanced functionalities. But Magics does not remesh as well and Autodesk MeshMixer is far more compact and faster than Netfabb, so remains my weapon of choice.

PTC Creo is much better than other software at allowing collaboration across multiple users, even multiple plants/locations. We went from an older non-parametric industry standard software to PTC Creo because we could save massive amounts of time by using the parametric assembly features of PTC Creo along with the the Windchill drawing organization functions.

• It speeds up projects by streamlining the CAD-to-3D-printing workflow
• As an advanced user, I have written a few tutorials about it as well

• Having PTC Creo as our primary tool positions us as forward thinking and creative in the eyes of our clients.
• PTC Creo constantly evolves in the ability to increase our productivity; new capabilities and features are added, which reduce our level of effort for some tasks.
