3D Printing Software

Slicers

Slicers are programs that take 3D models and "slice" them into horizontal layers for the 3D printer to print. This is also where you will be adjusting layer height (affects detail/time of print), supports (needed to print overhangs), print speed/temperature (slight adjustments needed depending on the filament being used), and other settings. Most printers have a default slicer but some are better supported and most can be used with any printer.

Cura

The default slicer for the UltiMaker devices, but the arguable favorite in the 3D printing community. Actively being developed with updates coming out several times a year, often with industry changing advancements. Can be a bit more complex in advance settings, but nothing that isn't learnable through watching a few YouTube videos. Also has an option for community add-ons which offer several quality of life improvements.

FlashPrint

The default slicer for the Flashforge devices. Works well with these devices and can be used with other brands of printers, but nothing flashy or special that puts it above other slicers.

Modeling Software

To edit or clean up 3D models, there are several different programs one can use. Each has different levels of complexity and limitations.

Tinkercad

A web based design program that allows the user to create 3D models using predefined shapes. Shape dimensions can be modified free hand or inputting precise measurements. Users combine normal and "ghost" shapes to delete portions of objects. While it will load already created STL files, it does have a set limit on file size/triangle account. This is a great introduction into 3D modeling and a good resource to introduce to a patient to create their own project.

Blender

A free program revolving around 3D modeling and animation. A bit more in depth then other software, requiring time spend watching tutorials or simply messing around to get a feel for the process. Users can modify models on the mesh level by adjust vectors and face or use the sculpting mode for a more artistic approach. Will load most complex STL files and is a great way to combine two models into one (e.g. a lithophane and a stand).

Fusion360

Fusion 360 is a cloud-based 3D CAD program that utilizes the cloud storage for easier use in collaboration on complex projects. Another advantage of the cloud platform is that Fusion stores the entire history of the model including the changes to it. Numerous design options are available, including freeform, solid, and mesh modeling. The software is free for personal and noncommercial use, but has limitations on the number of projects stored on the cloud.

Meshmixer

While it is no longer being developed, Meshmixer provides straight forward and unique tools in editing mesh models including planner cuts, filling/hollowing models, and creating tubes. While likely not the first choice in creating models from scratch, these tools can be helpful in end stage processing.
