Frequently Asked Questions (FAQs)

Q: What is the difference between CAD software and a Slicer?
A: CAD (Computer-Aided Design) software is used to create and design the 3D model itself (e.g., Fusion 360, SolidWorks, Blender). A Slicer takes that finished 3D model and translates it into G-code, the step-by-step instructions that tell your 3D printer exactly how to build it (e.g., Cura, PrusaSlicer, Lychee).

Q: Is free 3D printing software actually good?
A: Yes, absolutely. Some of the most powerful and widely used software in the world, like UltiMaker Cura, PrusaSlicer, and Blender, are completely free and open-source. They often rival or exceed the capabilities of paid software.

Q: Can I use one slicer for both my FDM and Resin printers?
A: Generally, no. FDM and resin (SLA) printing are fundamentally different processes. While some professional software like VoxelDance supports both, most tools are specialized. You will typically need a dedicated slicer like Cura for FDM and Lychee or ChiTuBox for resin.

Q: I keep getting print failures. Can better software help?
A: Definitely. Software plays a huge role in print success. Using a slicer with better support generation (e.g., Lychee for resin), more accurate previews (Simplify3D), or better-tuned default profiles (PrusaSlicer) can dramatically reduce failures.

Q: What does “parametric modeling” mean?
A: Parametric modeling (used in Fusion 360 and SolidWorks) means your design is built on a history of defined features and dimensions (parameters). If you need to change a dimension, the entire model updates intelligently based on those rules. This is ideal for engineering. Non-parametric software (like Blender) is more like digital clay—great for art, but harder to make precise changes to a single dimension later.
