The Initial Guide to CAD Software for 3D Printing
4 min
To create precise, functional, or artistic 3D printed objects, you need the right CAD (computer-aided design) software. CAD software is the backbone of 3D printing. It allows users to design, modify, and optimize 3D models before sending them to the printer. Unlike general-purpose 3D modeling tools, CAD programs for 3D printing focus on precision, structural integrity, and compatibility with slicing software (which converts designs into printer-readable instructions). This article will take a look at the best CAD tools for 3D printing, their features, and how to choose the best one for your needs.
How to Choose the Right CAD Software
Device compatibility
CAD software is device-dependent, and users of different systems should be aware of the following limitations:
Browser/cross-platform users: Prioritize Tinkercad or Onshape, both of which are completely cloud-based and can be operated on any device without installation.
Mac users: You can choose Fusion 360, FreeCAD, Shaper3D or Plasticity, but please note that some software requires downloading the client.
Linux users: Only FreeCAD and Plasticity provide native support, but the functions of both are sufficient to meet most needs.
Windows users: Have the greatest degree of freedom, all mainstream software are compatible.
Mobile scenarios: If you need to model on an iPad, Shaper3D's touch-optimized design can significantly improve efficiency.
Cost considerations
1. Completely free tools
Tinkercad: Autodesk's entry-level software, no hidden fees, suitable for simple model design.
FreeCAD: Open source community driven, supports parametric modeling, but the interface and function updates are slow.
2. Free but limited tools
Fusion 360: The personal free version is limited to 10 active projects, suitable for non-commercial use;
Onshape: The free version has limited functions, and all files are public by default, with low privacy.
3. Paid tools
Plasticity: 30-day free trial, basic version one-time payment of $150, focusing on direct modeling, suitable for complex surface design.
Modeling logic
Parametric modeling (such as Fusion 360, FreeCAD): Generate a model by defining sketch dimensions and constraints. When modifying, you only need to adjust the parameters to automatically update the design. Suitable for engineering projects that need to repeatedly optimize dimensions.
Direct modeling (such as Plasticity, Shaper3D): Allow users to directly drag, push and pull the model surface, which is more suitable for artistic or organic shape design, but has weak control over dimensional accuracy.
Combined modeling (such as Tinkercad): Build models through Boolean operations (superposition, cutting basic geometric bodies), intuitive operation but limited flexibility, suitable for rapid prototyping.

CAD to 3D Print: How to Go from Design to Finished Part
When people first hear about going from CAD to 3D print, it sounds almost too simple: design a part, hit print, and you’re done. But anyone who’s actually tried it knows there are a few critical steps hiding in between. The way you export your CAD file, the software you use to prepare it, and how you handle the slicing process can make the difference between a clean, accurate print and something that belongs in the scrap pile. That’s exactly why many engineers and makers turn to JLC3DP and other 3D pr......
G-Code 3D Printing Commands: Tutorial, List & How to Use Them
(Freepik) If you’ve ever peeked insidfe a 3D printer’s sliced file and seen a wall of cryptic letters and numbers, congrats, you’ve met G-code. It’s not flashy. It’s not forgiving. But it’s the language that tells your printer exactly how to bring your model to life, line by line, millimeter by millimeter. Most users never touch G-code because slicers handle it automatically.
