How CAD and 3D Printing Work Together

• CAD Software: Used to design the 3D geometry of a part or product
• Export as STL: The CAD model is exported as an STL (stereolithography) file format
• Slicing: The STL file is sliced using software like Cura or PrusaSlicer into layers for the printer
• 3D Printing: The printer builds the object layer by layer using PLA, ABS, resin, or metal

Best CAD Software for 3D Printing

• Fusion 360: All-in-one CAD/CAM/CAE platform with STL export and generative design
• SolidWorks: Powerful parametric modeling with 3D print validation tools
• TinkerCAD: Beginner-friendly browser-based tool for simple 3D models
• AutoCAD: Useful for 2D base sketches and exporting to 3D workflows
• Blender: Great for artistic modeling and detailed organic shapes

Applications of 3D Printing + CAD

• Prototyping: Rapid model testing before mass production
• Product Design: Custom enclosures, tools, and consumer goods
• Medical: Custom implants, dental guides, and prosthetics
• Architecture: Scaled building models for client presentations
• Education: Teaching engineering concepts through hands-on modeling

Tips for CAD Modeling for 3D Printing

• Ensure the model is watertight (no gaps or open edges)
• Avoid overhangs >45° unless supported
• Check wall thickness and tolerance for print material
• Use STL repair tools like Netfabb or Meshmixer if needed
• Design with the printer’s build volume and resolution in mind
