Add ANY Logo to ANY 3D Print for FREE! (No CAD Needed)
How do you add a logo to an existing 3D print without CAD? In this step-by-step Bambu Studio tutorial, I show you how to turn a logo image into a FREE STL using MakerLab, then add it to almost any 3D model—including curved surfaces—using merge and Mesh Boolean tools.
Custom 3D printing doesn’t have to mean designing from scratch. Learn how to create raised logos, cut recessed logos into models, and make logo details follow the contours of a golf ball, Croc-style shoe, or football helmet. The same techniques work for business branding, school projects, sports teams, personalized gifts, and one-of-a-kind prints.

🎯 WHAT YOU’LL LEARN
• Convert a PNG/JPG logo or graphic into an STL without modeling it in CAD
• Use MakerLab’s “Image to Keychain” generator for far more than keychains
• Import, rotate, align, scale, and merge logo parts with another STL
• Add a raised, multi-colour logo to a LEGO-style brick
• Use Mesh Boolean Subtract to cut a logo-shaped opening in a pumpkin
• Use Mesh Boolean Intersect to preserve curved surface details
• Apply a logo to a golf ball, Croc-style shoe, and football helmet
• Adjust uniform scaling, model positioning, colours, and print orientation

💡 QUICK ANSWERS
Q: How can I convert a logo image to an STL for free?
A: Open MakerLab’s Image to Keychain tool, upload your image, choose the colours and settings, then export the generated STL.
Q: Can I add a logo to a 3D model without Fusion 360 or Blender?
A: Yes. Import the logo STL into your slicer. Merge it for a raised design, use Boolean Subtract for an inset/cutout, or Boolean Intersect to match the shape of a curved model.
Q: Does this work only in Bambu Studio?
A: No. The video demonstrates a Bambu-style slicer workflow; similar model merge and Boolean operations may be available in other slicers, although menu names and workflows vary.
Q: Why use Intersect instead of just sticking letters on top?
A: Intersection creates a logo surface that follows the underlying model’s texture or curve for a cleaner, more integrated finish.
