3D Printing from Zero to Hero in Blender – FDM & MSLA (Udemy.com)

You want to design your own parts in Blender and print them, on a filament printer, a resin printer, or through a print service. This course is the practical path from a blank file to a print that holds together.

By the end you will model solid, printable objects, check them with Blender’s 3D-Print Toolbox, export STL, slice to G-code or resin files, and run jobs on FDM (Prusa-style) and MSLA (Elegoo Mars-style) machines. You do not have to rely on other people’s STLs.

Each project teaches a print problem: wall thickness, normals, overhangs, infill, supports, brim. Failed prints become something you can fix.

What we build

• Door grip (more than one method)

• Vase (more than one method)

• Phone stand

• Piggy bank

• Coin

• Phone case

• Photogrammetry / 3D reconstruction of a 12th-century font

• Cleanup and retopology of an imported model

What we use Blender, 3D-Print Toolbox, MeasureIt, Bolt Factory, STL export, FDM slicing and G-code, Chitubox for resin, Prusa-style FDM, Elegoo Mars-style MSLA, Meshroom for photo scanning, sending a model to a print service. FreeCAD where a CAD solid is the cleaner start.

Who this is for Beginners who want to 3D model and 3D print their own objects. Prior Blender helps but is not required. A three-button mouse is recommended.

Who this is not for If you only want a slicer tutorial and never want to model, pick something else.

Open Blender, pick a project, and print something that is yours.

What you’ll learn

• Model solid, manifold objects in Blender for 3D printing

• Check and fix prints with the 3D-Print Toolbox (thickness, normals, non-manifold)

• Export STL and slice to G-code (FDM) or resin files (MSLA / CTB)

• Print on a filament printer and on a resin printer

• Use infill, supports, brim, and bridging so jobs succeed

• Photo-scan a real object and prepare it for print

• Import an external model, retopologise, and make it printable

• Know when a print service is the better option

Requirements

• A computer that can run Blender (free)

• Three-button mouse recommended

• A 3D printer is useful but not required; slicing and print-service export are covered

Who it’s for

• Beginners who want to design and 3D print their own models in Blender

• Makers who already print downloaded STLs and want to model their own

• Anyone moving between FDM filament and MSLA resin workflows
