Additive Manufacturing: Troubleshoot 3D Prints

Learn how to fix common 3D printing problems, such as prints that don't stick to the bed, pimples and dimples, and geometry issues.

Introduction

• When 3D prints go wrong
• Who this is for?

1. Issues Caused by Printer Hardware

• Overview: Issues caused by printer hardware
• Parts of a 3D printer
• 3D prints not sticking: Geometry and nozzle height
• 3D prints not sticking: Surface and materials compatibility
• 3D prints not sticking: Temperature effects
• Printer over- or under-extruding
• Pimples, dimples, and stringing
• Test parts, printing square, and backlash
• Part dimensions incorrect
• Printer geometry-related problems
• Filament jams and heat creep
• Clearing a nozzle clog without disassembly
• Nozzle replacement issues

2. Filament Effects on a Print

• Filament-specific issues
• Extruder temperature and cooling issues
• Choosing a material for a surface quality
• Tips for creating transparent prints with filament
• Handling abrasive filaments

3. Part Geometry Considerations

• Geometry considerations overview
• Thin-walled prints
• Vase prints
• Tall, skinny prints
• Printing solid
• Orienting parts for strength
• Prints with curves and holes
• Interlocking parts and horizontal size compensation

4. Identifying Software-Related Print Issues

• 3D printing software workflow
• Slicing and host programs
• Print configuration management
• Creating support
• Infill effects
• Ordering operations within a layer

5. Issues with Multiple Causes

• Systems-level debugging
• Debugging surface quality issues
• Creating detailed features
