Frequently Asked Questions

What is the best 3D printing filament for beginners?

PLA is the best starting filament — it prints easily at 190-220°C without an enclosure and produces good results. Once comfortable, PETG offers better strength and temperature resistance for functional parts.

How do I choose the right filament?

Consider the application: PLA for display models, PETG for functional parts, ABS/ASA for heat/sunlight exposure, TPU for flexible parts, and specialty filaments for engineering applications. Each has specific printer requirements.

What temperature should I print different filaments at?

PLA: 190-220°C nozzle / 50-60°C bed. PETG: 220-250°C / 70-80°C. ABS: 230-260°C / 100-110°C (enclosure needed). Nylon: 240-270°C / 70-90°C. Always check manufacturer recommendations for specific brands.


Beginner's Guide Tutorial for full-colour 3D Printing !

by

Full-colour 3D printing opens up a world of possibilities, from realistic prototypes to artistic multi-colored models. This guide covers the main technologies and methods available to achieve vibrant, multi-color prints.

The video below provides an overview; read on for in-depth explanations and up-to-date recommendations.

Comparison chart of full-colour 3D printing methods including multi-material, MMU, SLA color, painting and filament swap

Methods for Full-Colour 3D Printing

There are several approaches to adding colour to your 3D prints:

  • Multi-material printers – Use multiple filaments simultaneously (e.g., Bambu Lab AMS, Prusa MMU). Seamless colour blending and gradients.
  • MMU (Multi-Material Upgrade) – Retrofit kits for existing printers, like the Prusa MMU3 or Mosaic Palette.
  • SLA colour printers – Liquid resin printers with multiple resin tanks (e.g., some full-colour SLA machines).
  • Painting and post-processing – Hand-paint or use airbrushing for detailed colour work.
  • Filament swap – Manual filament changes during print for simple colour transitions.

2025 Update: The Current Landscape

In recent years, Bambu Lab has revolutionised multi-colour printing with their AMS (Automatic Material System) integrated into printers like the Bambu P1S. Prusa continues to refine their MMU3, which works with the Prusa i3 MK4 and the new Prusa CORE One. These systems allow up to 5 colours with smooth transitions.

For resin, full-colour options remain limited but emerging. Chitubox and other slicers offer support for multi-resin setups with manual tank changes.
