PLA vs PETG vs ABS: Which Filament Should You Use (and When)?

This is a longer, story-driven guide you can use as a template—not just a list of tips.

I once spent an entire afternoon “researching” and ended the day with… more tabs.

That’s when I realized my real problem wasn’t effort—it was decision friction.

I needed a repeatable way to turn fuzzy ideas into a clean next step.

The beginner mindset that prevents frustration

3D printing feels magical right up until the first failure. The best printers still fail—so the goal is not perfection, it’s a repeatable way to diagnose problems.

The first-layer rule

If the first layer is solid, the rest of the print has a fighting chance. If it’s bad, you’re basically printing a house on sand.

Setup checklist (the calm version)

  • Clean the bed (soap and water, or isopropyl on some surfaces).
  • Run bed leveling/mesh (if your printer supports it).
  • Print a first-layer test and adjust Z-offset slowly.
  • Start with PLA and a conservative speed profile.
  • Keep your filament dry; moisture causes random artifacts.

Troubleshooting flowchart (common failures)

  • Not sticking: clean bed → increase first layer temp → adjust Z-offset → try adhesive.
  • Warping: add brim → reduce cooling early → draft shield/enclosure if needed.
  • Stringing: lower temp → tune retraction → dry filament.
  • Weak parts: increase walls → more top layers → switch to PETG/ABS when needed.
  • Ugly top surface: increase top layers → reduce speed → tune flow.

FAQ

  • Do upgrades fix bad prints? Usually not. Basics first.
  • Why is filament storage important? Moisture creates inconsistent extrusion.
  • How do I improve fast? Print small calibration tests and take notes.

One-day challenge (do this today)

  • Pick one real task that’s been hanging over your head.
  • Set a 15-minute timer and run the template from this post.
  • Ship a “version 1” (even if it’s imperfect).
  • Write down one thing you’ll improve tomorrow.

Small reps beat big plans. Tomorrow, repeat with a slightly better prompt or checklist.
