What is the best infill pattern for thin walls?

Dive into the mind-boggling realm of 3D printers! These intricate devices, loaded with multiple functions and parts, sometimes baffle even the best of us. Among the quirkiest of problems? A 3D printer churning out paper-thin prints. But worry not! This guide is your ticket to troubleshooting that pesky issue.


To counter a 3D printer that’s laying down too thin walls, consider turning up the heat on your nozzle. This gives the filament a more fluid-like quality, ensuring smooth dispensation through the nozzle. Altering the flow rate in your slicer settings can also be a game-changer, especially after switching materials.

This mysterious occurrence is often dubbed as under-extrusion. The reasons? Well, there’s a buffet of them! An incorrect filament diameter might just be the culprit behind those lackluster prints. But no worries, this guide will dissect the essence of under-extrusion, pinpoint its root, and empower you with knowledge to combat this tech gremlin.

Now, a deeper dive. At its core, under-extrusion is a fancy term for when your printer skimps on the filament, laying down less than what’s demanded. The tragic result? Prints riddled with gaps, appearing as though they’re on a plastic diet.

Now, you don’t always spot these voids right off the bat. Sometimes, the deceit is subtle. Your print may look solid but could crumble under the slightest pressure. That’s under-extrusion showing its sneaky side, producing fragile, brittle models.

Is Your Printer Skimping On Filament?
To be sure, there’s a nifty test. Print a basic 20mm cube bordered thrice. Perfect layering on top with no gaps between borders? You’re clear! But, if gaps are playing peek-a-boo, you’ve got under-extrusion on your hands. Oh, and if your printer’s left side gives a little click? It’s another hint at this devilish problem, indicating filament resistance in the extruder.

Determined it’s under-extrusion? Let’s unravel its causes:
Zooming Too Fast
3D printing isn’t a race! Printing at light-speed can compromise quality. Ensure the filament’s flow and printing speed are in harmony to sidestep under-extrusion.

Getting the Temperature Just Right
Temperature isn’t just about your morning coffee. In 3D printing, it’s pivotal! Too cold or too hot, and you’ve got a mess.

Filament Tales: Feeder & Spool Drama
The feeding mechanism is pivotal. Too lax or too tense, and the filament’s flow is disrupted.

Diameter Dilemmas
Ensure your filament diameter and printer settings jive! Or else, it’s the under-extrusion blues for you.

Nozzle Obstacles
A clogged nozzle is like a traffic jam, halting the smooth flow of filament.
