Perfect Your Print: Solving 3D Perimeter Touch Issues

3D Printing can be a thrilling experience, but oh boy, the challenges! Ever faced that moment when your print layers or walls are misbehaving and not lining up right? Or those infuriating perimeter gaps? You’re not alone. With this guide, I’ll walk you, my tech enthusiast friends, through some nifty solutions. Dive right in!


So, what’s the deal with 3D Printed Perimeters Not Aligning? How can you rectify this hiccup? Here’s the rundown:
1. Tweak Printing Velocity
2. Understand the phenomenon called Under Extrusion and get the lowdown on tackling it.
3. Dial into your Extrusion Width Settings.
4. Always inspect your Model’s Design.
5. Investigate and Adjust Belt Tightness.
6. Stick to Pre-set Slicer Profiles.
7. Ensure the Wall Thickness aligns with your Nozzle Size.
8. Maybe give that Printing Temp a little nudge upwards.
9. Time for some Calibration – think Extruder Steps/mm.
10. Double-check that Filament Diameter in your Slicer software.

Understanding Under Extrusion in 3D Printing: Imagine if your printer’s filament flow can’t keep up with its speed, that’s under-extrusion for you. It’s like the printer having a little hiccup.

Got Under-Extrusion? Here’s How to Tackle It:
– Turn up that printing temp.
– Play around with the printing speed.
– Ensure harmony between layer height, temp, and speed.
– Inspect and if needed, swap out that PTFE tubing.
– Make sure your nozzle isn’t playing hide and seek – unblock it!
– Examine your extruder for any constraints. Remember, smooth is the name of the game.
– Adjust the angle for filament entry into the extruder.
– Remember to get your filament diameter just right. A snug fit, always!

Peeking into Extrusion Width Settings:
Noticed the same gaps in different areas of your print? Adjust the Extrusion Width. Sometimes, the software might overestimate the extrusion lines, creating those pesky gaps.

Model Design Got You Puzzled?
It’s like setting up for a photo – always preview it. You might just spot those gaps before the print starts. For rounded walls, give a slight thickness bump and you might be surprised!

Belt Tension, More Crucial Than You Think!
A printer’s movement, much like a ballerina’s dance, hinges on precision. Any slackness and your print might just trip up. Check the X & Y axis tension, ensure there’s resistance, and you’ll keep those misalignments at bay.

Starting Fresh with Slicer Settings:
Did you perhaps tinker too much with the slicer settings? Sometimes, going back to the basics does the trick. And while you’re at it, explore the thin wall settings.

Wall Thickness and Nozzle Diameter – The Dynamic Duo:
Ensure there’s harmony here. If there’s a minuscule gap that your nozzle can’t fill, you’re setting up for a perimeter party.

Feeling the Heat? Increase the Printing Temperature:
Sometimes, all your filament needs is a warmer environment to flow just right. Give that temperature knob a gentle push.

Calibration Time!
That E-step calibration can be a lifesaver. The goal? A perfect 100mm filament extrusion.

Got the Filament Diameter Right?
Manufacturers do a fabulous job, but nobody’s perfect. Whip out those calipers and measure thrice!
