Getting better prints
This page is meant to give a few tips that may help you improve your prints or just be helpful in general. Before reading this page it might be a good idea to check out our Visual troubleshooting guide. That page goes through some of the most common problems you might encounter. There will be a fair bit of overlap between this page and the troubleshooting guide as some of these tips are shared on that page to deal with actual problems. Think of these guides as problem fixing versus fine tuning.
If you've been printing for a while you'll likely already know most of the things mentioned in this document. But if you're new to 3D printing the tips here could be of great help.
It should also be noted that this page is skewed towards the Ultimaker2 using PLA filament, and cura as the slicer. A lot of the information here applies in other situations as well however.
Here's a list of links to the different sections in this document. We would recommend that you read through it all though as 3D printing is a complex process where a combination of settings and "tricks" is often needed for the best result.
Printer - Adjustments made to the hardware, or settings on the printer
· Feed your printer with good quality filament
· Limit heated bed temperature to a minimum
Cura - Tweaks relating to the slicer
· Learn to love the "Layer view"
· Choose layer thickness to match your model
· While boring, printing slower is often the key
· Print more than one model at once to increase cooling
· Enable "Cool head lift" for more cooling time
· Change how early your fans come on
· Optimize orientation to make it easier to print
· Tricks to make a layer fill completely solid
· Print hollow to save plastic and time
· Z-scar
· Line support and bed leveling
Design - A few thoughts on how to best design for printability
· Design custom supports instead of relying on auto generated to lessen surface
· Create a span instead of a steep overhang if possible
· Use chamfers to produce cleaner bottom edges
· A trick to create better looking top surfaces
