Complete Guide on How to Attain the Best Quality in FDM 3D Printing

by Nice Rapid | Feb 24,2021 | FDM 3D Printing

Contrary to popular opinion, achieving that outstanding quality in FDM 3D printing is not a walk in the park. Various factors come into play, not only depend on the 3D model that you are trying to produce but also dependent on the environmental factors as well as the setting in which the production is carried out.

For this post, we are going to look at the various factors that will help you achieve outstanding quality in FDM 3D printing.

Proper care and maintenance of the filaments

This may seem obvious, but a lot of people fail to take good care of their filaments, this mere fact can have a significant impact on your 3D printing process. It's always important to pay special attention and ensure that the filament is properly wound or attached to the spool.

The breaks and knots located on the thread block proper flow from the filament onto the clog or extruder resulting in more damage. Whenever there is the storage of larger quantities of filaments, keep in mind that you must have large storage space.

Another vital fact is, they should be in a place that's humidity-free, or else all of your materials will lose some of their key properties or your materials can go stale. Most professionals in the FDM 3D printing sector recommend the addition of filament filters to clean all the oil components and materials.

The sponge on the filters not only lubricates the entire filament but also clears all the dust using the standard mineral oil as well as canola. By doing this it will ensure that the nozzle and extruder are in peak and top condition.

Using the correct temperature

The quality of the FDM 3D printing is usually dependent on the temperature set for the specific purpose of extruding or the heated platform. Every raw material has its specific extruding temperature. Let's take for example PLA melts at about 200 degrees Celsius while ABS melts at around 240 degrees Celsius.

The sudden increase will certainly influence the end-product while the low temperature will make the filament quite difficult to extrude. It's always vital that you set the right temperature on the heated platform.

3D prints with supporting structures

One of the most important points that you should keep in mind is that the 3D prints must use support structures as well as rafts especially when you are printing highly detailed and complex objects.

The key to your project's success is getting the right thickness on your rafts from the distance between the support and object plus the density. A denser support system is usually great but may be quite difficult to remove after 3D printing.

The quality of the support system is also dependent on the type of software that's being used. Different software and apps can create better or less adjoining structures which in the end can have a huge impact on the quality of the 3D prints.
