CHALK Filament

Introduction

Composite 3D Printing filaments are a mixture of a carrier polymer (like PLA or ABS) and an additive that alters or enhances the 3D filaments aesthetic and physical properties.

Using a carrier polymer that can be easily printed, like PLA, means that some of the properties of the additives which could not normally be easily 3D printed can be enjoyed.

The ratio of carrier polymer to additive will vary between manufacturers. An important consideration when selecting a composite 3D printing filament is that the higher the percentage of additive, the more abrasive the filament will be. This can lead to damaging the nozzle of your 3D printer. For high ratio composites this can only be avoided using a hardened nozzle.

You should also consider how much post-processing you want to carry out on your composite 3D print. To get the desired finish, some composite filaments will require extensive processing with rock tumblers and polishing creams whereas other composite filaments will require little or no processing to achieve the desired finish.

Chalk composite 3D printing produces very aesthetically pleasing final products with the look and feel of very soft stone. Chalk composites are easier to print with than other composites but still slightly trickier than a normal polymer.
