6 Things You Should Know About 3D Printing Large ABS Parts

In the video, Erick Wolf reviews the technical requirements for large format additive manufacturing of parts in acrylonitrile butadiene styrene (ABS) with fused deposition modeling equipment.  They are as follows:

1. Enclosed Build Environment.  

Containing heat is absolutely mandatory because ABS, more so than PLA for example, tends to contract at high rates when it cools. Also, an enclosed build environment also tends to contain a large portion of the ABS odor.

2. Powerful Heated Build Plate

A powerful heated build plate is also critical when printing large ABS parts.  So is the power supply, as getting the build plate to over 120C can be very power intensive.

3. Adding Heat To The Chamber

For heating large build volumes, a heated bed is a good start, but simply not enough when dealing with large prints.  Temperature-controlled chamber heaters can precisely control the chamber temperature.  

4. Surface Adhesion

Appropriate surface adhesion goes for nearly any part you will make.

5. Large Extrusion Nozzles

As print time is directly proportional to material flow through the nozzle, the more material can flow, the faster we can finish the print.

6. Backup your print

You should use a system with the ability to backup your print to save your work.
