The 3D20 is a complex machine with multiple subsystems. Knowing the different components of your machine can be very effective to understand your printer and explain any issues that you may be having to a customer service representative. The diagrams below should help you get to know your printer, and should be referenced when performing maintenance on your machine.

3D20 Hardware Walk Through
This video will provide you with a walk you through of features and named aspects of your Dremel 3D20 Idea Builder. This is very helpful for you to understand the user manual and effectively communicate with customer support.
Unclogging the 3D20
This video will walk you through the steps to properly clear out a clogged 3D20 extruder.
3D20 Nozzle Replacement
Read the Dremel 3D20 manual and these instructions before repairing a jammed extruder in your Dremel 3D20. Failure to comply with the warnings and instructions may result in fire, equipment damage, property damage, or personal injury. Always unplug Dremel 3D20 from its power before performing any service procedures. Failure to do so may result in personal injury and equipment damage. Use only Dremel approved materials and components. Use of object materials, or 3D objects other than Dremel approved object materials and genuine Dremel components may void warranty. Repairs on Dremel 3D20-01 may require the use of special tools (pulling devices and bearing press). Authorized repair centers have trained repair technicians and equipment necessary to perform these repairs.
