M3D Pro Disassembly- Alpha 
 

In this guide we will explain how to disassemble the Pro so you can remove the gantry’s and 
extruder. You will need a 2.0mm/1.5mm hex screwdriver for the disassembly and you’ll want to be 
in a antistatic environment. Some electronics will be exposed during the disassembly and there is 
a chance you could damage them. We recommend not working on a carpeted area and to 
discharge before working. You can do this by touching something metal (Not the printer) for at 
least one second. Wearing an antistatic wrist-wrap would be good. Link for a wrist-wrap here

sr_1_1?ie=UTF8&qid=1494531998&sr=8-1-spons&keywords=anti+wrist+strap&psc=1

 

 
Although, it is highly recommended to use an antistatic wrist-wrap, if you do not have access to 
the antistatic wrist-wrap, you can do the repair process by having a metal contact to your body 
throughout the repair. 
 
Since the M3D PRO 3D printer is highly static device as there are various PCBs involved, if the 
repair process is carried out without following the above recommendation and the customer end 
up frying the electronics, they would need to send back their printers to M3D headquarters for 
replacement. The printer will still be covered under warranty but the replacement units will only be 
send by end of July.  
 

 

Step 1. 

The first step will be to remove the front cover from the Pro. To do this you will need to 

remove the hex screws from the cover. There are a total of 8 screws in each cover. Four screws 
on the top and four screws on the bottom.
