Question 1

How offten does this pen jam and how do you clear it?

Accepted Answer

Hi John, the most common cause of a jam (in any 3d pen) is deformation of the filament. This can be caused by incorrect temperature settings or an irregularity in the filament, and what happens is the heat causes the filament deform so that is not the right size/shape to pass through the pen. Typically this can be resolved by backing out the filament, cutting off the deformed section and continuing. However sometimes, the deformed section pulls off and remains lodged in the nozzle. One of the great things about our pens is that you can pop off the service door, easily remove the nozzle, remove the deformed section of filament and the pen is good as new. The key to avoiding jams is using high quality filament, setting the temperature correctly and most importantly, if the pen stops feeding normally pause your work and back out the filament instead of trying to force it through the pen. Following these tips, you shouldn't ever have jamming issues.

Question 2

How bad is the odor from the filaments?  Daughter with scent allergies.

Accepted Answer

ABS fumes are bad for you. PLA is better, no matter what filament you use you should use it in a well ventilated area. PLA has less of an ordor and is a corn based plastic that is considered safer by 3D print enthusiasts.

Question 3

I want to use a 3d printing wheel filament to use it continuesly but will it rotate the filament as i feed it?

Accepted Answer

The pen will take the filament on its own. As long az you are prezsing the button, it will take the filament. Once you let go of the button, the feed will stop. You dont need to force the pen.

Question 4

once the pen is heated and the abs starts to feed through the pen stops and starts cooling down mid draw causing you to reheat and restart??

An update as we had not seen this question earlier, Robert R had the correct answer. There was an issue with some of the power adapters that were packaged last year where power could momentarily drop on speed settings less than full speed and the pen would return to standby mode. Any 3D Pen Pro sold after March 2019 will not have this issue, and if you have one from last year and see this then please email us at support@mynt3d for a replacement.
