After Doodling the first initial of his or her name, students will successfully reverse the strand from
the pen by pressing both extrusion buttons simultaneously. Once the strand is no longer moving
out of the pen, pull it clear of the 3Doodler and trim the melted end so that is clean and ready to
be used again as shown below.
Note: Reinserting the melted end of a strand of plastic may result in blockages and/or damage to
your 3Doodler.
