Tips
  • If the pen is straining to extrude, raise the temperature.
  • If the pen is oozing filament uncontrollably, lower the temperature.
  • Only load and unload filament when the pen is heated to temperature
  • After extruding, lightly tap the nozzle on the print to avoid stringing.
  • Use a finger to  pat down on a freshly printed area to smooth it.
  • Handy tools to have
    • Pointy tweezers to remove bits of filament from the nozzle
    • Diagonal wire cutter pliers to make the end of the filament clean for inserting into pen
    • Third hand clamp for holding printed object
  • Practical uses:
    • Repair prints made with a 3D printer
    • Use like a hot-glue gun for repairing household objects: joining objects, patching holes
Review
Pros:
  • Temperature is adjustable to a specific  degree.
  • USB cable allows for flexible power options (e.g. portable power source).
  • Pen functions well.
Cons:
  • It’s difficult to avoid pressing the speed buttons when pressing the extrude button.
  • Holding the pen is a little uncomfortable.
  • Two meters of 3 colors of filament isn’t enough to make very much,  yet is very inexpensive (around $0.08 USD per meter).
  • The included stencils aren’t very good.
Recommendation

This 3D pen functions well. The ergonomics could be better, specifically the button placement. Having the adjustable temperature would justify its selection among low-priced 3D pens.
