When I picked up the Sunlu 3D Pen (CCbetter 3D Pen) for the first time, I immediately noticed the low weight of the pen. Also, thanks to the rubberized surface and its shape, which is suitable for both left-handed and right-handed, it is very good in the hand. Although the pencil looks a bit clunky, but also children should cope well with it.
On the side, on both sides, the pen has several function keys. On the left side there are the pull-in buttons with which you can pull the filament into the pen or pull it out. The speed buttons are on the right. This controls how fast the filament is pulled out of the pen. On the top there is a small display, which you can use to select the filament type (PLA or ABS), as well as the temperature of the pen. On the back we have the socket for the mains connection and the opening into which the filament is inserted. My first impression was very positive and I could well imagine being able to draw something with this pen.
As soon as you connect the pen to the power supply, the pen is switched on. There is no separate power button. However, you don't have to worry here, because only when filament is inserted and the filament type has been selected does the print pen start to heat up.
Here 2 rolls of PLA filament were added. PLA differs from ABS in that it does not have to be heated too much and is also biodegradable. ABS, on the other hand, is more stable than PLA and is therefore suitable for machine parts that are more likely to be printed with a real 3D printer. When you insert the filament and press the feed button, the pen slowly heats up to around 170 ° C. The temperature can be seen on the display.
After a first test run, you got used to the pen fairly quickly. Drawing with the Sunlu 3D Printer pen is similar to drawing the 3Doodler. In my first attempt, I traced a butterfly. There are templates for this in the net, whereby creativity knows no bounds. The filament is applied freely at will and connects without problems with the already dried filament parts.
That the pen is hot and you could burn, I have not found. Also, the filament cools down pretty quickly and is also very fast hard. Nevertheless, one should not underestimate the pen. Especially the small white tip of the pen is very hot and should not be touched.
