CoLiDo 3D Pen: Maximize Safety in 3D Printing Pen

The stylish CoLiDo 3D Pen maximizes the SAFETY in use. Everyone can handle the pen easily and let your drawing stand.


3D printing devices which using FDM technology are inevitably to have very hot nozzle. It is a threat to users. We are now launching a new 3D Pen and improve it safety by using a auto-retract nozzle. Together with CoLiDo’s strengths in 3D printer and filament, the CoLiDo 3D Pen let you draw your 3D model easily and safely.  

Beyond 2D
CoLiDo 3D Pen has revolutionized the concept of a simple 2D drawing. With a CoLiDo 3D Pen, now your drawing has 3 dimensions. What you draw is a solid object that is not just on a piece of paper anymore, but literally stands on any surface when used.

Beyond Location
No matter whether you are in school, office, party, coffee shop, etc., you can make your own 3D creation with this small and portable CoLiDo 3D Pen.

Why CoLiDo 3D Pen?

Portable 3D Model Creation Tool
+ Portable and pen-shaped.
+ Weighs only 70 grams. Easy to carry around.
+ Fast/Slow mode options to facilitate your 3D model creation

Create High Quality 3D Models
+ Specially designed print-head to squeeze out filament smoothly
+ Keeps print-head temperature stable through PID controller to prevent filament cut off

Choose from a Wide Range for High Quality Filaments
+ The filament is made of high quality material, which helps create better 3D models
+ Choice of many filament colors and texture

+ The print-head slide up inside the 3D Pen when not in use (e.g. feeding filament)
+ The pen enter Sleep Mode when it stops being squeezed for 5 minutes or more
+ The pen enter Sleep Mode when the print-head temperature is higher than 250°C (482°F) or lower than 1°C (33.8°F)


+ Conceptual drawing
+ Personalized gift
+ Decoration and display
+ Tool for work and daily life
+ etc….

Risks and challenges

We are experienced in manufacturing FDM 3D printer. We believe in our 3D Pen quality since we have applied our 3D printer technique to the 3D Pen. But there are still some risks and challenges which come from the limitation of FDM technology.

Due to the limit of FDM technology, the nozzle of the 3D Pen is very hot during operation. The auto-retract nozzle of CoLiDo 3D Pen can reduce the chance of accidentally touching the nozzle, it is not 100% safe to all users.

Surroundings temperature will affect the function of the nozzle of CoLiDo 3D Pen, e.g. the movement of nozzle and the filament flow inside the nozzle. But according to our tests, the 3D Pen will only be affected under extreme temperature. It works well in room temperature.

One challenge is about letting everyone in the world know CoLiDo 3D Pen. We hope everyone can learn and enjoy 3D printing and creation. But the world is very big and we cannot ensure our products to reach all people. Support from backers, either through sponsoring or simply forward our messages to others, are important for us to promote 3D printing to the whole world.
