How to Use a 3D Pen

Wondering How to Use a 3D Pen?

We will explain how to use a 3D Pen below. A 3d pen is a handheld unique kind of drawing tool that works like a pencil or pen. It uses ABS or PLA plastic, unlike a normal pen that uses lead or ink. The pen has a powered electric heater that has an extruder and a heating element that melts the ABS or PLA plastic filaments. The ABS or PLA plastic filaments are fed in one end. Once the filaments are melt, they are forced out through the extruder tip as warm thermoplastic that hardens within seconds. A 3d pen has a metal tip that can get as hot as 270 degrees centigrade and has arrows that acts like speed regulators. A 3d pen produces refined three-dimensional shapes which can draw on the surfaces or in the air and requires no computers or software.

How to use a 3d pen
Plug in your 3d pen and give it some seconds to heat up or warm up. Insert the ABS or PLA plastic filaments into the back. Using the arrows, regulate or press the speed of your choice and watch the plastic flow out of the 3d pen through the extruder tip. You can now draw. To switch colors, push both buttons and the plastic ejects out of the back and then slips in another color. The colors doesn’t switch immediately, you need to print out a little bit as the color blend from old to new.

Ways in which a 3d pen can be used
There are many ways in which you can use a 3d pen although they are mostly marketed as artistic devices. 3d pen alone can be used for repair or decorative purposes while in conjunction with the 3d printers, smaller parts can be weld together to make larger models. Some of the creative opportunities with a 3d pen are-:
• Hanging ornaments, jewellery and pendants
• Fridge magnets and decorative art
• Personalization of objects like laptops, pens and iPhone cases
• Basic 3d shapes and models
• A mini Eiffel Tower
• 3Doodles can be shaped as flat forms or peeled off piece of paper.

How to select a 3d pen
There are different types of 3d pen where most of them shadow the same basic design although they all differ slightly in their features. When selecting a 3d pen, it is always vital to consider the following things-:
• Are the speed and temperature settings adjustable
• What kind of filaments can it use
• Availability of accessories
• Cost. The cost does not necessarily indicate the best model

The difference between PLA and ABS filament
When learning how to use a 3d pen, it is good to know the difference between PLA and ABS filaments. PLA filaments are made from starch and are environmental friendly. It has a low melting temperature and a bigger transition temperature. PLA filaments sticks to things well because it’s gummier. Unlike PLA, ABS is stronger and more resistant to chemicals. It is oil based with a high melting temperature but a smaller transition temperature. ABS filaments are expensive compared to PLA filaments although PLA filaments are biodegradable.

How to load a 3d pen
Load the filaments into the back of the 3d pen. Press the main button to start flow and to stop the filaments flow, let go off the main button. Pressing the main buttons at the same time reverses the plastic up letting you to remove it by hand. Loading smaller pieces of plastic helps in angling the pen at 45 degrees. To change the color, you need to add a new color and repeat. To avoid mix of colors, you can opt to doodle a little bit to extrude the remaining plastic in the lower heated part of the pen. color mix may look cool at times.

How the different speeds work
The 3d pen has two main speeds which are fast and slow. The speed determines the flow of plastic allowing you to delicate or intricate details at your own pace. Switching between the different speeds can be done by pressing down on the lower or upper doodle buttons on the body of the pen.

How to maintain a 3d pen
Maintaining a 3d pen does not require much. If there is trouble with plastics coming out of the pen, wait for the pen to cool down and rub it with a cloth soaked in rubbing alcohol. To avoid the risk of breaking your pen, never force anything into place. Apply downward pressure on the maintenance cover whenever you are inserting or removing the metal bar. Make sure there isn’t plastic inside the pen whenever you are putting the maintenance cover back and reinsert the metal bar the right way up. Always change the nozzle while the pen is hot and use nozzle remover tool to carefully unscrew the nozzle counter-clockwise.

Difference between a 3d pen and an ordinary pen
A 3d pen looks sort of an ordinary pen but its size is quite big. The ordinary pen uses lead or ink while a 3d pen uses plastic filaments. A 3d pen has an in-built fan and an electric plug. The purpose of the fan is to prevent the pen from overheating. There is a power switch on the side of the pen. The switch is a plastic selector and not a simple on and off button. When the pen is off, the button is in the middle position. Speed controllers are at one side of the pen’s bottom while the other side have the 3d’s mount. The tip of the 3d pen is everything (it is the soul and heart of the pen), it comes with a removable rubber protector.

Facts about 3d pen
• 3d pen has thousands of uses
• 3d pen is eco-friendly
• 3d pen isn’t a toy
• Using a 3d pen does not require know-how
• It is fast

The pros of a 3d pen

• It gives freedom to create 3d objects freehand
• No need of computers or software
• It has the ability to switch between the PLA and ABS plastic
• It is portable for it is small and light in weight
• Allows instant vertical drawings
• It has a unique cooling system that cools plastic very fast
• Some has auto-standby mode
• Drawing and writing in the air is possible with a 3d pen

Cons of a 3d pen
• The pen can get to high temperatures which can be hazardous if any part of the body comes into contact with the nozzle
• Continuous tweaking is need for extruding temperature
• Issues of overheating in the pen’s physical body
• The hot end tip can break if tightened too much
