What is a 3D Pen & Are 3D Pens Worth It?

Most people have heard of 3D printers, but 3D pens are a whole different tool that aren’t very well known. I wondered this myself when I first heard about a 3D pen, so I set out to find out exactly what a 3D pen is and whether they are worth it.

A 3D pen is a small tool in the shape of a pen which pushes plastic through a heated system to melt it, then extrudes it through a nozzle at the tip of the pen. The plastic hardens almost instantly and can be used to make basic or complex shapes and models. It can use PLA, ABS, Nylon, Wood and even flexible materials. 

That is the basic answer which gives you a quick idea of what a 3D pen is, but the rest of this article will go into some interesting and useful details about 3D pens, as well as 3 of the best 3D pens that are out on the market right now.

What is 3D Pen

A 3D pen is a handheld tool which allows you to insert a roll of thin plastic (PLA, ABS & more) into it, melt the plastic within the device, then extrude it layer by layer to create cool 3D objects.

They work similarly to a 3D printer, but they are a lot less complicated and much cheaper.

There are many brands of 3D pens that are aimed at professionals, children, artists and even designers for fashion. A 3D pen can really bring your thoughts and ideas to life in a very quick fashion.

It seems like magic at first, but after you get the hang of it, you realize how cool and useful they can really be. Whether you need an entertaining and creative way to occupy kids, or want to join up two pieces of broken plastic together, it is pretty versatile.

There are fashion designers who have actually made clothing directly from a 3D pen which is really cool.

How Do You Draw With a 3D Pen?

The video below shows sweet illustrations of how to draw using a 3D pen. They work quite similarly to a hot glue gun but instead of pushing hot glue out, you get a plastic which hardens pretty quickly.

The usual method to draw with a 3D pen is to draw the basic outline of a model then fill it in with the 3D pen. After you have the foundation, you can add more of a 3D structure to it.

What Do People Use 3D Pens For?

3D pens are great for a number of things, but being a supplement for your 3D printed models is one of these uses. when your models have gaps or crevices which need to be filled, then a 3D pen can be used to do so.

It can also join together a broken piece from a model. Once you add melted filament to your model, it would look like a blob and quite low quality. What you can then do is sand that melted filament down after it hardens to smooth over the surface.

Some areas are just hard to reach, so having a 3D pen in your arsenal can be very useful.

3D pens are a great help for artists who specialize in 3D objects as well as crafty work. Artists can create pretty intricate designs with a professional 3D pen and a good amount of experience.

They can make small sculptures as well as prototypes. This rapid prototyping method is an amazing way to show other people your ideas in real life, rather than just being a thought.

There are many 3D pens designed for educational purposes and entertainment for children, where they can have some type of workshop creating 3D objects. Kids can experiment and really bring out their creativity with a 3D pen.

The following professionals have been known to use a 3D pen in some instances:
