3D Printing at the SMS: 3D Pen Tool

3D pen tools at the SMS

The concept of a 3D pen is similar to a glue gun in that material is loaded into it and, once melted, it is extruded and manually applied. 3D pen tools have been promoted as a great way to draw freehand, as well as trace designs in 3D. Our favorite example of tracing so far is the Eiffel Tower project. Using a template design from the 3Doodler website, our student traced the tower outline with the pen, then assembled and fused the model together using the pen and filament.

The pens are a compliment to our 3D printing service and can be used to repair or embellish upon 3D printed models. Our pens use the same filament as our Makerbot Replicator 2x printer so we are able to color match and, depending on the model, produce seamless repairs.

Our 3D pens are freely available for use by Kent State students. See our "Policies" section below for more information.

FAQ's

What is a 3D pen?

 A 3D pen is like a handheld 3D printer but there is no program necessary – just your imagination and a little practice.

How does it work?

Just like the 3D printer it pulls in the plastic filament, heats it up and extrudes it out like a hot glue gun. The plastic cools rapidly which allows you to build forms. Depending on the device, it may either use ABS, PLA or both.

What can you do with it?

  • Draw straight up in the air

  • Build 3D forms out of plastic

  • Trace images on paper

  • Weld pieces of plastic together to enhance or repair things

  • Enhance a 3D printed model

Are 3D pens expensive?

Unlike a 3D printer that can cost in the thousands of dollars, a pen is only about $100.

Is the material expensive?an image of ABS plastic filament for the 3D printer

Some 3D pen tools such as the 3Doodler will only work with their proprietary material, which can be expensive. The pens in the SMS, along with many other pen tools, can use either ABS or PLA filament that works with our 3D printers.  The ABS filament can range from about $40 for standard colors to $130 for specialized materials like glow-in-the-dark. Filament is sold in 750g-1kg spools (which goes a LONG way!)

Policies and procedures

Before your first project

We ask that you arrange an appointment with an SMS consultant to go through a brief training session in order to learn the ins and outs of the 3D pen tools. Once we feel that you show a reasonable proficiency with the tool you will be permitted to use the pen on your own project. You only need to complete training once before having access to the pens. Contact us at KentStateSMS@gmail.com to set up an appointment!

Working on your own project

Stop in to use the pen during our regular SMS hours. While we do not currently require users to reserve a pen in advance it is advisable to call or email ahead of your arrival to make sure that a pen is available. Due to the quirks of the pen tools and potential for injury (hot nozzle tip) we prefer that a consultant work alongside you. The pens sometimes need tinkering in order for them to work properly. We hope to eventually have this process streamlined soon (and more quirks worked out on the pens!). Thanks for your patience as we make adjustments along the way!

Under development

As we are in the pilot phase of offering use of the 3D pen tools, our policies and procedures will be subject to change. Your use of the tools will help us further develop the service. Thanks in advance for your patience and understanding!

Please note that we reserve the right to decline use of the 3D pens for any reason.
