3D Build N Play 1
REVIEW – I am a major 3D printing fan, and I own four 3D printers and would love to own more. I have printed so many things including toys for the kids that they too have become fans of 3D printing. The problem is that they want to tinker and print for themselves and at their ages, I cannot let them get near to my printers!! So what do I do? Enter the 3Doodler 3D Build & Play 3D Printing Pen.

What is it?

The 3Doodler Build & Play 3D Printing Pen is designed for kids 4 years and older and includes special molds to allow kids to create designs, some of which follow read-along stories. It is designed to promote STEM learning for kids. 3D Build and Play is compatible with all kid-safe 3Doodler Eco-Plastic.

What’s in the box

On the top front there is the nozzle where the plastic comes out and at the top back is the hole where the plastic is fed into the 3D Pen.

On each side, there is the insert for the crank handle and marking to show the direction in which the crank handle should be turned to extrude or retrieve the plastic. The handle can be used on either side to accommodate left-handed and right-handed users.

To get started, you have to install batteries.

There is an accompanying app that brings the creative process to life.

My kids had a lot of fun using the pen.

Here are some samples of the resulting models that my kids created:

What I like

  • The simplicity of the design
  • The ease of making the models
  • The fun and imagination it provides for kids

What I’d change

  • I would like the mold to be a bit stiffer and to be able to make the models a bit thicker
  • While I can find plastic refills on their website, I could not find additional molds. If I am correct then more molds offering more printing options should be made available.

Final thoughts

The 3Doodler 3D Printing Pen is a nice toy for kids who want to explore the concept of 3D printing at an early age and get a good idea of what they can create with their imagination. In my opinion, for the price, it is a good deal.

Price: $29.99
