About us

Dollo 3D - Father and Son

father and son

We are 3D printing fanatics

We are the father and son team of Ben Engel (I) and Benjamin Engel (II)

About 5 years ago, we decided to try 3D printing. We had long been inspired by the vision of the reprap project, where the goal was to evolve more self replicating machines. Benjamin (the son), built a reprap i2 Prusa Mendel. And our household has never been the same since.

Since then, we have built a 2 more repraps and a filastruder and have helped friends build reprap printers. We particiate in our local Southern Utah Makerspace and really enjoy advocating for the 3D printer movement.

Evolving Reprap

Since commercial products have expoited the reprap movement, we were sad to see that printers are not being devloped for self replication any more. While this is great for people that want a consumer product that "just works", it also stunts the creative development of the reprap vision.

Why don't you 3D print a 3D printer?'

It seems that whenever we tell people, especially young people about 3D printing, they usually ask "Why don't you 3D print a 3D printer?". We then explain the reprap project. It then becomes painfully clear that we really need new evolution in self replication.

Startup Weekend! The picture above was taken of us at Startup Weekend in St. George, Utah where we started our dollo.org, a online community for creators to connect with designers and makers.

We are planning a kickstarter!

This has been a work of passion, but we are not ready to share it quite yet. We would like to invite you to sign up for our newsletter where we will let everyone know when the kickstarter is launched and when our models are complete

Eddie Krassenstein must have done some digging because he found our scad files on github while we were still operating in silence. We were delighted to have him let the cat out of the bag.
