Project tinkerbell

Welcome to the MMU Bravo one

Mobile Maker Unit - Nano factory

The mission with the MMU is to create a fully operational Nano factory that turns local plastic waste into fully functional parts and products. We started to design the MMU as project Tinkerbell back in early 2020, but we are now ready to showcase some 3D renderings that show the features and plans with the Mobile Maker Unit.

A mobile 3D printing factory inside a 20' container

We wanted to re-use shipping containers, they are great for keeping equipment safe, easy to ship over oceans, structurally sound to build inside and it's a nice mix of blade runner and Mad Max.
FDM 3D printers inside

The MMU is equipped with 18 FDM 3D printers that work in parallell. They can work 24/7 and both off grid and connected to the grid. They consumer very little energy once they are running and with 18 printers we can produce locally needed parts fast.

Uses recycled materials

The MMU is based on using recycled materials like rPLA and rPETG. It can also recycle local waste into material for injection moulding or 3D printing. It will be equipped with shredders, injection moulds and 3D material making machines.

Connected to

Connected to the mobile internet and the parts database are available to all MMU's, this allows for external 3D designers and engineers to remotely build 3D designs.

Zero carbon

powered by our star

If we say circular, we mean it. We use the closest star to power our MMU, often called the sun.
Sun power

From the five sun panels we can generate around 1500 Watts on a sunny day. What is not used we store in a powerful battery, so we have backup power during the night for long 3D prints.

On - Off grid

If we have electricity we can run the MMU with higher capacity and multiple functions at the same time. The aim is to enable the Nano factory to function off grid, but if we have electricity it is a bonus to secure 24/7 operation.

Power Outage

The system is designed to regain full operation if all power is gone, with bad weather and long dark nights, we still can resume printing when power is back...

climate control

We have to control the temperature in the MMU as well as the humidity level, that is a challenge depending on where the unit is shipped and setup for operation.

Cooling or heating the unit will be essential. We are working on recycled and 3D printed insulation panels and boards, together with researchers and industry professionals. All building materials should be recycled materials from wood, plastic or other materials.


We will have a drying cabinet for storing opened 3D materials that are hydroscopic and will absorb moisture typically like PET plastic. Vacuum boxes and drying cabinets will be part of the inside cabinets to protect the material and allow for great quality prints

Solar powered

The system will use smart controls to think ahead how to use the available energy at the best possible way. This means power, solar, battery backup, air-con and recovery systems will work in harmony to conserve the energy and preload cabinets during the day and conserve power during the night.
