The Transformers series continues to be an inspiration for the maker community with Optimus Prime once more taking centre stage in his original look as a 1:30 scale articulated figure.

Reza Aulia is responsible for this, telling us that this project is a combination of his love for the classic Transformers and making toys.

Optimus Prime was modelled in SketchUp 2016 in a process that took 28 hours to complete – over the course of a week around four hours per day were poured into the design.

All this work was needed to incorporate all the great functionality of this print. Aside from being articulated thanks to several joints throughout, Aulia also wanted it to be printable without supports, available with accessories (Ion Blaster, Energon Axe and Matrix of Leadership), and sliced according to colour.

That last part is especially important as it negates the need to do any painting, as long as you have the correct colours of filament to make it work.

Printing itself took 30 hours with standard PLA and, once assembled, the leader of the Autobots stands 20 centimetres tall.

For finishing work all that was needed here was some super glue to strengthen a few joints, and a clear coat applied directly to the plastic.

You can see Aulia’s version of his own model in the gallery below:

Those inspired by the work done here can make their own using the files which are available for free from MyMiniFactory.

Before you go out and buy the filament or turn on the printers, consider this alternate version made by Patrick Wong.

By changing out the colours for something more menacing, Wong has created a great approximation of Nemesis Prime.

Aside from looking decidedly more villainous, this version is probably easier to print right now for most makers who usually keep a spool of black filament on hand due to its versatility.

Wong’s Nemesis Prime is just about a duplicate of Aulia’s Optimus Prime when it comes to printing: it also took 30 hours to print in PLA and it is also 20 centimetres tall.

If both of these versions have left you a bit disappointed that they can’t transform, make sure to see our previous feature on a single piece 3D print that is able to go into vehicle mode thanks to some clever design work.
