Recently, @Dizzie created a thread about going to a Con and meeting Brian Paone, author and owner of one of those beautiful movie-accurate DeLorean conversions:

Check out his site here:

I don't have 100 grand lying around, but this inspired me to do the next best thing: 3D print my own.

Months ago, I purchased a printable DeLorean time machine model from a site called GamBody. Life happened, and like many things in life that project got shuffled to the back of the queue. Today, though, Cosmo emerges from the chaos of life in 2022 to wield this project with skill and great success. You're welcome.


There are a few other variations - One for Part II with Mr. Fusion and the hover conversion, and another for Part III with the 1950s tech and white-wall tires. I'll tackle all of those, but we'll start with the original first. We'll build all variations, along with the Jules Verne Train. There's another H.G. Wells style time machine out there that I may consider doing too,

These will be given away afterward, to help promote the site and give one of our members something awesome to display in their home. But you have to love it, and send photos.




I'm printing on a Prusa i3 Mk3 that I built from a kit in summer of 2020. or 2019. These are GREAT machines and highly recommended. There are less expensive options for sure, but the heated printing bed is something I couldn't live without because it prevents "warping", especially helpful in big prints (helps avoid warping).


After downloading the model files, I'm presented with about 110 different files:


Each of these files is a single component of the DeLorean, which must be "sliced" into instructions the 3D printer can interpret. This step is where things like layer height, infill, retraction speed and other settings come into play and there's a lot of flexibility here. Getting a good print depends as much on the model as it does your settings, so a few prints will always be a required sacrifice to the print gods.


Many materials can be used in a printer like this - I'm using PLA which is inexpensive and easy to print, but it's brittle. If this was a toy or something meant to be handled, I'd probably use ABS or PETG. ABS is more durable, but hard to print and needs ventilation (I'm printing in my living room with small children and pets). PETG is a sort of middle-ground, and I'll be using that in an upcoming full-sized, remote-controlled Astromech build.


I've got some Ninjaflex filament around here somewhere, so we can give the DeLorean real rubber tires. ;)

For this bad boy, we're printing most parts at 20% infill with a layer height of .1. All of that is to say, we're doing our best to get the best quality and smoothest finish so there's as little post-processing as possible. I'm lazy like that, and "look at my sanding" isn't an update I care to post.

Once the object has been sliced, the exported file is sent to an OctoPi server I run on a little old Raspberry Pi I had lying around:


This basically lets me log into a webpage, upload a file from down here in the TTI lab and start/monitor the print without having to run up and down the stairs. I live in a townhouse. My house is made out of stairs.


I found a way I might be able to livestream 3D prints to our other channel (Curious Cosmos). If I can get that figured out I'll leave that running as close to 24/7 on a print or our tortoise or some other thing.

Last night, I began a print of 980-1-bl_1_bumper_b, which feels like the back bumper. It turned out great, and the overhang supports came off nice and clean. It was followed earlier this morning by its little brother, and was followed shortly after by it's little brother, 980-2-bl_2_bumper_b_grid.






I'll continue posting more updates as more batches of parts are completed, then I'll attempt to paint this during a future livestream.
