Soyuz TMA-3
This is my first post and my first attempt at building a 3D printed rocket. Found the files on thingiverse website. Thought it would go together easily, but so far have spent several weeks modifying pieces. Some of the files didn't apply and others printed at the wrong scale. Will use F or G motors for power. Requires plenty of sanding to remove the filament lines and it is heavier than I expected.

Slick. I'll be interested in hearing how it flies.

Cool, this looks great! What plastic filament material did you use, and what model of 3D printer?

Thanks. I'm told it was abs plastic on a Stratasys Fortus 250mc printer.

You are very lucky to own or have access to a $45,000+ 3D printer; over 250 times the price of the Creality Ender 2 that I own. Even the ABS filament for the Fortus 250MC costs over $100 per kilo, that is about 10X the cost for the materials I use for 3D printing!

I had some free time over the holidays and was able to make some progress on the Soyuz.
The motor mount is finished and the boosters have all been fitted. I added some detail to the nozzles and finished beveling the fins. A little bodywork and I'll be ready for the paint booth. |

How big is it?

One meter tall. I considered your comment about the wire nut nozzles being heavy and have since cut them off nearly flush on the reverse side. They now weigh 0.5 ounce each including the fin. I ground a lot of plastic out of the boosters trying to reduce weight on the aft end. They were printed to accept a 13mm motor in each one. They are now completely hollow. I thought about replacing the center section with a cardboard tube but there was no significant weight savings. The issue will be how much I will have to add to get it balanced correctly.

Construction continues with a cord mount made from birch ply that is coated with JB Weld on the underside for extra heat resistance. A few more external details were fabricated and attached near the top. Hopefully I will get some components painted over the weekend.

Painting is now underway. The colors are a good match to the photos I've been working from. The nozzles have been the only difficulty. I used chrome paint and it looked great until about 4 minutes later when it all wrinkled up and lifted. I now face the tedious task of trying to remove as much of it as I can before attempting to repaint.
