Rogue One Shoretrooper - Droid Built!


Recommended Posts

So it's been a while since I've built anything - I got hit by a car while riding home from work and sadly my left hand was pretty badly broken, crushed little finger, 4 out of 5 metacarple broken! the hand was in a pretty bad way and I was sporting more metal in my left hand than a Skywalker! 


So i'm well on the mend now with 4 sessions a week of physiotherapy and to get my mojo back I bought a Prusa i3 MK2s kit with the full intention of putting it to good use! The original plan was to build either a 1st Order Stormtrooper or a Death Trooper but having seen Sean Feild's amazing 3D files I decided to build this. 


So first of all, Thank you Sean for these files, utterly utterly beautiful!

So first the 3-D Printer - this is an official Prusa i3 Mk2s kit build, yes I know there are clones for cheaper but as I was new to this I wanted and needed any support from a dedicated community. Obviously I got the black edition - it's an imperial droid after all!




So I decided that I would print off the small detail parts first to get a feel for the printer - after reading several forums and talking to a few people that 3D print for a profession I decided to use PETG for the build.


The greeblie came out perfectly so I then decided to move on to the more complex snout.




So far so good! (everything dry fitted nothing bonded)

The next run was on the central helmet dome - this was a pretty long print and so I set up the printer to start early Friday morning and finish Saturday at some point - I still hadn't found out there was a stealth mode (Silent) and the wife was getting a bit annoyed with its constant whirling and chirping - the vibration noise was the main issue though!



Sean's files are something else and this printed without any support structures -however the next print which was the cap dome sides would need some support structures in place.

Using the Prusa Control software it was just a simple button click away! I decided to print both sides at the same time as this would save time but risky if it misprinted!


A very long wait later!


As you can see the support structures were needed.



These just tear off leaving a very clean finish.



Some more dry fitting to make sure there was no warping.

Next up was the Blast shield mount and the shield itself - I got my first misprint after my mother in-law decided to touch it while it was running! So I stopped the run, cleaned it all off tossed the PETG waste in the recycle bin and started again!








I also got some chemical bond that welds PETG together - much stronger than a glue.






Sunday 28th I had a marathon in Shonan City near Yokohama and just before I headed out the door I put another print on - this time the back section of the helmet and the back rim. This is another nice technical part that required some support structure.


These again are dry fitted to see if they meet up correctly and then bonded.

So that brings us up to today.

I'm currently printing both the left and right sidewalls - here it has just at 6% and laying the foundations and the supporting structure.




when I left the house this morning they were 96% complete



Once I get home I'll start the cheek pieces, i'm not sure if I should do these separately or double up again.

Thanks for posting this,  I've seen 3d printed armour but its good seeing the actual printing process.

How complicated was your printer to setup? 


I think if your building your own armour then building the Prusa i3 MK2s or 3 kit is going to be easy. The only advice I would offer is that you take your time building the Y-Axis, that’s where tolerances are important so having a very good set of measuring calipers and checking everything twice; especially then tightening the nuts then you’ll be laughing - the instructions are very easy to follow so really I can’t see how anything could be out.

So last night I got home from work to find the base side walls complete. Nice clean prints however they are going to need some post production work - so I’ll be making so PETG putty later this week to hide the join lines and a few of the gaps, nothing major and to be expected on a large curved surface that’s broken in to parts.








As soon as the print bed was cleaned off and prepared I set the printer off again to build the left and right cheek parts.


At 5:00am this morning it was at 30% complete so it might be finished tonight when i get home. From there it will be on to the mask which will test the Z-Axis to

its limits I think.

What layer height are you printing at? Looks super fine!

The Print settings are as follows:


Materials: Prusa PETG

Quality: Detail - 0.1mm

Infill: Standard -20%
Support: Part dependant

So the left and right cheek parts failed, due to my wife trying to move it for some reason. So I decided that it was best to print them separately as it would be faster and safer. 


I used the downtime to check the recalibration of the XYZ axis, unfortunately it seems that she twisted it when she picked up so and slightly twisted the axis - that was easily solved by loosening the Y-axis putting it on a perfect flat surface and retightening everything.


so with all the recalibration done it was back to printing!








Dry fitting - the tolerances are very 




So with it bonded it was time to see how it was looking!!

I am also working on a 3D printed Shoretrooper (though with different files), I am curious if you have though about the shin/lower leg armor yet? I am worried that the PLA will not flex enough to allow my foot to slide through. 

To be honest for Trooping I would go PETG not PLA - a lot of the Japanese costume makers and cosplayers here use it- as for fitting I have a feeling it's going to need a creative cut. some where and a form of binding to close it.

Right now I'm focused on the helmet, the front face plate is a nightmare to print and I've basically put that aside till last as 5 print fails started to test my patience.

So this weekend I had big plans on getting the build of the helmet finished - sadly the printer had other ideas!


So first thing was to chemically weld the parts of the lower helmet together using PETG putty - using the support structure and the nasty chemical stuff I melted down the PETG in a glass Tamiya bottle - I know the plastic they use doesn't seem to react to anything nasty so I knew I was safe with them.



This I painted all over the joins making sure that it went in between the cracks and that it had a pretty good coat height ready for it to be sanded down.


I left it for a few hours outside to let the vapors vent off and then went at it with the electric sander.


A few areas that will need filling are gloss black but with a few coats of primer and sanding back they won't be visible.



I'm tempted to paint the chemical over the top of the sanded area to bring back the black gloss, however as this will be primed there is little point.

So while I was letting the putty cure I was back on the printer making the face plate and this is where things started to get tricky!

This file my printer REALLY didn't like !After 5 attempts with different speeds- support material setups I decided to stop and see if it was the printer or the file.

With standard pillar support

With Sean's modified file

Both resulting in either a misprint or the actual print snapping off due to a weak support frame! This is going to need more research and I'd be interested to know what settings others used to print this part.

So with these fails I decided to clean and check the print nozzle as I was getting irregular filament flow and heavy stringing. With that done I went about printing the upper side walls.

I started at a 30% print speed to lay the foundation and first few layers and then sped up the print by 10% increments after each 10% of the file was complete and checked on the progress for misprinting or other issues - Once It had reached 100% speed I decided to see if it could handle a bigger work load and increased it to 110% which it obliged happily although after the failures of the morning I brought it back to 100%.


No printing problems so far!


DONE! All of the supporting structure happily peeled away revealing the first of the upper side walls!




A bit of dry fitting to see how it looks and if there is any warping of the materials - PETG is really good at retaining its shape and one of the reasons why its widely used by Cosplayers here in Japan.



So my little Imperial Printer Droid seemed eager to get on so I fired up the opposite side and set it to work - again at a 30% print speed for the foundations and then once the first few layers of the main structure were down I brought the settings straight up to 100%

So I came home from work to a completed left side so after cleaning off all of the supporting materials I first bonded them together and then once it had cured filled in the seam line.





Again once this was done I used the electric sander to smooth down the weld and then switched to a sanding block.


There was only one job left to do and which was to clean up the print bed and set the printer into motion again - During the early stages of the print the left corner of the brow started to peel off the bed, this was saved by pausing the print and then using some Pritt Stick glue under the print using a tooth pick and then rebonding it to the print bed.


So this morning a quick tidy up of the new parts and then everything bonded.


Time for a little dry fitting to make sure the build is properly aligned and no warping has taken place.



Ohhhhhh yes!


So with everything looking like it sits perfectly I've set the printer going on 2 of the last of 3 parts - Those should be ready when I get home tonight.

FYI, this is a great build, keep it coming! However, it's worth noting that this forum is specifically for the Rogue One Stormtrooper and not the Shoretrooper. There's a few threads on here that need to be cleaned up imo. I'd advise taking the build thread over to the Pathfinders Detachment Forums, where they're the ones who currently hold the Shoretrooper CRL :)

So Wednesday night I get home to a print that I doubled up on, The eyebags and the brow - very clean print for the brow but the eye bags needed a little post work to get them nice and smooth.


Maybe a little more work needs doing but I'll address that once the helmet is built.

Now it was time to return to the front face plate that had been giving me some grief, more misprints than I can remember so I changed the print detail from ultra detail (0.05mm) to Optimal (0.15mm) layer height and a print speed of 30% This seemed to do the job and when I got home I was very pleased with the results.

No misprints or problems so I decided to up the print speed to 50% - BAD MOVE
you can actually see where it goes wrong, however it does not seem to have effected the overall build, yes there will be a lot more post production work required but if the nose and nose bridge are ok then I think the rest will be just a case of sanding smooth. I will see once I get home today!

If not then it will be a long drag at 30% print speed.



I'm hoping its usable as that will be the helmet complete and I can start bonding and preparing for paint this weekend!

So I came home with some trepidation today knowing that there was a high possibility that the print had failed - so I went and walked the dog before checking on the print. :lol:

Thankfully there wasn't a hot mess of PETG on the floor or a burning crater where the printer once lived but what looked like a part that could actually be used!


With a bit of clean up using a sander, snips, and files I had a very usable part indeed!


Time for some fun!









So I had to get a bit creative with how to clamp the dome on to the lower section of the helmet.

Morning all - Well fabrication of parts is complete and they are bonded together.


What I would like is some peer review at this point to see where I need to work on the helmet to bring it up to spec for the 501st. Then I can make those changes and then paint. There are gaps and seem lines that need attention however those will be addressed once any changes that need doing are dealt with,

All critique is welcome!

Another busy weekend - both on the build and also making stuff for work and the kids!

The first task was to give the helmet a coat of primer - this is more as an indicator for areas that need sanding or filler



After a very dusty 2 hours I applied the filler and left to cure.



The next morning I was back at it and happy with the results.


Also another shipment of filament and some nice hardened steel nozzles arrived. The printer was also set to task on the chest plate.



With the grey primer down again I decided to add some black - instantly some of the other imperfections and notable areas jumped out at me - I think I will buy black primer in future as it solves a lot of time!




So again it was back to sanding and filling!



With all this going on the Chest Plate completed its run and a small nightmare occurred.



The wires to the heating element had come away! A Quick message session with Prusa sorted everything out and I also took the time to buy a few spare for future hardware failures.

So.....I finally finished sanding and priming the helmet and put down a coat of flat black Mr. Hobby 500 grade primer. I use this extensively for some of the professional work I do as its incredibly hard wearing. 










So this afternoon I will then spray a coat of flat black paint and let it cure and then apply a flat clear coat. Sadly there isn't a lot I can do now until I get the printer running again or the test samples for the paint arrive.

This is coming out really well, you've done a great job!


I am also doing this build, I still have to print the dome sections but I am out of black filament at the moment.  The face was a tricky part but I got there in the end.  I used the unsupported file and then used the support generated in Slic3r PE.  My biggest issue was the rear bottom edge didn't print cleanly so I am hiving to re-build it with filler, I need to get some bondo for it.


If you've not done it already I recommend using the 3.1.0 firmware with Linear Advance, even on slower prints the better corners are worth it.
