First attempt at 3-D printing
GroupBfan Tue Feb 09, 2021 6:39 am
I was quite fond of my Norev/Provence Moulage/Luminyo Nissan GTi-R from the '91 Safari until I realized that they had put the entirely wrong wheels on it.
Try as I might, I couldn't find a suitable replacement set, so I had no choice but to make my own. I removed the original wheels, took careful measurements, and then modeled the replacements (which are I believe a bespoke version of OZ Superturismo wheels specifically made for Nissan) in a 3D package called Modo (which conveniently I use in my job.)
I printed them using the SLA resin printer we also happened to have at work, and here are the results. Sadly a lot of fine detail is lost due to the resolution limitations of the printer, but I'm hoping to take another stab at them when we get more up-to-date equipment. But for this scale, they'll do fine.
Had to cut two of them to fit as spares, which was very tricky as 3D print resin is extremely brittle.
End result is pretty satisfactory. Still have to blacken the wheel centers but it'll do.
Next project will be a more ambitious one, I'm modeling a 5-door body to fit Maxichamps' Alfa Romeo Alfasud TI (3-door) model. Going to need a sharper 3D printer to make that happen though. We'll see how that goes!!

Very good, how did you find them to finish? I had some 3d printing done on a half scale tractor and found sanding etc very difficult

Thanks, guys. I'm looking forward to doing more when I get access to a printer again.
I didn't really have to do much. What you see in the photos is how they came out, and it only took a minor sanding pass to prep them for primer. The SLR prints come out a lot finer than FDM, and you generally don't have to deal with much "stair-stepping." That said, I'd hate to print something 1/2 scale with it, printing time doubles each time you halve the z-axis resolution.
