SIlverTriple's 3D printing stuff... 2 months 1 week ago #74743

Beside the Samurai, my Ninjas as well need tires...






The print have the same issue than the Samurai... And from the discussion I got in a french forum related to 3D Printers earlier today, it may come from a suction cup issue. I've added a hole in the slicing next to the the plate in each tire and relaunched a print to validate if it is actually this or not...
Anycubic snet me a file to print without even taking care about the exposure time needed for the resine I use (I may be a bit off the standards, here :-) )
I buy kits to built and ru(i)n them :-)

These spikes are interesting.  Better than the micro spikes used actually. They should be awesome with the dt03.

With a hole on the tire thread placed near the bed, no issue anymore.

In short : only remains eventually to test alternate rubber resin to identify the best one for this application. I've printed near perfect tires last night (just remains some traces left by the supports), and I'll get them running as soon as possible... I may try to find other resins with even lower shore, but this test is already much better than a FDM TPU print.

My process may not be optimal in terms of resin consumption, I've printed about 10 tires already, a set of two Samurai tires are in progress as well. and it should make for 12, with one kilogram of resin, and this can probably be optimised further (remember I'm a full newbie in SLA resin 3D printing)...

Last night, I launched a long print (ok, ot so long, it would have taken much more time on the E5+)...



The Big Bear / Super Wheelie 3 part chassis for dimensional test... Next will be in the Super Wheelie and Big Bear thread (later this afternoon, I won't have any time this morning)...

I've identified and ordered some different flexible resins with lower shore than the one I already used. One of them is even translucent and can be colored. I should be able to do more testing soon on tires topic :)

Beside this, while searching for those, I identified other resins with interesting properties for other applications. The resin finish (with proper post processing) is better than any FDM print (and even than Nylon PA12 MJF prints), and that gives some interesting case for the future. I still have some doubts about HDT and how this results in real usage, but that could make it for nice and strong technical parts... Further tests to come in the future :-)

One of the issues I have to sort it with the tires is during the curing process : it is difficult to have the inside of the tire exposed properly... One of my friend suggested a UV led ribbon. It can be cut to fit a certain length, and is powered by USB...


I just need to build a structure to position it easily in the tire center, bring the usb cable in and this without disturbing the nomal curing process. I decided to bring the usb cable from the top and I still need to find a way to power / unpower it easily...

I'm sure you'll find a solution like always.

Translucient resin so, you can build red green yellow or blue tires. 😜

While the printer works, I built a tool

a 2020 extrusion, few angles, few t-nuts and screws...


That should be practical to empty the VAT with a filter on top of the bottle...
