It has been a while.... And a lot of learning. All of my printer issues were fixed mostly with 2 steps. #1, a new nozzle. #2 Reducing print speed.
We are re making 2 suites, Emily and myself. That means a total of 4 legs. To get 4 good legs, I think I have printed the equivalent of probably 8 .35 legs. The good news, I have 2 good right legs and 2 good left legs. Sizing mistakes, (Armosmith is ... complicated), bad print settings, weather (In Jan & Feb, the room with the printer gets really cold over night, then the heat comes on and it warms up quick. I think that caused some of the overnight failures. Right or wrong, I'm blaming the weather.) Then, While sanding, a couple of calf parts fell off the table and cracked when they hit the ground. Apparently 2 wall layers is not enough. Most of the stuff in the bucket is 4 or 5 wall layers. I used TPU for Emily's inner thigh parts.
Anyone ever epoxy TPU with PETG? If it works well, I may reprint my thighs the same way. We may try simple velcro to hold the parts in place. She likes it. We will figure out a way to make it work. FWIW, I'm planning on doing the Butt Plates in TPU. That could be a 40 hour print per part. 40 hours, now that's a commitment.
We finally got some good weather and a clear calendar. The legs got their first coat of primer on. That 2 tone knee in there is a Paint test part. I actually have a lot of "Test" parts. Yea, that's it. They are not failures, they are not wasted spools of filament, They are Test Parts! There, I feel better now... LOL.
Bottom line, We are making progress. That black thing is a forearm. After legs, Arms seem easy. I expect to have 4 good arms by the weekend, so lots more sanding priming, and maybe even some actual paint.
Quick question. How many coats of Primer filler, primer coat, paint, & clear coat do you typically average?
I know, it all depends. Emily was thinking 1 coat of filler primer, and 1 coat of paint. Based on my testing, I expect 2 coats of filler with some areas needing a third. one coat black primer. And 1, likely 2, coats of Paint. Does a layer of clear coat help? Hurt? make a difference?
And...um, does the weathering come before or after the clear coat? ! I know.... More uses for those test parts!!!
Thanks for playing!
