My first 3d additive design/manufacturing job.

My first 3d additive design/manufacturing job. Small table gifts for a social group yearly lunch event. Also printing a red heart shaped stand and some flat topographic style print wing images for an angels and hearts theme. It’s just a knickknack box for pills or mints or coins, maybe jewelry I hope if someone likes it enough. Not my best design work as I am new to this form of manufacturing. It was only a few days to design and then figure out the printing, initial concepts were too complex and took way too long to print and get it all done design to delivered in 18 days. Had to redesign a simple box without a complex hinge that I knew could meet the deadline.

A more experienced person would get this done so much quicker, that for sure. I made some wrong turns but learned lots about designing for additive manufacturing, reliable deadline based manufacturing not ‘well I will just restart it’ making of stuff for my own use.

Prints are .15mm layers, 50mm/s base speed 25mm/s perimeters. 1 hour for each top and bottom, with the prototypes and other stuff MiltyKoss has been running for days on end now with only the time it takes to remove and start another print as a break. The Delrin bushings, epic. No adjusting no fiddling no wear showing at all, wish I could say the same for myself. I was up all night Wednesday to ensure the deadline was going to be met, set alarm to go off at the end of each print and got 45 minutes of sleep at a time. I have 6 days but 4 are for shipping so it’s going to be close but should get done.

This is T-Glase white, needed the ‘food safe’ FDA approval otherwise I would have done it in a white PETG I am more familiar with. I like the T-Glase, but tuning white filament always is harder for me. not sure why but it just seems to be sensitive to heat and over or under extrude easily, seems to string more as well. Thats for ABS PLA PETG and Nylon from 5 manufacturers I have now tried. I think it’s the pigment, might just be me though. I do not have my ideal bowden setup yet, still too long but have retraction down to 3-4mm so much better than top mounted extruder I had before.

10 units to deliver plus some spares if possible, about 1/2 through as there are the stands and wings to print as well. Expect finished and shipped Monday, which will be a huge relief to get done so I can print something, anything, other than another !#@!#!!! heart shape :stuck_out_tongue:

Quite a heaven of an experience for you: ) Print quality is good.

You used S3D slicer?
(I’ve never used it before).

Your perimeter 25mm/s. What about the inner shell settings?

I am keen to know inner vs outer shells(perimeter) settings. Tks

Very nice!

I love these! :slight_smile: This 3d printing just amazes me!

Cool project.

We’re in the same boat with white filament. The only success I have had is with white PLA from printrbot. Everything else was just awful to deal with.

@Brian_Wilson what i suspect is going on is that the white pigment is reflecting IR wavelengths just like a white car stays cooler on a sunny day. I heard in a YouTube video a while ago that titanium dioxide is the pigment for white, that is also a great sunscreen, and thus is great for blocking IR and UV and other wavelengths of radiant energy.

The more vibrant and energy absorbing the filament color the better it seems to work at absorbing radiant heating evenly/consistently. Not sure, just a new theory after struggling with white. Some ‘white’ PLA from Solutech actually printed pretty consistently, but I would not call it white by professional design standards, next to an actual white object it’s obviously not its faint faded yellow, not unpleasant but not white. If a client is going to mount it on something white for in person viewing it’s not great, photos could easily be fixed in lightroom to make it very white though so it’s passable for some projects I think.

Ssssssoooooooo ccccuuuutttteeee!
