You guys know this: PLA works great as support interface material…
…but PLA+ does NOT!!!
I just printed something with black PETG that required supports. I decided I wanted them to release easily so PLA has always worked beautifully for me. My AMS had a roll of red PLA+ in it so I thought that would work just fine.
WRONG!!! It fused the support to the object as if it was part of the piece. I had to cut and chisel the supports off. The PLA+ is still attached.
Zip tie tightener
I held out as long as I could, but I finally had a NEED for fusion. Designing a handle for stop signs for school crossing guards. The standard ones come with a cheap wood handle with wood screws. This will be 3d printed by a friend while I contemplate a purchase.
Watch out Jon! You are flying too close to the Sun my friend.
It is so fun. Recently I made a heavy duty handle for outside gate or wooden boxes. I kept debating how to attach. The next thing I knew, I designed the handle that could be attached multiple ways.
So far I have used all three methods in different applications.
That’s pretty slick. I’m already going back to modify it to add threads In the bottom, a lanyard hole, and I have to make it so the cutaways for the nuts have a base to clamp. I want to change the handle profile too. I think I can modify the base sketch to do that, about to find out.
As far as threads go, I am not real proficient with the heat inserts. Sometimes they get a bit skewed even though I am using a press that is designed for the task:
My favorite and fool-proof is using a real nut (drop-in or create a well for it). That way you don’t have concerns of the clearance with the threads and the threads will NOT strip out on you like the plastic threads could.
I don’t believe the press I have would have helped for a few of those that you did.
Where I had issues was drilling holes at the exact location of the inserts and having the bolt go thru 3/4” of wood. If the insert was exactly perpendicular, it worked fine. If it was off even a smidge, I had to go gorilla on the hole to give some leeway.
Not a Glock or a zip-tie tightener. BUT, not quite there yet either. Still, I love this tech. I hope it doesn’t get banned…
Doing some lost pla casting? Definitely something I want to try in the future.
It’s actually just basic sand casting. VEVOR electric furnace, and some petrobond sand rammed into a $20 Amazon cast iron flask around my 3D printed pattern. Relatively low buck setup. Decent results for a first ever attempt. I’m refining the pattern and trying again today. Creating a pattern that will pull cleanly out of the sand seems to be the most challenging part of the process.
PS-I too hope to try the lost PLA or investment casting process at some point. There’s definitely more to that.
This is pretty funny
Put this in my cart! Thanks for sharing!
A while back is when I was discussing hexagonal shafts and blades for a plastic mulcher.
Someone, I lost track so to say now, wanted to get a set up going for his wife:
.f3d file listed can be used as is or as a smaller or larger footprint (obviously).Blade_One.f3d (73.5 KB)
One could easily cut out the Blade_One.f3d file on thinner or thicker materials for hexagonal shafts. Just for giggles here…this is what I printed in ASA for testing purposes.
Wait…now my telephone (circa ‘95) is not uploading data to the computer. Blah. Oh wait…
Nope, still nothing.
and…
I give up on the 3D Printed part file (.jpg) being sent to the ole desktop. Blah.
About 5 years ago I had a customer approached me to build one of these shredders at a stainless steel.
Never ended up doing it because they didn’t have the budget but as soon as I saw that picture of yours I knew it was from “precious plastic”
The v2.1 shredder is from Precious Plastic. They have made strides around the world with the inventive ideas they have completed.
That .f3d file is from another type of shredder but I changed it to suit the needs of this forum…
Let me see if the upload ever happened on my Phone to desktop:
Okay, I have had to make a screenshot of it on its upload process instead…here.
This was the first idea(s) or an idea from here: LibreShred One | 3D Printed Single Shaft Shredder by AZ3D | Download free STL model | Printables.com
I changed it. It is like paraphrasing but for LibreShred One. I changed the file to suit my needs. I wonder if he/she will be upset. Anyway, I can do it justice with AMA or MLA formatting but who knows?
I printed the parts for a 6 meter HAM radio antenna. I had to redesign it some, I little ends on the end of the spreaders are not working out. I printed a different design last night. But woke up to 8” of snow this morning so I haven’t looked at it yet today. Here are the parts I printed over the last couple days and the basic layout of the antenna. I don’t like the feet point either, so I’m going to redesign that also.
Has anyone seen 3D print for this math monkey?
Edit. NM I searched math monkey and found it 10 seconds after I posted this.
The new version of the dummy 13 has come out. Carbon 13. I just started the print.
