What did you 3D print today?

Maybe enable z hop for supports and print the supports at a slightly slower speed -10%+- so if it does collide with the nozzle tip it doesn't snap the support trees.

 

Question for you experts.

I've been throwing around some designs for a 3D printable intake plenum and manifold. Think a 3-4 piece design that bolts into the factory intake manifold of a 5VZ-FE.

Temperature-wise, I'm not sure if I 100% need to make the entire thing out of PA6-GF, or if I can get away with PET-CF at half the price. Any of my designs will seemingly take around 2kg of filament, so PET-CF would be the price point closer to reality. Do I risk it? Or do I just make sure the areas contacting metal are PA6 and let anything with radiant heat be PET?

Keep in mind the inside will be constantly flowing air that's gone through an intercooler, so the inside will be under 150*F, but the outside will likely see above radiator temps in some locations (230*F/110*C). PET-CF is supposedly good above 140C and PA6-GF above 180C. Mainly I'm worried about hot spots I can't predict.



In unrelated news, I have an Ender 3 S1 for sale

 

My spool of ABS-GF was $26 (1kg). It's relatively cheap and will have better warp resistance than PETG. It's only downside is that it's also going to be the least flexible of the filaments.

 

PETG and even ABS/ASA heat deflection temps are too weak to be considered here. This is PET

 

My mistake. I did not realize that there was a glycol-free version of polyethylene thppthrth out there.

 

Turned out well! Thank you again! Would you be cool if i shared this on Printables and tagged you? Let me know if you have an account there or not.

 

Feel free to share, no need to tag me, though, not on printables and also don't tag me because I'm ashamed of the jagged edges where I cut away under the clip

 

thanks again!

 

Yeah, happy to help. Did it during a boring webinar. If you step back through on the model with the undo button you can kind of see how I did it in Tinkercad. Just some simple square shapes and then manipulating them to be holes or solids depending on what I was trying to delete. Trim out everything around the clip, trim out a hole equal to the clip on the second piece, merge them together. Tinkercad is phenomenal for simple shape things like that.

 

will take a look into it!

 

We started having strength issues (layer adhesion) with our Bambu X1C with Bambu PETG-CF, put in a different extruder and hot tip, recalibrating and as a final trial used Tinmorry filament. It was the filament. So now we have like 15 rolls of bad PETG-CF.

 

define bad. I've never played with PETG or PETG-CF, any chance running it through a dryer would make it better? I think I recall PETG is super sensitive to humidity - even to the point of needing to be dried fresh out of the bag.

Did some Googling, it looks like it isn't as bad as some other filaments that Bamboo says 'Require' drying from the bag, but with 14 rolls, it may be worth a try...

 

I have to dry my PETG to run it in my Bambu Labs P1S. I try to get it below 20%.

 

We run all of our material thru a Creality dryer at 60c and store it in a bin at 17% humidity, so that's not the problem. We tried 4 different Bambu rolls and 1 Tinmorrey that was finally successful.

 

Interesting. Maybe try contacting Bamboo. I pretty much only use Polymaker and Overture in my Voron.

 

Speaking of drying, I found out my oven has a proofing setting that keeps the light on for the heat source and turns on the convection fan, so it works like a blast oven. And ofc that means I can throw like all my filament rolls in at once lol, score!

 

Picked up another QIDI Q1 Pro, the first one died a terrible death, due to circumstances. Later i picked up a replacement an after some careful tunning got it to print decent.

one of the first things I did was design a switch blank panel for the front of a Rigid toolbox, that will house the new portable battery system.







After several iterations, the above was the final design...

I also decided to pick up a new 10" android tablet for offroad navigation use. which also meant buying a new mount. I am big fan of the Ram X-grip. I went with the RAM-B-101-C-U9U an quickly discovered that the end arms that come with it block the Charge port.



I ended up staying up late and modeled up a replacement.



the long tabs where the rubber bumper is, is a bit fragile but I think that will be resolved with a different print orientation.



But it does the solve the issue it was meant to...

the most recent prints are some 3d Scanner marker blocks. I just ordered the revopoint metroX 3d Scanner, and I was not about to pay over $200 for a hand full of scanner blocks. A quick search on printables and found I was not the only one.

 

Jealous, I've been wanting a scanner for a while now. Let us know how you're liking it when you get it.
