3D Printing What Are You Printing Today?

[mpitfield]

Pretty cool design. You should help or participate with the 3D design challenge.

I just uploaded my design to Thingiverse https://www.thingiverse.com/thing:3968769

Almost halfway into my Malemute fincan.

Meanwhile, over in this thread...

... it's slowly getting there.

 

[dr wogz]

8 hours worth of work prototypes..

Sorry, can't share pics..

 

[Charles_McG]

My fincan print failed at 36/56 hours. The restart lost adhesion at the tips and is warping up.

Well, if I can’t fill and file, I can always reprint.

I had a terrible time getting the restart to stick. (I resliced at the appropriate height- I didn’t try to restart the old job.) It turns out that I was underextruding by a lot. The end of the Bowden tube was partly clogged. I changed out the nozzle and cut half and inch off the Bowden. I think the remaining lifting problem is mostly Z offset tuning.

Hair spray. Trust me it works.

Hair spray. Trust me it works.

I use the Creality magnetic bed. I’ve had mixed luck with Auqanet on it. Usually I find adhesion to be more about z-offset for the first layer (by material) and good extruder flow.

I’m beginning to think about doing a single layer sacrificial piece after cleaning with iso-propyl.

Then a raft might work.

I'm still a noob compared to most of the contributors to this thread, but I'm a fan of both the Creality magnetic bed and of rafts.

 

[Charles_McG]

I think I’ll reprint. The gap I could fill. Getting that leading edge right again??? Not so sure.

And I’ll update the ID while I’m at it - it’s a bit tight.

I go through long stretches where the bed works great. And then something happens. I clean it off. The first couple of prints have adhesion issues. Then it settles in and works well.

I’m trying the Overture clear PETG, since it seems to be the Amazon brand o’the month.

Charles,

Our maker: Fusion3, recommends a regular school glue stick.. Elmer's school glue, purple.. 3 layers of glue stick for PETG (2 at 90° to each other, the 3rd at 45°)

24/62 hours:

 

[DumasBro2]

Printed this a while back, PETG. Print quit after about 4 days so I finished the rest and will have to trim and mate.
I print on glass with White Rain extra hold hair spray and that works well, I find glue stick makes a mess of the bed. Printing the escape tower is a real challenge. Some time I want to try to use PVA for support. Seems like an ideal solution for the tower.

 

[Charles_McG]

What scale?

 

[Charles_McG]

48/62 hours

 

[DumasBro2]

What scale?

1:30

 

[Charles_McG]

74 hours, 50 minute.
Cura wasn’t exactly precise in its time estimate.

 

[cwbullet]

Little bit a few days off. I have to do some maintenance. Good news it is still covered and prusa is shipping me the parts,

[TurbulentSphere]

Printed a new motor mount so I can fly my (normally electric) RC airplane under rocket power.

 

[Charles_McG]

Printed a 3” 11 degree total angle cone as an outer contour. It failed about 2” from the tip, which I reprinted normally, with a shoulder.

It’s PLA, but my plan is to foam fill it, then glue in the shoulder.

T344 to BT80 coupler Terrier Interstage.



This is Overture clear PETG, and it’s performed really well. I suspect Overture is the same as Amazonbasics was.

As Hatchbox has gotten scarce, I’ll be using Overture for a while. The color options are limited, but I can live with it.

I finally used up my white eSun PETG. It’s been my least favorite so far.

 

[cwbullet]

Overture is the same manufacturer as Amazon Basics and one other manufacturer.

I printed a new nosecone for my ACME Spitfire. Huge thanks to Alan R for designing it and posting it to Thingiverse: https://www.thingiverse.com/thing:3987864


And I printed more Keck clips for my lab on my Anycubic Photon, this time with Sirya Tenacious resin. These clips are a great test for new resins. Where my other prints have been a little too brittle, this resin is quite rubbery. I think it's time to brandish my chemist credentials and start mixing stuff in my basement this weekend.

Chemists stick together like glue, you know. Mostly because of spilling it on our lab coats.

Huge thanks to Alan R

Wow. Cool! Thanks for the mention. I hope it works for you.

Mine is mostly finished. I'm still contemplating whether or not to paint the fins silver just for a little contrast

Bulkheads... lots of bulkheads. 100% infill really eats filament!
