About to buy an R1

So I'm just doing some thinking about different things I can do with my prints. I'm printing a 8"x4"x5.5" fixture to check the angles of a part we brake form. If i left off the top layer what woukd i use to pour into the print to make it completely solid? I would need this tool to last and maybe with some weight or something to bond it all together would help. Then I could speed up prints by using way less infill. I'm sure different epoxies or resins will bond differently to different filaments.
This could open up a whole new world. Hydroforming is a large part of our business and if I could print tools to handle 5,000psi to form parts that would be huge.

 

Im tempted to cancel this 24hr print 3 hours in and start over with way less infill..

 

High density impact foam would probably work however it takes a very long time to cure.

Depending on what I'm printing I normally keep my infill down to about 10%. Now if it's something like a sword I normally print about 50 percent infill

What about just fiberglass resin? I used to work with fiberglass a lot, and as much as I hate everything about working with it I feel like something I could just pour would work great.

Interesting, this print is looking pretty good so I guess I'll just keep it going at 20% fill but I have an opposite to print once it's done and I'll lower the infill down as low as I can and keep researching for something to fill it with. Since I got this printer to finally work maybe I'll just request to keep this second one they're sending me. haha.

 

Fiber glass will be heavier and not as strong as impact foam or maybe you could use balistic gel. It has the same workability as fiberglass but cure time is less. And you can actually make it out of house hold products

All of our tools are built with aluminum plate and aluminum risers or machined out of a solid piece of aluminum so the problem I'll face is convincing people that the printed parts are strong and will last. We have tools that we still use that are 40+ years old.

If anything I would want the parts to weigh as much as possible I think to give it the impression of being sturdy.

 

I think I would want something that will bond the outer layers if possible. Why do you say fiberglass wouldn't be as strong? It seems like that would do a better job of actually bonding but I don't know the science behind it.

 

Printing beautifully and fails at 14.5 hours... Now that's frustrating

 

I'm guessing if i wasn't still using mattercontrol i would be able to figure out my Z height and go back and start the program from there. Guess i should have just got SImplify3d up and running.

 

For simplify3d on my printer with the hex I'm using .85 and the chimera I use .79

well i got some polycarbonate in and finally got it to stick with blue painters tape, elmers glue stick, and 280 degree extruder temp. My issue is now that it will print for about 3 minutes and then all of a sudden the temp will slowly drop to 250-255. Wtf! It prints good at 270-280. Is my machine screwing up or will it not stay that high?

 

watch it, what may be happening is youre printing too fast at that temp so it's hitting the sanity limiter at 300. You can change what your limiter is set at in the firmware. mine is set at 375C on my chimera, and 310 on the hex

 

Hmm ok. I turned it to 267 and its still dropping to 255 but still printing. How high can I go with my bed temp with poly? I'm at 85 and still getting corners lifting. Seems like this poly is feeding better and will be better material than the petg for what I need if I can figure it out.

 

if you print too fast your temp will go down. max bed temp is 100 but if it goes over it will sanity shut down

 

Spoke too soon, got kinked and failed. Corners were lifting anyways. Off to try something else. Thanks again. It looks like it's bonding pretty well at 255 so I'll try leaving it there.

 

you could always try buildtak or zebraplate

 

Amazon has buildtak but dang it's pretty pricy. Might overnight some anyways.

 

It lasts for quite some time from what I hear. I've never used it but some of the guys on the forum love it

Cool, worth a shot. Thanks.

 

See any reason why the poly would have failed to feed? It's a lot more rigid than the petg so I was pretty confident it wouldn't bunch up.
