3D printable coil housings

[BKY1337]

Hello,

Has anybody 3D files from coil housings? I need a 10 inch one for my TGSL.
I make one at the moment and i need to print it on a 220x220mm heatbed.
I planned to cut the whole coil in 4 Pieces and print it with PLA because ABS warps.
Has anybody done this before?

I'm thinking there was a post on 3D Printing of housing just this last month or so.. I can't seem to find it .

I made one and removed the ears to print it upside down.
It looks like the sides are still too wide. Don Bower said his space between the walls is 20mm.
And im not sure how i should glue the four splitted parts together.

Not keen on the four peace thing. Maybe if you just printed it slower it would not warp.???

The problem is that i can only print a 220mm x 220mm big thing.
And the coil is 270mm.

Guess ya need a 3D Plotter ! LOL

I made a ten inch coil out of abs you be able to print it off your 220x220 easily however you should really be using ABS just because you can weld it all together better then you could with PLA, also at one point you will want to fill it with some kind of resin and pla in not chemical and heat resistant like abs is. PM me your email and ill send you the Slt's

Hello, nice coil housing. Are you sure about the chemical resistance of PLA? I have a lot PLA left and i ran out of ABS.
How do you weld ABS together?

I thought about glueing it toghether with a layer of fiberglass/epoxy at the inside.

Unfortunately your coil housing is for PI, i need one for TGSL EDU Double D - Don Bower style.

It will be cheaper to just buy one off ebay - http://www.ebay.com/sch/i.html?_from...tor+DD&_sop=15

I made huge 60cm coil with 3D printed ABS, it was quite hard to glue the pieces together, and it warped quite alot from the epoxy resin while laminating.

I dont like this housings and i have to pay 18 euro for the HIPS one.
It costs me about 2-3 Euro for one housing with PLA or ABS.

There are cheap china 3D Printers with 400x400mm heatbed. They would be perfect for whole coils.

In this case don't make the walls too thin, probably 1+mm is going to be fine, and brush off a little bit of resin first, let it dry then repeat this step again to make it stiff and avoid warping.

Thanks, my walls are 2mm and 3mm at the upper surface. I will print it upside down and then i want to clamp the connector thing
on it from above.

Maybe my walls are too thick.
The only problem is that im not sure about bed adhesion , i have no problems with ABS, i use ABS Slurry for that, but im not sure about pla at such dimensions.
Had very bad results with hairspray, better results with glue stick but still not perfect.

Maybe my walls are too thick.

There are no 10'' housings at ebay by the way.

Its rather easy to get ABS parts to weld to each other, you can use acetone with works really well, personally I "weld on primer" made by IPS just because I have cases of this stuff, it also works great. yes im sure about chemical resistance of pla, also it warps easily in direct sunlight for long periods exposer but there is a trick to that, If you use a fiberglass resin with a ultraviolet as the curing agent, something like Ding all suncure , you can apply quickly and bring it out in the sun it will cure fast which will minimize the pla from melting. in a little while ill be making a DD housing for the mmp but its not made yet, So that doesn't help you at the moment.

Those prices are cheap indeed if I wouldn't have a 3d printer id defiantly get on of those , My 10 inch coil cost $4.25 in plastic, but that's not counting the time it took to cad it out mind you, like I said before I use ding all suncure which
cures in a matter of minutes when exposed to ultraviolet light.

Wall thickness should always be calculated with intended nozzle that's going to be used, and with number of shells it will get. normally most printers has a nozzle of 0.4 so you make the walls 0.8 or 1.2mm and so on.
