Can see though how you'd like to have it on here.

also was planning on doing a nylon 6/6 write up, but my last attempt had mixed results, and haven't got it to print very well.
on the other hand I took a ton of pics, tried some funny stuff and also shows a pc extruding setup.
i'll put the pics on imgur when i find the camera.

@josh thanks for the mixing tip, and the agitator model! i'll have to try that.

turns out the sd card with all the pc and pc abs stuff got damaged, so lost those pics, using pc abs on quadcopter frames now and its amazing. anyway here's some quick upload of a bunch of the nylon pics and stuff, still have a few lbs of it so will have to try again, but ya w/e i'll make a thread here about materials and stuff sometime,  http://imgur.com/a/58lZB

received 10lbs of hips today, got it started and been taking pics, i'll be trying to get to that write up after a few prints with it.

Since there isn't much on the forum about HIPS, for future reference to anyone who wishes to use HIPS:

I found best results using about a 75:25 mixture of d-Limonene & Isopropyl alcohol (respectively). The alcohol doesn't mix with the d-Limonene, so an agitator is needed. I used a glass pint jar filled to 40mm from the top and printed a bracket for the motor to attach to the lid and an agitator for the motor. Files are attached.

-Smaller parts took 2-4 hours for the HIPS to dissolve.
-It is best if you remove some support by hand before starting; this cuts down on the dissolve time of course.
-As elmoret stated, HIPS definitely doesn't play well with ABS. It made the parts a little bit soft but they seemed to harden back up after drying. No extensive testing has been done on this.
-The color in ABS seems to dissolve into the d-Limonene. I did not see this problem with PC, so perhaps this is just part of the Styrene in ABS dissolving.
-I also found out that my filament spools are made from Polystyrene (as clearly marked on the spool, dummy!) - so using one as a tool rest for tools used to reach in the jar was really not a good idea.

In this picture, these parts were printed upside down (like the part on the left in the background). The picture doesn't do it justice, but the supported surface is really smooth and flat. Parts here were printed with filastruder PC and store-bought HIPS.

As seen here, the d-Limonene and alcohol separate. You can also see where the orange from my test ABS has dissolved into the d-Limonene. You can see the motor/agitator assembly clearly here.

Agitator mixes the d-Limonene/Alcohol very well and also helps speed up the process by tumbling the parts.

cor5151 - Take it if you have the time to do a writup! If not, I will be making one in a week or two.

i'm working on pcb stuff now and have 2 large cnc/printer/laser builds underway but havent made to much progress over the summer, mainly cuz lack of funds and motivation.

if ya ever need some help with a build or something let me know, i'm waiting on a kickstarter for my 5th printer that has a heated chamber and core xy drive.

@josh  where u at in sc? im in the upstate and been using hips for over a year. extrudes great and dissolves good, but most of the time can be removed without solvent.

can print up to 15x15" idk how big your print is, and what temps its gonna have to take, looks like a small engine pull cord cover.
also working with nylon6 and pc now

Upstate as well. You're the second person I've met on here that's within an hour's drive!

I've been using HIPS for about the past week now, and it seems to work pretty good. It is easier to remove it than ABS since HIPS/ABS doesn't seem to bond anything like ABS/ABS.

With smaller parts, supports usually dissolve within a few hours using an agitator.

Ok, guess my printer just sucks then... I would go with PVA as it is water soluble to my knowledge while hips requires Lemonol which here in the United States is not common.

Like anything else I guess you just need to look. IMHO it is common just not by that name and not in concentrated form.
It is however a bit pricey.

d-Limonene is a very effective, naturally
occurring, biodegradable solvent and
degreaser, extracted from the peel of
oranges. It is 100% natural, environmentally
friendly, and non-toxic. Due to its attractive
citrus aroma, versatility, and Generally
Recognized As Safe (GRAS) by the FDA,
d-Limonene can be used safely and
effectively in a wide range of products.

According to the product guide sheet from florida Chemical  if you intend to mix with water you either need to add a  sufficant or buy a D-Limonene product with sufficant that is designed to be diluted with water.

And I have seen HIPS on the shelf of Micro center.

I tried Simplify3D a while back but it was when I was in the middle of figuring out which material I wanted, and I found that repetier + slic3r made it much easier to change between materials. I'll give it a try again.

You must check frequently to make sure the ABS is not getting attacked, but usually 10-12 hrs in the tank works out well.

Acetone damages/dissolves polycarbonate, if that's what you were thinking of pairing with ABS.

Have you tried Simplify3D's supports? I haven't, but I've heard good things.

Sorry this post is kindof off-topic now.

Do be advised that D-Limonene dissolves Styrene, which is a component of ABS. As a result it doesn't play nice with ABS.
