Gizmo Dorks 1.75mm Hips Filament 1kg / 2.2lb for 3D Printers, Brown

I think as far as HIPS goes the mechanical properties are pretty standard: very stiff, very lightweight, somewhat liable to warping on the build plate even at 110C but not as bad as ABS. Actually the weight threw me off, you probably get much more filament than you're expecting from the 1kg net weight if you're used to PLA or PETG (not sure about ABS.)The orange isn't quite all the way to "neon" orange but it does glow orange under blacklight. It's almost as if it's 20% white and 80% orange dye. 0.8mm and thinner sections are ever-so-slightly translucent.I originally bought this with the hope that I could use it for support material for PETG, since I couldn't find much information on supporting PETG. Turns out it sucks for that, you really want PVA instead. The other issue I had is it absolutely does warp at the base on any large long prints on my dual-extrusion printer (Hictop D3) that has a print bed that's firmware limited to 100C (it shuts off if you hit it), and can only reach that if you insulate the bottom of the bed to begin with. My heavily-modified Ender 3 (with SKR 1.3 controller board) with a garolite bed easily reaches 110C and I may try 120-130C soon to see if I can get rid of that last bit of warping.I've been using the HIPS as its own material since then and I almost like it better than PETG for anything structural, which was my main purpose for the PETG to begin with. No stringing at all, bridges fairly well, and it can be smoothed with limonene the same way you'd smooth ABS with acetone, but without having to deal with the toxicity of acetone. I think HIPS is also supposed to be more chemically resistant and more UV-resistant than ABS but not as much as ASA, though it's tremendously cheaper than ASA.The only thing I think I could ask for is some fluorescent translucent filaments from Gizmodorks, similar to 3D Solutech's "See Through" PETG line. I think I'll be buying the neon pink and green next.

Given how this product is advertised, I picked up a roll to see if it can be a decent general purpose filament. The first problem I ran into is that it's bed adhesion is very poor. I use printbite for my beds and it's never failed to stick to a filament. If anything it sticks too well to some filaments, but it's never failed to stick to something. After cranking the bed temp up above ABS temps, I got some bed adhesion--enough to allow a small print. It took three attempts to print a 4.5mm tall print. I tested the failed prints for strength. They failed horribly. This plastic is very weak. It's like ABS meets candle wax. It's soft to the touch--you can dent it with a thumb nail. I easily tore the model apart with my hands. I've never used a plastic this weak before and that includes polymorph.This plastic is simply not suitable for general purpose use. It's too weak and the bed adhesion is too low. I'm afraid this filament is really only suitable as a dissolvable support material. In which case, it doesn't make sense to have multiple colors of it.Please don't choose this product if you are looking for a general purpose filament for 3d printing.

Bought this for my PowerSpec Pro 2.0 (Same thing as Flash Forge Creator Pro, just MicroCenter branded) dual extruder printer. Bought this to use as a Support Material. From reviews on YouTube and other sites I did not have much hope for it as the notion was that it does not stick to the base material thus would require to be anchored directly to the table.In my case, I printed couple of parts and was happy to find that it actually does stick to the base material pretty well ( I printed with PLA as structural and HIPS as support). On first part with 90Deg overhangs I had both materials anchored to the table and it worked very well. On the second part (a ball bearing) I had features where HIPS was attached only to the PLA material and the balls were suspended completely by HIPS and it worked very well also. Nothing came apart during the print and was in tact. I ran PLA at 205C and HIPS at 240C. Relatively easy to remove, had to use some solvent in some corners. On flat areas can be pried off with small knife.Overall, I would say it's a good balance of adhesion (on the PLA for sure) to provide solid support and release for removal. The remnants are easily removed with Solvent.

So, I've had my roll for an entire year now and it's still not gone! This stuff lasts forever if it's only for support material and your prints aren't huge. I've got a dual extruder printer and this is great for ABS prints.You can print the ABS layer right on top of the HIPS layer and it will separate fairly easily no issue. I find that making custom supports with a grid pattern and a flat sheet on top of HIPS leaves a pretty nice finish if a flat abs surface is needed that is raised off the bed.Now adhering to the print bed is probably the toughest thing with this material. You need to crank the temp up a bit to at least 85ºC on a heated bed for it to have a better chance to stick. I use the blue print mats, and you also need the print bed to be pretty close to the nozzle to ensure it sticks. I find that the ABS will stick just fine with a larger bed gap, but sometimes the HIPS will peal after a few layers.It might help to maybe print a Raft for the HIPS or if you make a custom grid like me, make the first layer much thicker so the surface area holds it better. Once you dial it in and the support stick, its awesome.Pictures shows what the white HIPS looks like as a support layer, and the surface finish between the build plate and the HIPS Support.
