Squeaky wheel? It was in the second post of the thread, the very first response to the original question. All the squeaking came after the question had been answered.
lol.
Guess it only took one squeak then,
<snip>I think the language barrier plays a big part here, too..<snip> ...example would be the "slight warping issue" of z-glass. I'm pretty sure it is supposed to mean "with minimal warping issues". <snip>
Absolutely. A small attempt at trying to understand what is being said by non-native writers would go a long way, @Josh. You remind me of an American tourist who thinks he can make foreigners understand him better if he shouts at them. I look forward to reading some documentation or marketing materials written by you in Polish.

I'd hire a polish copy-writer, but that's just me.
If I wanted a foreigner to understand me better I'd draw them a picture... pictures are the universal language. That and C++.

I have to admit that I did not click on the link because I (wrongly) assumed it just goes to the msds sheets.
The matrix is really good and it should have a prominent link on each material store page and even at the top of the first material overview store page. I would call the link “compare the materials”
Nice thread. Don't mean to hijack, just didn't want to start new one since my question is related. Lol
I am curious…(that link to article is bad)…if zhips is stronger than zabs?
I started a print with zhips and it pulled off platform so I stopped print but was printing a shelf clip that will be attached to wall for floating shelf. I did a test print with zabs and that clip was strong now granted the print was only 20% done with zhips but the material broke real easy.
I am ordering zultrat but not for a week or so but for time being I wanted to get shelf installed and after seeing the zhips break so easy I’m thinking of using regular abs.
The shelf will be about 4 lbs and what it holds should only be 10 lbs max so any insight??
Thanks
Update__-- I went ahead and did a full print on the clip and I am not unimpressed. lol Seems very strong and stable, more so than the reg abs. Should do just fine for my shelf and reading the information about it, the tensile strength is high. Oh Joy! lol
Cheers
Would be nice to see a materials sheet for the new materials similar to the ones available for ZABS and ULTRAT.
The chart that people were referring to has been moved here: http://support.zortrax.com/hc/en-us/articles/202143321-Z-Filament-Series
It's a great start - thanks Zortrax team!
In addition to the information on that chart, there is some additional "pratical" information that would be a great help to see on this chart:
- What is it's Melting Temperature
- What is it's Glass transition temperature?
- What solvent can you use with it?
- Can it be treated with a vapor bath?
- What is the best type of glue to use?
- Can parts be solvent welded?
- How well does the material take post-printing machining (sanding, drilling, etc)?
I'm sure I am missing some other key questions, but I bet the community will chime in. Perhaps we can even start flushing out some of this information ourselves.
Cheers,

Z-GLASS hasn’t warped during my (not comprehensive) tests, but it’s brittle, breaks into sharp edges, and will cut you during cleanup if you’re not careful. The raft is difficult to remove by hand on parts with wide, flat bottoms; I’ve found a sharp, heavy chisel (no hammer necessary) to be the best tool for removing it. Z-GLASS is also particularly gooey/sticky/stringy when melted and is prone to clogging. I spent a good chunk of time yesterday clearing a wad of Z-GLASS that solidified on the extruder pulley during unloading. Not fun.
Hi guys,
did you noticed that Zortrax is using weird data sheets for their materials?
Moreover, they are not testing all material properties in the same way.
A good example for this is the hardness: They are saying that Z-ABS has a hardness of 20,5HB (Hardness Brinell) although they point out to use a test method, which is using hardness Rockwell (->ASTM D785). The hardness for Z-HIPS and Z-Ultrat is mentioned in Rockwell. So, you are not able to compare these materials in the property of hardness. After I have noticed stuff like that, I contacted them and they sent me new material data sheets. There they tell us that Z-ABS and Z-HIPS have the SAME hardness of 109R (Rockwell). Moreover, Z-Ultrat has a hardness of 110R (Rockwell). They are saying that Z-Ultrat is 1Rockwell harder as the others. As far as I know from steel hardness measurements, the gadgets which are used for these tests often have a tolerance of about 3Rockwell. So, as you can see, 1Rockwell is actually nothing. But then, have a look at the chart on their homepage, where they discribe and compare their materials with words like high, medium or low. There, they tell us that Z-ABS has a medium and Z-HIPS has a low hardness. But as you can see in their data sheets, they have the SAME hardness. In addition, they are pointing out that Z-Ultrat has a high hardness, although it is just 1Rockwell higher.
When I asked them: when do you release Z-Nylond and Z-PCABS, they told me that they still have problems with shrinking and that's why they are still testing the materials. Maybe, the reason why they haven't released them is that they got wrong/bad information about the company which tests and maybe produces the materials.
I really want to print some more functional and more useful parts soon. So, it is important for me to print with Nylon and PCABS. Of course, it is also very important for me to get correct material information. That's why I'm writing this post! Please, don't hesitate to rectify me if I'm wrong!
I will attach the new data sheets they sent me.

Z-materials specification purpose is mainly the general information. The tests has been conducted on elements of the injection mold. In our opinion there is no point in testing the printing samples because every change in the software also changes the properties of the printed sample. It means that we would need to do the tests every time when we would launch new update of the Z-suite.
We're grateful for your opinion and we assure you that we will make every effort to make our information as solid as possible.
Best regards,
Chris
