wiper skynet 3d printing in 2014 was
Thanks for your comment Latarsha Stefan, have a nice day.

there are numerous 3d printing materials on the market PLA ptg and abs or it's very similar counterpart a sa are probably still the most commonly used ones I took these three materials from the Peru sham and lineup and compared them side by sides let's find out how they print look and perform in mechanical and thermal tests guten tag everybody I'm Stefan and welcome to CNC kitchen even though you can nowadays get almost any thermoplastic as a 3d printing filament PLA ptg and abs are still the most common ones used PLA is the most printed material due to being very easy to print without any significant smell but with the downside of being a little bit brittle and thermally not very resistant abs is slowly replaced by a very similar material which is a si that performs almost the same but with the added benefit of being UV resistant having less warping tendency and lower order PGG has been on the oppressed since a couple of years and is praised for having these of printing of PLA but being less brittle and thermally more resistant but how do those materials really perform in a side-by-side comparison in this there a best material I gotta say at this point that almost every material from every manufacturer will behave differently because even though it says PLA PT G or a si on the box there isn't just one PLA one PT g or one a si depending on the manufacturer the raw material compositions and additives deviate that will influence print ability as well as performance and this is also where there are $10 PLA s as well as $50 PLA s on the market also the printer printing settings and environment change properties I can cover everything but it shows pushes own material line up for a reason because once they cover all of those materials are all really decently priced and due to the amount of QA they perform shouldn't scatter that much from batch to batch or even roll to roll they even check material color to avoid having different use when doing a project where you need more than one roll since Prussia also provides their whole own ecosystem with their original Prussia printers crucial slicer and the crew Sherman it doesn't require me to tune in each material on my own because they already did a pretty good job in that regard and just to be clear this material works just as well on any other printer that also uses one point seven five millimeter filament so what I've done is that I printed quality test parts and real test samples for all three types of perugia Mint and we'll be taking a look at them side-by-side to see how they perform in each of these categories price print ability printing quality static strength and layer adhesion ductility stiffness impact resistance and thermal resistance what materials are you usually using for your projects and why let me know down in the comments all spools come in a nice copper box and are sealed in thick plastic bags that are resealable for storage including some desiccant the spool itself looks unique with a hexagon cutout that don't only reduce material usage flawless weight and shipping costs but also give you plenty of holes to poke the ends of your filament through it features manufacturing data and print settings as well as a QR code that lets you track each single spool produced and provides QC information the only issue I had was with these slots in the center hole that are probably used for indexing during production but which caught on the cheap spool holder that I use on the top of my printing enclosure and that resulted in printing artifacts definitely use a round one here Purusha talked quite a bit about their perfect winding and it really does look nice and should reduce tangles during printing a kilo of pro sherman PLA sells for 25 euros ptg and a si sell for 30 euros though das a spool only contains 850 grams the reason for that is probably not because they are greedy but a si has a density 15% lower than the others so one kilogram of material just won't fit on a spool but since all spools still contain around 330 metres of filament you can still print the same amount in the end that makes a kilo price of 25 euros for pla 30 euros for PT g and 35 euros for a SI taking the density into consideration PT GNA is a both end up at nine cents a meter whereas pla is seven point five centimeter in europe you can directly buy from frohes webstore in the US it's available on amazon including free prime shipping so in the end it's not super cheap but still a very decent price especially for the quality and the range of colors you're getting and especially inexpensive if you compare it to the materials from other 3d printer ecosystems all the prints were done on my original Prussia III Mark V s I printed to print shops with each of the materials one featured quality test parts the other one contains the samples for material testing I use stock settings on the printer and didn't play around with any parameters all prints were done in my office and no enclosure I only did one set of layer adhesion samples with a si and an enclosure down in my basement but since it was winter time it didn't get much warmer than 30 degrees Celsius PLA was printed at 215 degrees Celsius on nozzle ptg at 250 and a si at 260 degrees Celsius because this might also impact layer adhesion and print quality later PLA used the fan of 100% for ptg it was set to 30 to 50% and even a si was printed with 20% cooling fan parts mostly stuck quite well to the P I called spring steel bed but I sometimes applied a bit of magic for challenging prints even though Prussia doesn't recommend the use of these adhesion products overhangs look great up to 55 degrees and started to degenerate at 65 degrees only and remarkably a si printed those still great stringing and small details was also very similar with only the PT G getting a little bit worse right at the tips pla perform the best at the bridging test PT g little worse and this was the only time that a si came last all 3d benches look really good the army green PLA and the jet black PT g had a shiny finish the orange a si which color I actually adore was met the only thing I was able to see was that the PT G was a little stringy which is common for that material and the a si part had a small step on the height of the flow of the 3d Banshee which is a good indication that it contracts more during cooling than the others due to the usage of cooling even the chimney Anya is a part look grade which is often a challenge with this material group all in all that means if you have a good material to start with and tuned it properly PLA PT G and a si can produce gorgeous prints next let's continue with the interesting part and this is the mechanical tests since this shouldn't get crazy technical I compared the static strength of the materials not with standardized dog-bone test samples but printed a couple of my test hooks where we can analyze the material strength of a lying part and the layer adhesion with a hook printed vertically all pots were printed with the same wall and infill settings I mounted the pots one of the other in my DIY universal test machine and loaded them at a constant
Thanks Segolaq your participation is very much appreciated
