My short summary of filaments in the UK is based on my own experience guided by the kind contributions from contributors above. This may be an unfair comparison as I am new to 3d printing and I was comparing different colours which does affect PLA properties so take this at face value. All the filaments I tried were good, but some were better. The combination of being low in UV and temperature resistance means that it’s not ideal for outdoor use. Also, PLA is only soluble in chemicals like chloroform or hot benzene. So when connecting multiple pieces, you’re better off using just glue. Interestingly, I did need to run my printer bed and extruder temperatures about 5 degrees higher than recommended on all my filaments and I question whether this may be a printer specific. Certainly the default settings on Slic3r PE are quite high. However, PLA is not a perfect material and, just like every other plastic, has some disadvantages. The low melting temperature also means low-temperature resistance. Parts start to lose mechanical strength at temperatures over 60 °C.

The G in the acronym PETG stands for Glycol which is added during the manufacturing process. Glycol modifies the properties of PET, so that it’s easier to print, less brittle and clearer when printing with semi-transparent variants. PETG has a low thermal expansion, so even when printing big objects, and without an enclosure, it rarely lifts from the bed and warps. In addition to that, PETG is ductile . It has a healthy amount of flex which can prevent parts from breaking under pressure. Amongst the Benchys, I also ran 3 cube/vase mode prints to get the extrusion multiplier just right, did another Benchy, but still couldn’t eliminate the stringing. The team at Prusa Research have made something special with the MK3. If you only ever own one printer, make it this one. Of course, once you buy it you will want more of them, and that's ok too. – Windows Central Review In the photo below, from left to right the temperatures are 193, 195, 205, 210. The 193 version completed and had seemed to have the least amount of stringing, but split along the bottom when I removed it from the plate and showed signs of under extrusion/layer separation), I didn’t grab a photo of the 215 version, but I couldn’t see any noticeable difference between it and the 210 version.

We tested it using its default settings and found it extremely capable. Its print quality is truly exceptional and it’s an easy-to-use, straightforward machine. – All3DP MK3S Review Of the 11 printers we have tested over the past five years, the Prusa i3 MK3S printer has produced the largest and best-looking prints. – THE NEW YORK TIMES REVIEW Not sure if our filament is right for you? Don't worry you can just buy an Ooznest Materials sample and give it a try, we guarantee you won't be disappointed with Ooznest Materials.

The preassembled version of the Original Prusa i3 MK3S is a cinch to get up and running, is easy to operate, and has a good slicing program. It produced consistently beautiful prints in our testing, with no misprints. – PC Mag ReviewI was given an unmarked 1kg roll of silver PLA with my printer, presumably Prusa PLA which is now superseded by Prulament, a filament not yet available in UK, unless shipped from abroad at significant cost. This roll was not bad, did some nice builds with it but with occasional unexpected fails. When successful; the finish was brilliant, my Masterspool print looks immaculate. I got a lovely first layer 75x75 square right off the bat, with only minimal adjustment to the Z-height, so ran a Benchy. This is where I hit problems with stringing. To cut a long afternoon’s story short, I played with different temperatures from 190 - 215, although the 190 print didn’t look at all right, so I abandoned it at the point the gyroid infilled pattern stats printing. If you can handle the oozing and strong adhesion, you’ll be left with a very durable print, that is considerably temperature resistant and usable for both indoor and outdoor use. When printing with PETG, you must consider using a cooling fan. The rapid cooling helps to keep print detailed with no stringing and blobs. If you need the strongest possible print, print with no fan. The higher filament temperature will aid extra strong layer adhesion. We recommend printing the first few layers without the cooling fan to prevent warping and half fan power on after that. Number of perimeters & strength Normally filament is wound onto plastic spools. We recognised that winding 3D Printer filament onto a plastic spool is completely unnecessary. All our Ooznest Material filaments are wound onto a 100% recyclable cardboard spool. Our cardboard spools are extremely rigid, they will not twist, deform, or tear from repeated use.
