Prusament filament as you might have guessed is manufactured in house by Josef Prusa. Prusa Research is the only 3D printer manufacturer with its own filament production lines.
Prusament filaments are available in PLA, PETG and ASA in a range of colours. See more about Prusament filaments in the video below.
The filament comes in a resealable vacuum sealed bag supplied in a sealed cardboard box. A specification label including a QR code for details and a date stamp is located on the side, this filament was produced on 16.9.2019 less than 1 month old when delivered.
The filament is perfectly wound on a ‘honeycomb’ patterned spool that results in 45% less plastic being used. There are filament catches around the perimeter and another QR code stamped on the spool.
A great thing about Prusament filament is the amount of detail accessible via the QR code or ID, a sample spool can be seen here. Amongst other things the exact weight of the filament and spool are available including a calculator for working out the remaining length of filament left on the spool.
The graph displays the tolerance range confirming it is within ±0.02mm along its entire length. This is reassuring and will provide quality printing throughout the spool.
The first print of a calibration cube at 0.2mm layer height came out great, good layer adhesion and the colour is identical to the printed parts found on a Prusa printer.
As expected the Benchy above turned out very nice, with only some slight stringing which is a characteristic of PETG in general.

Where to buy:
Prusament filament is available from Prusa Research’s official Josef Prusa shop shop.prusa3d.com.
A 1Kg spool of Prusament PETG in Prusa Orange cost £26.69 inc tax. Delivery to the UK which took 7 days and was £5.71 bringing the total to £32.40 delivered.
Established and operating in Poland, Fiberlogy uses German machines and high quality raw materials, producing materials with a diameter tolerance of +/- 0.02mm and oval tolerance of +0.01mm. You can find out more about them here.
Fiberlogy PETG and comes supplied vacuumed sealed with a clay sachet in a windowed box.
The box is stamped with a serial number including the date of 21/12/2018, assuming this is around the date of manufacturing would make it less than 12 months old.
The black PETG has a satin like appearance and the filament has a slight texture.
Pre-wound on a rather different looking fixed spool, it is also available as a “re-fill” for a lower price.
The re-fill can be loaded onto a “masterspool” available here. (Check sizes).
The calibration cube is a quick and simple print to establish any basic problems that may present themselves later.
Moving on to the Benchy, it preformed very well with good layer adhesion, bridging and only some slight stringing. Both where printed with 0.2mm layer height on a Prusa i3 MK2.5S.
After the successful calibration prints of the Fiberlogy PETG, i got down to business with printing some parts for a Colido bowden conversion. This included a j-head hotend carriage and extruder which can be seen below.
I had a great first experience with Fiberlogy PETG, producing high quality strong functional prints.
I do like that Fiberlogy offer these filaments as a “re-fill” to reduce the waste produced from spent spools and save money at the same time!
Where to buy Fiberlogy PETG:
Fiberlogy PET-G Black 850g is available from but not limited to the following:
shop.3dfilaprint.com £26.10 inc VAT, FREE UK delivery and a filament storage bag. I also received a free 10M sample of black Alloy 910 HDT by taulman 3D, very nice.
If you opt for the refill, it can be loaded onto the “Master spool” available here, which could be then used to load already spent spools?
More on PETG:
The PETG filament is a copolymer, basically Polyethylene terephthalate (PET) what is used in plastic bottles, modified with glycol(G).
Resistance to acids, salts, alkaline substances
Strong layer adhesion
*Check with manufacture. See technical data sheet PDF above.
PETG offers many of the benefits of ABS such as strength and heat resistance without many of the drawbacks, including printing difficulty and odour.
PETG is hygroscopic which means it will absorb water. To preserve the filaments lifespan and quality it should be stored in a cool dry place, ideally in sealed environment.
Printing small parts in the center of the bed may lead to bed thermal runaway. This is something i experienced when printing these shelf pins on a Prusa MK2.5S. I resolved this by printing more at once and positioning them away from the center. You can find out more about this at Prusa3d.com.
