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.
Unpacking:
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.
More on PETG:
For more info on PETG take a look at this previous review of fiberlogy PETG filament.
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.
Fiberlogy Filament Vacuum Sealed
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.
Fiberlogy Filament on fixed spool
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).
Before loading the filament for the first time, weigh the loaded spool (1.175Kg) and subtracted the filament weight of (850g) to get the spool weight of (325g).
This is can useful for calculating the remaining filament weight for future prints.
Test:
As with all new filaments i confirm the real diameter with a caliper at 4 points over the first couple of meters.
The result was( 1.74+1.76+1.75+1.74)/4= 1.7475mm Average real diameter.
You can use this to create a new filament profile in your favorite slicer and adjust the filament diameter to suit.
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.

Verdict:
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).
Benefits:
High durability
Low shrinkage
Resistance to acids, salts, alkaline substances
Strong layer adhesion
Weather Resistant
*Food safe
*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.
For even more on PETG filament check out Thomas Sanladerer’s excellent video below.
Looking for something different? See our list of currently available filaments here.
Most of my crimping experience is with larger cables and terminals. When it came to repair or make the odd non critical smaller terminal i would attempt to compress with pliers and solder, not ideal.
Faced with the task of having to make and repair several different terminals for a 3D printer i realized the need to invest in a pair of suitable crimping pliers.
These terminals included 6 way female JST PH 2.0mm connectors for the stepper motors and 2/4way Mini PV (Also called Dupont) with a 2.54mm pitch for connection to a ramps 1.4 board.
LEFT: 2&4way Mini PV (Dupont) with a 2.54mm pitch, RIGHT: 6 way female JST PH 2.0mm
When i searched for a specific JST PH crimper i came across the official WC-240 JST Crimper. At an eye watering £337.99 this was out of the question.
Official crimp pliers are available for every different type of connector and can be very expensive. I turned to find a pair of budget generic crimp pliers capable of handling 24AWG cable and the connectors above.
What is available and where?
After a short browse of generic crimp pliers i found the Engineer PA-09 Mirco connector pliers. Capable of crimping 80 different terminals 0f 1.25-2.5mm pitch and 32-20AWG cable, just the ticket.
Engineer PA-09 Crimping Pilers
The PA-09 micro connector pliers are 175mm long, carbon steel construction with a Elastomer (TPR) cushioned handle and are made in Japan.
This all sounded promising, without a local shop/supplier i found them listed on amazon at a very reasonable £39.99. *Available HERE.

Testing the PA-09 Crimping Pliers
After a very quick delivery, i put them straight to the test. Removing them from the Japanese text covered packing the quality is immediately noticeable.

They feel nice in the hand and the hinge mechanism is smooth with an adjustable screw
PA-09 Details

Manual Page 2
Following the instructions provided, i started with with the JST PH connector. Firstly inserting the striped wire into the crimp and crimping the conductor.
Secondly, re-positioned to the next size die and crimp the insulation.
Finally to get a smooth entry into the connector housing, i pressed the terminal between the end of the pliers jaws. Repeating the process for the other conductors.
6 Way JST PH 2.00mm connector
For the Mini PV/Dupont connectors, just select the correct die and follow the same procedure. I found that helping hands(a stand with clamps) useful to hold the wire in place whilst carrying this out.
LEFT: Completed Mini PV/Dupont RIGHT: Completed JST PH
The Verdict
My overall opinion of the PA-09 is that they well made, good value and capable of making accurate and reliable crimps for many different terminals.
The versatility and cost of these crimp pliers will help save time from bodged terminals and money spent on made leads, a winning combination and a sure tool to turn to in the future.
Crimping larger cable and terminals?
If you need to crimp larger cable and terminals, the ENGINEER pa-21 is suitable for AWG28~AWG18 with 1.6mm, 1.9mm, 2.2mm & 2.5mm dies. Both variants are listed below.
