Use Cleaning Filament when changing to a filament with a different extrusion temperature.
Otherwise lower-temp filament will charcoal inside the hotend at higher temperatures which can obsctruct the hot-end and create back-pressure and can be almost impossible to clean out.
The Prusa MK4 provided by mkg
Printing on the Original Prusa MK4, provided by member mkg, has the following costs:
- 10 cent / 1 g for your own filament
- 4 cent / 1 g for filament provided by mkg
For convenience, just pay 10€ per every 1kg of filament you get for printing in realraum. Payments are to be put into the cylindrical container next to the 3D printer in LoTHR labeled something like “3D-Druck Spende”.
mkg: PSA. If you use your own filament it’s 1ct/g, using mkg’s filament 4ct/g total Just ask mkg if unclear.

3D Printing Materials aka Filament in realraum
-
- Colors in r3: Black, Purple, Silver (,Blue if you ask DDD)
- Extrusion-temp: 230°C
- 2.85mm Spool Length 750g: ~95m
- 2.85mm Spool Length 2200g: 270m
- normal price, only slightly more expensive than ABS
- least warping so good for precise prints
- sticks really well to printbed
- recommended for big and precise prints
-
- Colors in r3: Yellow
- Extrusion-temp: 230°C
- SORRY only samples in r3
- IF YOU USE A SAMPLE: document result using photos!!!
- expensive price
- like nGen
- recommended for prints where layering should be hard to see
-
- Color: translucent white
- Extrusion-temp: 230°C - 240°C
- 3mm Spool Length: 62.7m
- normal price
- awesome material durability and strength
- needs glue and no printbed heat to stick. even so has tendency of warping on large ground surfaces and thus getting loose
- recommended if cheap, small or very durable prints are needed
-
- Colors in r3: clear, red
- Extrusion-temp: 230°C
- 3mm Spool Length: 56m
- double price
- translucent
- brittle
-
- Colors in r3: deep blue
- Extrusion-temp: 195-215°C
- 3mm Spool Length: ~125m
- normal price
-
- Color: steel gray
- Extrusion-temp: 195-220°C
- 2.85mm Spool Length: ~30m
- 5x normal price, since it's really expensive to buy
actually more than 10 times as expensive as HIPS per meter. - brittle on small features but durable like PLA and heavy on bigger pieces
- sticks really well on printbed. do not use glue or can forget about getting your print off the bed
-
- Color: translucent white
- Extrusion-temp: 150-300°C
- 3mm Spool Length: ~5m
- use only for cleaning and when changing filaments
-
- Colors in r3:
white - Extrusion-temp: 230°C
- Spool Length: ~140m
- normal price
- nice material strength
- warps on large surface area
- needs raft for less than 4cm² ground surface
- PLA 1.75 (for Witbox)
- normal price
- Colors in r3: blue, …..
- Extrusion-temp: 220°C
- ABS
- normal price

Cost and Prices
- Cost is per meter filament (2.85..3mm ø)
- Experimental: Cost per g (As we have different filaments widths, this is an attempt at simplification)
- if g and m cost disagree, choose cost per m or the average between the two at your discretion
- calculated for NGEN. Probably not as applicable for other materials yet.
- Cura (or slicer of your choice) tells you how many meters and g you will need
- We pay per started meter. e.g. you upround
- Please feed the cat next to the printer with the € before printing
