**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. ====== 3D Printing Materials aka Filament in realraum ====== * [[https://colorfabb.com/filaments/co-polyesters-filaments/ngen|nGen from colorFabb]] * 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 * [[https://colorfabb.com/filaments/co-polyesters-filaments/ngen-lux|nGen-Lux from colorFabb]] * 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 * [[https://www.lulzbot.com/store/filament/bridge-nylon|Bridge Nylon 3mm aka "bridge"]] * 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 * [[https://www.lulzbot.com/store/filament/t-glase|t-glase clear 3mm]] * Colors in r3: clear, red * Extrusion-temp: 230°C * 3mm Spool Length: 56m * //double price// * translucent * brittle * [[https://www.lulzbot.com/store/filament/pla-village|PLA 3mm]] * Colors in r3: deep blue * Extrusion-temp: 195-215°C * 3mm Spool Length: ~125m * //normal price// * [[https://www.lulzbot.com/store/filament/stainless-steel-pla|Stainless Steel PLA (proto-pasta)]] * 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 * [[https://www.lulzbot.com/store/filament/cleaning|Cleaning Filament]] * Color: translucent white * Extrusion-temp: 150-300°C * 3mm Spool Length: ~5m * use only for cleaning and when changing filaments * [[https://www.lulzbot.com/store/filament/hips|HIPS 3mm white]] * 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// See the [[https://www.lulzbot.com/sites/default/files/v2/LulzBot_3D_Printing_Filament_Guide.pdf|Lulzbot Filament Guide]] on print-settings for various materials.

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 ==== for members ==== === in gramm === * //normal price material//: 0.06€ per gram * //double price material//: 0.12€ per gram * //5x normal price material//: 0.30€ per gram === in m for 3mm Filament (Lulzbot) === * //normal price material//: 0.50€ per started meter * //double price material//: 1.00€ per started meter * //5x normal price material//: 2.50€ per started meter === in m for 1.75mm Filament (everything else) === * //normal price material//: 0.30€ per started meter * //double price material//: 0.60€ per started meter * //5x normal price material//: 1.50€ per started meter ==== for guests ==== === in gramm === * //normal price material//: 0.12€ per gram * //double price material//: 0.24€ per gram * //5x normal price material//: 0.60€ per gram === in m for 3mm Filament (Lulzbot) === * //normal price material//: 1.00€ per started meter * //double price material//: 2.00€ per started meter * //5x normal price material//: 5.00€ per started meter === in m for 1.75mm Filament (everything else) === * //normal price material//: 0.60€ per started meter * //double price material//: 1.20€ per started meter * //5x normal price material//: 3.00€ per started meter
