The original MK2.5 desktop extruder has been replaced by the MK3 and is no longer available. You can find the MK3 here.
For sale here is a DIY kit of the Original Desktop Filament Extruder MK2.5 from ARTME 3D. The kit is supplied with two different extruder screws (information can be found in the item description). Please read the Product description before purchasing. This is not a commercial product being sold, but a project for which the hardware is offered here in individual parts. Further items are required to set up and operate the extruder, see below.
Delivery time:
Additionally required accessories and tools:
If you purchase the DIY kit from ARTME 3D, you will need the following material, which is not included in the scope of delivery, in order to be able to set up and operate the extruder:
- The 3D printed components (white parts on the photos) are not included in the scope of delivery and must be printed out yourself. Please see the documantation for the files. You can print the parts during the preparation and shipping time. It is a lot to print.
-
For legal and technical reasons, the power pack is not included in the scope of delivery. Please use a closed desktop power supply (as you know it from laptops). The power pack must have 24Vdc output voltage. The output current must be at least 6 amps. In other words, have an output of at least 144 watts. It may happen that in countries with a mains voltage of 100 to 120 volts the power supply unit does not provide full power. Therefore, I recommend using a high-quality power supply unit for 100 to 120V mains voltage or using a more powerful power supply unit (more than 6 ampere output current). If you have the installation done by a specialist, you can also use open switching power supplies, as known from common 3D printers. However, during installation you come into contact with components that are connected to the mains voltage. Therefore, there is danger to life. Only have this type of power supply installed by a professional.
- An empty filament spool (inner hole diameter 50 to 60mm)
- Required tool:
- Hammer
- dust mask
- Access to a vise is an advantage.
- Rubbing alcohol and paper towels
- Needle-nosed pliers and wire strippers are useful
- Needle
- Scissors
- Electronic caliper to measure the filament diameter (good quality!)
- folding rule
2 extruder screws are included:
- The extruder screw (high compression) is designed for processing shredded 3D print waste from PLA, ABS and PETG. In addition, it can also be used to process certain plastics in pellet form, such as PLA types (optimized for 3D printing) and ABS.
- The extruder screw (low compression) is designed for the processing of plastics in pellet form such as PLA, ABS, ASA, PETG.
-
Other materials such as PP, PA or PE are special cases. These can usually be extruded. However, it is often not possible to calibrate a good filament with this setup. Simply because these materials harden very quickly after leaving the nozzle. Calibration via gravity therefore often does not work. Here you can find information on PP.
-
PET from shredded bottles is also a special case. You can find information on PET here.
-
Softer materials like TPE and TPU often work with both extruder screws. But I haven't tested it very much. So I can't guarantee it.
- Very heavily modified materials such as PLA+ and materials from "Extrudr" often cannot be processed with this extruder. These are modified in such a way that the melting behavior does not fit into this system (softening quite late and then immediately becoming thin).
Skills and Difficulty:
Building this extruder is a little more complex than building a 3D printer, for example. Among other things, the following activities are to be carried out:
- The printing of a large number of parts (possibly several days of printing time and approx. 1.8 to 2 kg of material consumption)
- Reworking 3D printed parts.
- Electronics wiring
Workload:
Depending on your experience in building such kits, you should allow between 7 and 16 hours for assembly.
Scope of delivery:
