Original Desktop Filament Extruder MK3S and MK3S+ by ARTME 3D

Attention: 

1. These files are for version MK3S light, MK3S and MK3S+. Please check which hardware you have!
2. Please read these instructions completely and carefully. The requirements must be followed therwise the function of the extruder may be impaired.

The Original Desktop Filament Extruder MK3S and MK3S+ is a commercially certified complete kit from ARTME 3D® Home - ARTME 3D (artme-3d.de). The kit is supplied with all the necessary components, including a power supply unit with country-specific power plug and multilingual control unit. Only the 3D printed parts need to be printed yourself. The difference to the previous model MK3 is a higher output rate a filament measuring device and the option to use a geared stepper motor instead of the 3D printed gear, if you run 24/7.The MK3S and MK3S+ are plastic extruders in an unbeatably small but powerful design for the production of 3D printer filament. The extruder works with a stainless steel extruder screw with compression zone. This allows the extruder to process commercially available plastic pellets and also regrind from 3D printer waste. The filament produced is wound directly onto a spool. And all this with a footprint of just 509 mm wide and 406 mm deep.

Print order and settings:

Please see the PDF files in the “other files” down below. In this table, the order of the components is shown so that it corresponds to the assembly sequence. There you also find the settings and additional Informations like needed support structure or optional parts. The parts marked with PETG are subject to high mechanical and/or thermal loads during operation. These must be printed in PETG as a minimum.

Printer requirements:

The parts are only intended for FDM printing. The print quality and dimensional accuracy must be good. The printer must be well aligned and the axes must be at right angles to each other. The Z-seam must be of good quality and must not create holes or nubs on the surface of the parts, otherwise the function of the parts may be impaired and extensive reworking will be required. The print bed of the printer must be at least 200x200mm in size.

Find your way around the print files:

All 3D-printed parts have a unique designation as a combination of letters. The first two capital letters indicate the part group. For example: The two initial letters of the component ED-B are derived from the English "Extruder Drive". The breakdown of the parts for the "Extruder Drive" can then be found in the PDF files in the “other files” down below.

Color selection:

The choice of color is up to you. However, I find the color white the most stylish. In combination with the black aluminum profiles it looks like a real machine, in bright colors it looks more like a toy. The SO-D part must be printed in white (opaque, not semi-transparent) to fulfill its function, but this part is included in the kit from ARTME 3D®.

Printing time and material requirements:

The printing time can take up to several days. You should expect a material consumption of about 2 kg.

Optional components:

You must select the file that is suitable for printing from the files that contain the note "Option" in their part-name:
 

The parts GE-C, GE-F.1 and GE-G.3 have a hole with a diameter of 12 mm. When FDM printing such a part, the bore is usually smaller than it needs to be. For this reason, there are several variants of parts with a larger hole than 12 mm. For Prusa printers, the files with the 12.2 mm hole usually fit well. For Prusa printers for example, the files with the 12.2 mm hole usually fit well. (As an example, the name of the print file in this case is GE-C-option-12.2mm.stl). It must fit tightly, if the hole is too large and too loose, this can have a negative effect on the function. You need to know your printer, if in doubt print a test piece to see how small the diameter will be. The reason for this is that a metal shaft must fit into the hole. It must not be able to be pressed in too tightly, but it must not be too loose either. This is explained in detail in the assembly instructions.
 

The ED-A part also has a hole with a diameter of 12 mm. When FDM printing such a part, the hole is usually smaller than it needs to be. For this reason, there are several variants of the ED-A parts with a larger hole than 12 mm. For Prusa printers, the file with the 12.3 mm hole usually fits well. We need a loose fit. So the parts must be able to move a little during operation. So if the hole is too tight, it can have a negative effect on the function. You need to know your printer, if in doubt print a test piece to see what the diameter will be. The reason for this is that a metal shaft must fit into the hole but remain easy to move. However, the connection must not be too large and loose either.

For the SH-G part, you must select the part that corresponds to the inner diameter of the filament spool you are using.

For parts FG-O and FG-P, you must select the part that corresponds to the size of the filament spool you are using. FG-O for spools up to 1 kg. FG-P for spools up to 2 kg.
