INTRO

Below you will find parts and tools, which will help you to assemble enclosure. If you noticed mistakes, have questions or suggestions, please write to [email protected] • Project page: Jocys.com/Enclosure

Maximum temperature inside enclosure depends on temperature of the room and heated 3D printer bed. Stable higher temperature inside enclosure reduces warping and detaching of bigger parts from the plate. Control precision is 1°C. HOW IT WORKS: If temperature rises +1°C above set limit (for example, set limit is +40°C and temperature rises to +41°C), two “MH1210A” controllers start fans (ventilation) and drop temperature to +40°C. Tested temperature limit inside enclosure +46°C (room +28°C, heated bed +85°C, extruder +240°C). In order to achieve even higher temperatures inside enclosure, insulation must be added to windows and door. All enclosure parts (cut perspex sheets, ~2kg PETG filament (20% infill), bottle of Windex, smoke alarm, cables, controllers, etc.) cost me about €260 (tools are not included).

E3D V6 HotEnd is rated to 40°C ambient operating temperature. As you approach that temperature, cooling efficiency is reduced, allowing more heat up past the heatbreak. This can cause low temperature filament to soften in the mechanism to cause feed problems. Therefore, for PETG filament, I set both enclosure fans to keep 35°C inside enclosure.

Parts were printed from PETG with Prusa3D i3 MK3 Printer.

If your printer is not precise enough, printed parts may not fit into each other. To test, if your printer is precise enough, you can print and try to fit into each other these two parts from “Table_3_Leg_Top_Ends.STL” file. Spaces between some parts are 0.1mm only.

1mm spaces between perspex sheets and table are for even ventilation.
2 temperature controller-fan sets are for safety, in case one set malfunctions.

If you made your own updates or (file) changes, related to this project, please send me a link. I will add this link to your work on this page.

PARTS

DUBLICATE SILICONE • OPTIONAL

TOOLS

WIRE STRIPPING AND CUTTING TOOLS

PENCIL

PETG FILAMENT

You will need about 2 kg with 20% infill

I would not recommend to print parts from ABS (shrinkage is too big) or PLA (low heat resistance).

PRINTING SETTINGS

Printing Settings for MCPP BasicFil or AmazonBasics PETG Filament on PrusaSlicer
...for Spring Steel Sheet with Smooth Double-sided PEI

For BIG parts to stick on TEXTURED PEI Powder-coated Spring Steel Sheet sheet, I increased recommended bed temperature from 60-80°C (for AmazonBasic and MCPP BasicFill PETG filaments) to 85°C (First layer) and 90°C (Other layers). I printed BIG parts in already partly assembled Temperature Controlled Enclosure. Temperature inside enclosure was 35°C with these bed settings. E3D V6 HotEnd is rated to 40°C ambient operating temperature. As you approach that temperature, cooling efficiency is reduced, allowing more heat up past the heatbreak. This can cause low temperature filament to soften in the mechanism to cause feed problems.

Modified settings: PrusaSlicer > Filament Settings > Prusament PETG > Filament

• "Extruder: 240°C".
• "Bed: 85°C / 90°C".

Modified settings: PrusaSlicer > Print Settings > 0.20 QUALITY MK3 > Layers and perimeters

• "Ensure vertical shell thickness: disabled" - I had problems with thin 45° hanging angles when it was enabled.
• "Perimeters: 3" - infill pattern is less visible on surface.

Modified settings: PrusaSlicer > Print Settings > 0.20 QUALITY MK3 > Inflill

• "Fill density: 20%".
• "Fill density: 60%" - for door and windows holding parts.

Modified settings: PrusaSlicer > Print Settings > 0.20 QUALITY MK3 > Speed

• Reduced printing speeds (10-20-180-400). Slower speeds results in smoother and glossier surfaces without matte areas, reduces printing noise with vibrations... lesser probability for corners of big parts to unstick from heated bed, because of shrinking.
• "Travel: 180" - low speeds (like 20) creates surface blobs after long travel distances.
• "First layer speed: 10" - for better adhesion.

Modified settings: PrusaSlicer > Printer Settings > Original Prusa i3 MK3S > Custom G-code

• I added few lines to G-code to remove filament blob on nozzle right before printing starts and raised intro line to reduce wearing of steel sheet plate surface.

G0 Z50 ; ADDED LINE - NOZZLE BLOB - Z up 50 mm to clean filament blob from nozzle before printing.
G4 S5 ; ADDED LINE - NOZZLE BLOB - Pause 5 seconds to clean the nozzle.
G0 Z-50 ; ADDED LINE - NOZZLE BLOB - Z down 50 mm to initial position.
G0 Z0.5 ; ADDED LINE - INTRO LINE - Z up 0.5 mm for less intro line adhesion to prevent steel sheet plate surface from wearing.
G0 Y-1 ; ADDED LINE - INTRO LINE - Y shift 2 mm intro line default start position to prevent steel sheet plate surface from wearing.

For better quality and safety... I printed majority of parts separately.
