DKT LCD 5.5'' 2k/4k 3D printer

thingiverse

This is a 2k/4k 5.5 '' LCD 3D Printer Project for High Speed Printing. The project features semiautomatic leveling of the build plate, an LCD cooling system, and protection for the LCD screen by default in the printer design. To reduce vacuum forces, equalizing air pressure on both sides of the LCD is done to balance the airflow. The size without a power supply unit (PSU) is 300x300x428mm (XYZ), with a build area of 119x66x155mm (XYZ). Needed things and assembly order can be found at https://www.youtube.com/watch?v=X185ppNmLT8&list=PL0jXMDcb7_SD23YF-uyGPE94NsETmnMbk. CAD files in AutoCad 2013+ format for CNC and laser cutting are included, along with an example BOM list in MS Excel format with links provided. The project is designed to have the power supply unit outside, as placing it inside will disrupt airflow and cooling. The site of the project can be found at http://www.dkt3dprinters.com/. Any tips or donations are welcome. Thank you in advance. May 27, 2017: Some updates were made: - Added 0.5mm to each side of the 3mm aluminum build plate piece. - Found only 3mm LED plexiglass in my country; reworked the Plexi cover for 3mm panels. - Changed M3 bolts for plexiglass cover and its two hinges from 12mm to 10mm, but it's not a big deal if you don't. May 28, 2017: More additional information was provided: - Additional drilling is needed on the MDF panel assembly. Use a 2.4mm drill or enough pressure to tighten the screw directly without drilling. - The steel plate should be painted in satin or matte color. - All printed parts receiving direct light from the LED array should be printed with red, green, or orange filament. May 31, 2017: So... LED plexi is not very suitable (too dark - almost no transparency). Bought some green fluorescent molten plexi - close to twice the price of LED one... ~20$ for the piece needed for LC. BOM list file reuploaded with more precise prices. June 2, 2017: Some new pictures were added: - All small 3D printed parts (ABS printed); - Steel plate + 2 small steel pieces + all nuts, bolts, washers; - Inside panels; - Drawer; - Front and side panels; - Back panel stuff; - Comparison with my small and my Delta printer.
