800 yuan assembly of a 3D printer full tutorial process-parts list

Follow the previous tutorial to assemble a 3D printer for 800 yuan

K800 is a low-cost 3D Printer Based on kosselmini. It reduces the cost by changing the design, but reduces the performance and cost-effectiveness.

The main changes are:
Change the base bracket to-General Bracket
Change planetary step to-"proportional gear step"
Change the straight-line slide to-> slide
Fish-eye Joint Parallel arm-"high-intensity parallel arm

 

Motor part:
43mm long 42 step motor X4, 42 step for k800 (kosselmini) 3D printer "driver" and "Wire Feed" work. The price of a certain treasure is about 45 yuan, which is responsible for the 42 steps of "Wire Feed". If the requirement is relatively high, you can purchase a price of 63mm long, but the price will increase by 20 yuan.

Extrusion head part 2:
Hot extrusion head (extrusion head, Print Head, nozzle): hot extrusion head is an important part of 3D printer, whether the silk is smooth and cooling capacity is often related to the quality of the printer. At present, the inner wall of Teflon is used in the extrusion head, so the blockage problem is improved. An open-source 3D printer generally consists of "4mm diameter extrusion head" + "Heating aluminum block" + "Heating head" + "K thermistor" + "Iron-fluoride pipe" + "aluminum heat sink" + "Direct Connection, you can purchase the hot head separately or directly. K800 needs a 75mm-wire remote extrusion head, and the basic length of the wire is 50 cm (standard )~ 1 m (long) left or right.

Aluminum Profiles and non-standard parts:
The overall kossel800 frame consists of "Aluminum Profiles" and "non-standard parts. Standard k800 aluminum profiles use 2020 GB aluminum profiles. The size required is 24cmx9 and 60cmx3. The crowdfunding extended edition requires 24 cmx9 and 68 cmx3 2020 GB aluminum profiles. Basically all are in the 13 ~ About 15 yuan a meter, will not be much worse, the trough of the National Standard aluminum profile is relatively narrow, so it is suitable for walking around the pulley. Of course, the European standard can also be, but the pulley is relatively rough, and the special nut is more expensive. The aluminum profiles must be sent after being cut by the manufacturer, and the manufacturer must be accurate in cutting. The cutting accuracy must be +-0.3 ~ Within 0.5.
