The J-Head Lite V2 Ultimate Economy RepRap 3D Printer Hot End by ohioplastics

Last crawled date: 4 years, 1 month ago

This is the first and only $20 fully assembled hot end. The V2 is the first commercially viable hot end that people can actually afford. It combines the holder of the J-Head, the heat sink of the Arcol, and the hot end of the MK7.We're pushing the envelope of design and thermodynamics to bring 3D printing mainstream.

Specifically designed for 1.75mm filament, This design extrudes PLA and ABS, as well as many other plastics. The extruder can heat up to 250C. It sports the Honeywell 100K ohm thermistor for accurate temperature readings. Unlike all metal hot ends, this design uses passive cooling. It does not require a fan.
