![]() ![]() In addition with find a silicone sock for the heater block itself, and a fan guard. The silicone stepper motor cable is supposed to be able higher temperatures, though I wonder why the fan cable isn’t also silicone. Silicone stepper motor cable, regular plastic fan extension cable, and a 70W heater cartridge. In the large white box next to black foam, we find several accessories: It is not immediately obvious what its purpose is. We also find a JST-XH 4-pin connector with inserts to be crimped to a cable. This will be a challenge for me, as I don’t have any printer that has boards available that support stepsticks. The chip is put on a stepstick, which fits into any board with stepstick slots (boards with replaceable stepper drivers). The MAX31865 chip contained in the packaging is a requirement for measuring the temperature of the PT100 thermistor safely. The thermistor amplifier chip is kept safe by foam packaging Next to the H2 extruder, there is a small black box. When we open the box we’re greeted by the manual.Ī part of the H2 extruder already peeks through What’s inside? Top of the box - notice the warning about the high body temperature of the extruder at high temperatureīIQU must have hired an designer that worked at Apple □ - the packaging looks very attractive! The packaging self is shrinkwrapped in plastic foil. The H2 500☌ comes in a rectangular white box, with plenty of protective foam inside. And yes, that on the right is PEI - what you might have used as a build surface. The most well-known filaments on this list might be Nylon (PA) and PC (Polycarbonate). As a suggestion, BIQU left a helpful list of filaments you can print thanks to the higher temperatures. Not bad!Īs mentioned, the hotend assembly is rated to go up to 500☌. The assembly uses a PT100 temperature sensor together with a MAX31865 amplifier for accurate temperature reading capabilityĬompared to an regular BIQU H2, the high temperature variant is about 10-20 dollars more expensive.The stepper motor is tolerant of temperatures up to 180☌.The default nozzle is made of high temperature hardened steel.The heat block is made of an nickel plated copper instead of regular aluminum.When it comes to high temperature printing, these features specifically apply to the BIQU H2 500☌ Extruder: In this article I’Il do an initial unboxing and first look of the device and its internals.įor a general description of the features of the H2 direct drive series, including its very low weight, you can refer to my earlier review of the H2 v1.0. ![]() For purposes of review and testing I have received a unit from BIQU. This is a variant of their BIQU H2 direct drive extruder v2.0 of which v1.0 variant I wrote a review earlier. BIQU wants to enter the market for high temperature printing and has release the BIQU H2 500☌ direct drive extruder. ![]()
