The Pro series line of product is designed to push the reliability to a whole new level. Every small feature has been redesigned from bottom-up from based on the feedback we received and our own experience.<\/p>\n

The 3d printer hotend’s heater block undergoes a massive amount of stresses: thermal stress from the heater, pressure stress from the extruder and tension stress from the nozzle. With our intensive tests with high-temperature materials such as PEEK, PEI (Ultem) and PSU, we have realized that this component required a rethinking.<\/p>\n

Understanding materials<\/h2>\n

The first step when designing a part is to choose the right material. There are a ton of different alloys available out there, and they all have their advantages and application. When choosing, you need to identify the key characteristics you\u2019ll be evaluating. In our heat block case, we\u2019ll want:<\/p>\n
