![]() I’m happy to say that I’m now equally as proud of the product after this monumental effort. I’m so proud of the team for pulling this off in such adverse circumstances, while still ensuring that we got prototyping, testing, and scaling done right. By diving deep into the minutia of heat-treatment atmospheres, automated grease dispensing robots, and multi-axis machining, we’ve been able to fix everything that was holding us back. “We’ve spent months painstakingly unpicking the bottlenecks in our manufacturing process that were preventing us being able to make an incredible extruder consistently at the scale we now operate at. Sanjay, who is more excited than anyone to get Hemera back on the shelves, had this to say: Our hardworking production team have expanded capacity with an entirely new production floor (during a pandemic!) to keep up with demand, and our dedicated quality assurance team have been working overtime to make sure all units arrive in your hands in top condition for the best 3D printing experience possible. Supply chain roadblocks exacerbated by COVID-19 have been resolved, enabling us to keep up continuous production and supply of Hemera. Our talented engineering team have put in 19,500 hours (that’s approximately 2.23 years) of drivetrain testing in parallel to get to this solution, and have developed new processes, including commissioning a custom designed grease dispensing robot for more streamlined and accurate unit assembly. We’re happy to report all issues reported to us have been addressed. Thanks to the global pandemic, we also faced huge lead times to obtain samples and then test them, even when processes were accelerated to the max. We’re determined to deliver reliable, premium-quality 3D printing products without compromises, so we’ve spent considerable time revamping our production processes to make our latest units robust against issues that some of the last batches encountered. It’s no secret there were some teething troubles with previous iterations of Hemera. We realise it took a while to get to this point. Hemera features convenient T-Slots for easy mounting to your printer, plus space for other accessories, part cooling fans and bed levelling probes to name a couple.Thanks for bearing with us. This exceptional filament constraint also has a significant impact on printing rigid, and semi-rigid materials such as PLA or Nylon. You won’t experience the full extent of its unrivalled filament constraint until you print ultra-flexible materials. Hemera constrains filament like no other extrusion system, fact. It has a custom motor which is based on a NEMA17, along with our own faceplate designs which has allowed us to add our own features for user convenience, such as mounting slots as well as produce a very compact system. Hemera is a system of components designed to work seamlessly together as a single compact product. ![]() The secondary gear shaft is on a moveable, sprung idler which allows the user to adjust filament tension. ![]() For E3D Hemera, we opted for a hardened stainless steel dual-drive arrangement which provides a huge boost in grip over single drive systems, in fact, we’re able to push filament with up to 10kg of force. ![]()
