E3D’s Drop-In ObXidian Hot Ends Are a Fast Way to Get More Speed from Your Bambu A1/A1 Mini
The hot ends release in a punchy new purple colorway that, as well as add a splash of color, boost the peak performance of your budget Bambu machines.
For all the various aftermarket hot ends available for Bambu Lab’s machines, only E3D’s are “officially approved” third party accessories, meaning there’s a stamp of confidence in the company’s products. The latest products to get the nod of approval are a pair of ObXidian hot ends for Bambu Lab’s budget A1-series printers.
The E3D High Flow ObXidian comes in 0.4 mm and 0.6 mm variants, with the nozzles integrated into the heatsink with magnets for alignment, just like Bambu Lab’s own nozzles. They are drop-in replacements.
Both nozzles are currently available from the E3D webstore for £55 (approximately $74) or through resellers. It’s worth noting that E3D pays royalties to Bambu Lab to produce compatible parts to the company’s spec, and Bambu Lab donates 50% of that fee to the E3D’s Sanjay Mortimer Foundation charity. So buying one of these nozzles does a little good, too.
What Do They Do?
ObXidian is, basically, the branding for E3D’s special abrasion-resistant nozzle makeup, meaning the new nozzles extend the A1 and A1 Mini’s printing performance to confidently cover fiber-filled filament without sacrificing a nozzle to wear and tear.
The nozzles are non-stick, using E3D’s cleverly named E3DLC (diamond-like-coating) to prevent stray filament build up and make the nozzle easier to clean. They have an internal structure that E3D says can boost volumetric flow rate by 70% over stock values. The practical implication of this is that the performance ceiling for all the stock values of your filament profiles goes higher, meaning peace of mind never having to check or consider tweaking them. Alternatively, it gives you the freedom to pursue faster prints by pushing more filament through the hot end.
E3D is transparent in stating that even these tough nozzles will eventually wear out, given enough printing of abrasive filaments, but they should dramatically outperform the lifespan of regular hardened steel nozzles, the company says.
