If you’re interested in a machine capable of serial production and don’t mind spending some time learning how to get the best results from a machine, the Creality CR-30 will likely be a good fit for you. If you are uncomfortable with making adjustments to the hardware of the machine or otherwise want a printer that is simply easier to use, an FDM printer like the Prusa MK3S+ will be a better fit.
Perhaps it was the flashy video bigging up 250 mm/s and the promise of blistering fast printing, but we’re left feeling a little underwhelmed by the Creality Ender 7. Sure, it can print faster than many similar desktop 3D printers in some circumstances without completely giving up on print quality – that’s good – but for over $700 of 3D printer, it doesn’t seem like there’s all that much here. There’s pricier hardware like linear rails, beefier stepper motors with microstepping drivers, and Gates timing belts to accommodate the CoreXY motion system, but ultimately the Ender 7 is a printer of similar caliber to the company’s previous machines – not necessarily better. It can print faster than others, yes, but not necessarily at the same level of quality – the machine doesn’t quite live up to the marketing.
