Been using this printer for few months now. Started printing out of box, no calibration was needed. Just load the files and it prints. Thanks for the well calibrated machine. Also the tutorials available made it easy to operate without any hassles. Got my doubts clarified before purchase, would recommend this product over others available on the internet. I feel that I have made a right decision to go with 3DPrintronics. Hope to have same level of support in the future.

- Great product
- Great service, dependable machine
I've been using the printer for the last 2 years. I'm not someone who takes very good care of his tools but this machine has held up very well. I've printed prints that lasted upto 48 hours. Other than the occasional lubrication I've had to do no maintenance and the seller is very cooperative and makes spare parts available whenever you need them
Vipul R.Vipul, Thank you for taking out time to share your experience with our 3d printer. We are thrilled to know that it has been working well for you from 2 yrs. We assure you of our continued support and commitment to quality. Happy 3D Printing!

AA.jDear AJ, we thank you for your review of our 3D Printer. We assure you of continued support of our machines.
Visheshfrom 3DPrintronics - As good or better than the Original MK3S
I have four Prusa MK3S and two of those are Bear Upgrade machines. I print large multi day prints on a daily basis. I can confirm that these machines are as good or better than 'Original' Prusa in many parameters. They are workhorses and the support provided by 3DPrintTronics is exemplary. There's a whole support community WhatsApp group that solves most of your issues in an instant. It's also important to note that these printers effectively don't get outdated since they can be upgraded part by part. You are also part of the fanatical worldwide Prusa community. I have attached two videos of a typical print that I do. It's flawless and a 59 hour (PLA+), 23 hour print (Petg)

Do we get both glass and magnetic plate with the printer?
Hello Vinod, Prusa i3 Mk3s uses only Spring steel plate for printing. You can't and there is no need o using glass plate on this printer. We do not provide glass with it, only spring steel plate is provided
Is auto bed levelling feature present like original prusa?
