I purchased this 3d printer before Christmas and have printed around 200 parts for our O2 system, bulkhead nipples, mask nipples and CPAP hose couplers. It has printed flawlessly every single part with no aborts or damaged parts. Parts that cost me $3 are now less than $0.50 including the cost of the 3d printer. I recommend this 3d printer very high, 5 stars. TJ
