I've recently discovered that a lot of trouble I've been having with my Ultimaker 3E when printing with PVA support that has been due to the PVA absorbing moisture from the air. I live in the Pacific Northwest and in the wintertime the humidity is very high most of the time. I stored it in an airtight bag, but apparently that wasn't good enough. The PVA has been popping and crackling during printing, presumably due to vaporizing water in the hot extrusion nozzle. Printing results have been very inconsistent, but got immediately better when I swapped in a new roll of PVA. I tried drying the old PVA roll in a food drier at 125 F for 12 hours and when I tried printing with that roll I obtained much better results, but it still wasn't as good as the fresh PVA. There was still some popping and crackling and the extruded support looked "hairy," i.e. not quite that clean. Has anybody had success with rejuvenating PVA that has been exposed to atmospheric moisture? Can you share any tips you have? Thanks in advance.
Embodi3D blogger Paige Anne Carter recently posted an article about medication-infused filament that is being developed. While this can be used for making pills, where I see the greatest potential is in medical devices. I use intra-arterially injected doxorubicin drug-eluting beads as part of my medical practice to treat liver cancer. Cardiologists have drug eluting stents to treat coronary disease. Gynecologists have hormonal IUDs like Mirena. What future medical devices and implants can be made with this new technology?
