The last few days I’ve been trying to get some test prints out of the B9 Creator I bought back in September. To say its been a challenge is an understatement, however the support and help I’ve received from the B9 community has helped me progress from tomato soup to something physical.
The B9 Creator uses a DLP projector to cure a photopolymer (light initiated) resin. The 3D print is sliced in the desired Z axis size, in my case 30 microns, each slice is then projected into the resin through a ‘window’ in the bottom of the resin vat. The z axis build table steps up out of the resin as each layer is cured. Once I’ve worked out how to calibrate properly and the optimum settings have been fathomed, it should be capable of some pretty mind blowing results.
However, at this point my first prints were a complete failure – nothing curing in the resin at all, nothing floating around. Experimenting with higher exposure settings resulted in some layers appearing, but they’d detached themselves from the build table and were floating around in the vat.
After some more hair pulling I’d realised I’d calibrated the build table wrong, then retried with the higher exposure settings and voilà! Something was created, just visible on the base of the build table under the excess resin. There are a number of post print steps that need to be carried out, removing the print from the build table, cleaning with 70% isopropanol, putting into an ultrasonic bath and curing in a UV oven.
Once I have some decent prints to share I’ll explain a little more of the process, in the mean time here is my catalogue of errors!
