Oasis 3DP questions
Posted: Wed Oct 24, 2018 5:03 pm
It is cool that there is an open source binder jetting printer.
I have a few questions:
1) Has anyone printed using metal powder?
2) If no one has printed using metal powder, do we know if the binder being used will work with metal powder?
3) How fine does the powder need to be? The sandblasting industry is a source of inexpensive metal powders ($1-$10/lb metal sandblasting powders versus $100-$200/lb conventional mtal 3D printing powders), but the sandblasting metal powders aren't as fine.
4) How much binder fluid is required to make a 1 cm^3 cube? I'm trying to get an idea as to the cost of this approach. The ZD-16 binder is around $300/gallon plus around $50 shipping+handling plus taxes/brokerage/etc.
Has anyone else starting trying to make one of these? I took a brief look at the bill of materials, and a lot of what is required can be ordered from banggood.com. If anyone buys from them based on my recommendation, you should know that I have ordered a lot from them, and that there is something wrong with their orders around 5% of the time. They've always fixed the problem, but I needed to jump through their hoops (youtube video, photos of the product SKU (keep your packaging!), etc.etc.etc.)
Some of timing belts are closed loop. How hard will it be to change the design to use slightly larger closed loop timing belts, in case we cannot get the exact sizes mentioned in the bill of materials?
Approximately how much did it cost to make the Oasis 3DP?
Thanks,
Fred
