Wow, wow wow! I’ll set it up Tuesday when I get back to Lundun
Can we clear out the former woodworking shop so we can place new printer

Cool! Need to setup extraction too, will see what we can do on that this week!
I will be down Tuesday evening as we are dropping off the flooring. Will be happy to help set up/move stuff from the current setup.
Nice one! Give it a go!
Woohoo, SLA printer is setup and working!
Please leave the IPA alcohol and tissue paper by the printer all the time, in case it’s needed for accidental spills! (If there’s a special place for those please let me know, but there should always be some supplies by the printer.)
I asked everyone that was staying late in the shop if they were willing to sniff some resin so I could do a test print. I expect the passive ventilation to completely clear any remaining volatiles by morning. The printer and cure station covers should contain any further emissions, but give me a shout if you notice any smells. That said I cleaned up everything and I’ll wait for the fume hood until further prints. Everything in the garbage box is cured and safe to throw as general waste.
I’ll work on the induction until the fume hood is put up. Though please let me know when we do the hood so I can help

IPA should be in Coshh cabinet.

Where is that? I was looking for an IPA bottle I left by the FDM printers that went astray, but couldn’t find it.
Also, we should probably discuss how to handle the cure station IPA bucket. It has a sealable cap. I think it should stay in the cure station because of the resin contamination, and because there’s a process to recycle most of the IPA. And more importantly, a process to discard the dirty IPA safely, which will be covered by the printer induction.
I’ll bring another litre of IPA either today or tomorrow.
The 1 litre bottles should be living in the COSSH. A smaller quantity (<250ml) would be cool on the table next to the printer, re accidental spills etc. We should get some HDPE wide neck storage bottles though.
The two cabinets are located in the old woodshop on the floor when you come in on the left (last time I was in the space). Only temporary, because they used to be in the old snug and we’re looking for a new home for them.

I know you can get water-washable resins - are they any good? Would they be a better bet than using IPA to wash everything?
Any thoughts on where these should go given the new layout?
Snug 1 next to the spray booth seems reasonable.

Sounds good! Thx
Water washable resins are not environmentally friendly unfortunately, we still need to process the dirty water before disposing. I decided not to include them because there are a few more minor disadvantages. For one it’s is a worse cleaning solution; on the washer manual it specifies 15min for water and just 3 minutes for IPA bath.
The advantage of water-washable resin is that it can be used in an ultrasonic cleaner and it leaves no smell or vapor. It is very important that the residual water is not thrown in the drain because it contains resin. Water washable resin often contains raw materials that can be harmful to aquatic life. Therefore the washing method would be similar to using a resin cleaner.
Finally we can mix most resins of the same “wash type”, and that will allow us to have a bottle of arbitrarily coloured resin that everyone can use. Mixing tough resins and basic is fine and you get halfway properties for the final result.

Fair enough!
We are beginning to clear the woodshop out tonight!, I hope this gorilla project is on schedule, it will need to be gone from the space by Sat. March 18 We are moving textiles and 3D printing in there and it has a knock on effect for the electronics area and classroom setup in the clean room.
Thanks!

Also I noticed a lot of more stuff there, we should find a safer place for the laptops as well.
Which reminds me, we should start to have a plan for electronics waste

Yea sounds good - We will have tech/space storage shelves in Snug 1 for things like the laptops…
Uh, can’t help tonight, unfortunately came down with a flu.
No worries, thanks for the note!
BTW I didn’t know where to throw the shipping boxes. But the 2 big boxes underneath the table filled with styrofoam are ready to be binned.
Don’t bin the empty IPA bottles though, they’re in a labeled box in the back. I can handle it in a couple of days if that’s too confusing
