Hey nice video there :D I have few questions such as how do you discard the filter and at what frequency ? (After a number of batches ? Kilos of resins Cleaned ?) Do you turn the system as often as possible or when it's start to get clumpy ? Do you cure the filters so you can use these a little longer ? How do you dispose of those, since it's still hasardous material until it's not cured.

What about the resin building up on the inside of the tubing? I use a plate stirring unit, a glass beaker and a uv light. The side of the beaker gets covered with resin after just a few minutes of running the system. I then just use a filter cone to get rid of the cured resin. Plus I also have to clean the resin off the inside of the beaker using a paper towel and then some alcohol wipes.

I built this with the exact parts list and it ran great for several weeks. There was no sediment after washing several liters of parts though the IPA slowly darkened to the point that was difficult to see the bottom of the tub. Then the pump started to leak, slowly at first but became much worse over time. I t would suck air into the system when running and dribble IPA when shut off. I disassembled it and couldn’t find the problem so I reassembled it with silicone grease hoping it would fix the problem if only for a short time. However it was just as bad as previously. The only difference between the setup here and mine is that I mounted the pump upside down from the way he has it. Does anyone else have experience with running this setup for four or more months? Have you had any of these issues?

new info: the pumps have a safe run time, we found them listed about 5 minutes, 10 minutes cooldown. after running for an hour one day the pump started leaking. gaskets or something failed inside, and was a mess and needed a full replacement short of opening the pump. went a good year before it failed from that.

Hi Nick, I have been running this system now for a couple of weeks. So far it’s doing a great job cleaning the resin off of my prints. I’ve done about 3 liters or resin through it and there is still zero trace of resin in the IPA. However, I am running into an issue with my IPA getting super cloudy. I’m assuming it’s because I’m using Sunlu 14k dark grey resin, and maybe it has additives in it to print higher detail? I’ve noticed tiny white specs on my prints after I wash them, which I’m assuming is leftover pigment or something. I did some research and it looks like Prusa has made a specific cellulose membrane filter to clean up the leftover particles from the IPA that aren’t resin, so I was wondering if you have any ideas on how to filter out this extra stuff? I’ve tried a flocculant and that made my test IPA from my vat even cloudier, so I’m at a loss as to how to get rid of the extra stuff in the IPA. Any help would be greatly appreciated.

I’ve seen folks mention carbon filters, but I don’t know what is any different than the .5 micron filter you’ve already linked. Other than that I’ve tried setting it out in the sun, UV curing it with another lamp, etc, but there isn’t any resin cured after doing those things. The reactor coil seems to catch the actual resin, just not whatever the cloudy stuff is. I’m open to adding another filter or even replacing the ones I have now with different ones. Maybe I need an even finer micron filter with the 14k resin?

@@nicks-fix Mystery solved! You were right, it was a UV light curing issue. Even though I took out some of the IPA and let it sit in the sun to cure, it must have been just enough off the top of the IPA to not have much resin in it. So it made me think there was no resin in the IPA. I decided to go all out and set all of the IPA in the sun, and sure enough, almost solid white. So that meant my UV light wasn't curing anything at all. So I ran it through my system again and it appears that my UV light I used to replace my insufficient UV LED's wasn't actually hitting the coil, it was focused almost dead center of them, so it wasn't getting the UV light to expose the resin in the IPA. I've got a new set of UV LED's so I'll get that fixed soon, but now the IPA is crystal clear again. Lesson learned part 2.

It’ll take a good amount of time for the vinyl to degrade. You can easily upgrade to silicone lines for longer care free use. As for the resin sediment, I don’t recommend attempting to filter a fully saturated basin of ipa with this, as it’s not the intended use. It’s meant to filter out after each wash, not in a batch processing. In addition the pump is a diaphragm pump. By design a clogged intake line would have little to no effect on the pump, and definitely would not damage it.

How have the filters held up? I'm considering whether this is worth it for a small high-volume operation. I know they're consumable and will have to be replaced eventually but I'm wondering how many liters of resin you were able to get through before replacing the filters. It's not a cheap setup so I'm wondering where the tipping point is for it to be cheaper to just buy new methylated spirits lol. Also, any particular reason to go with a 12v pump over a 220v? Another question I have is about vinyl, I know in gloves we use nitrile because of the monomers seeping through, but is it because the rvinyl tubing is really thick that it's not an issue?

First thanks for the information. I have built this system and really look forward to a much better washing system. I have two issues (questions). First the filter size. I see that the Amazon listing shows 0.5 microns for the carbon filters. However I do not see that confirmed on the packaging. I suspect these are 5.0 micron filters. I compared to another purchased filter that was labeled 0.5 microns, and there was a huge difference in back pressure. The validated 0.5 micron filter caused much more back pressure compared to the listed filters.... the pump struggled to push the water through... got a few leaks too. So I switched back to the listed filters. Are we sure the 0.5 micron filter is the right filtration size? My IPA is looking very mirky without the 0.5 micron filter installed. I need to decide whether its worth it to try and get it to work. I am just looking for confirmation. The other issue/question is pump flow rate. Seems to me a much slower pump would be more ideal for the UV light to have more time to solidify the resin. I think the IPA is flowing threw the UV light too fast to actually cure. Anybody have recommendations on a slower or speed controllable pump?

I am still waiting for someone to start manufacturing ITO/FTO-coated heating screen protectors for efficient FEP heating. For example, KRALYN demonstrated it's use as heatbed for his FDM printer PositronV3, so it is definitely viable. Only thing you need is suitable ITO-coated glass, PSU and some kind of thermal feedback. Also, I am devising IPA filtration based on continual deposition of resin on a disposable surface. Imagine stairs on a slight slope covered with disposable non-woven fabric, complemented with overhead UV floodlight and peristaltic pump. UV light will cure resin only on the fabric, and peristaltic pump will cycle the IPA over the stairs over and over until it is clean or until the fabric is all saturated. It would be all sized up for ultra-cheap 10.6l Ikea 365+ container. Originally I planned to build it in the container's lid, but it would provide better access to the filtration fabric if it were on a standalone frame, only encased in the container. Replacing even hundred of sheets of non-woven fabric is still cheaper then replacing one proper filter, it is clog-proof because if the fabric is saturated, the IPA sipmply spills over to the next stair and eventually back to the bottm of the container. I expect to have it built by the end of the march. What do you think?
