Cleaning option on the Form3 resin printer. Had a failed print that left some cured resin in the tank, tried this cleaning thing for the first time. Got most of it out by hand beforehand, was still cool to see though.
Question, the resin is a known carcinogen right?
So do you wear special gloves or what?

I must say the fact that they say the resin is super toxic and shouldn't be touched has put me off a lot

Most of what we use isn't that bad. From formlabs website:
Formlabs designs its standard resins to be as safe as or safer to handle than common household chemicals or adhesives. When measuring potential acute health effects of inhalation or ingestion, there are no known significant effects or critical hazards. Always consult the SDS for appropriate safety and handling of Formlabs materials.
And the toxicity details for the few other resins we use are similar. The printer is closed and in a separate room so not worried about fumes. I use protective eyewear whenever handling / cleaning parts and just use whatever regular TPE or nitrile etc. gloves when handling. Have never been too concerned with skin contact when it happens. The worst part sometimes is standing in front of a bucket of IPA cleaning a big part. /lung chunks

Busy building a second steam engine, and after the recent posts on printing on a mirror surface I though I'd post this to show printing a whole bunch of small parts in one go using a mirror as printing surface. No brim, hairspray, etc.

Any hardware shop or place that does window glass.

I just gave them the exact dimensions of my print bed, and they cut and beveled the edges. R50 or something for 2.

Bloody hell.

You have your retraction down pat - not seeing any wisping between the parts

For storing the filament I bought some cheap Tupperware-style plastic cake 'tins' at Pep. Think they were like R18 each or something. Standard 1kg filament rolls fit in them perfectly, like they was designed for it. Then I chuck in a packet or two of desiccant in each holder. Easier for me than having a big holder or bucket.

For one of my first designs I did, I remixed an existing design for a permanent solution for when I use the same colour for a long time (humidity is a bugger here at the coast), where I modified one of these cake tins. You can download and print from my Thingiverse page here: https://www.thingiverse.com/thing:4939764

Basically all you need in addition to the printed parts (listed on my Thingierse design) are a few bolts and nuts, 2 x 608ZZ bearings (skateboard bearings, very easy and cheap to source from almost any automotive parts store or from DaVinciLabs @ R17 each) and a PC4 M6 Bowden Connector (really cheap from places like DaVincilabs/DIYElectronics - same as used to connect your Bowden tubes to the extruder. This helps to let the filament out smoothly, but at the same time minimizes air going in). I've printed 4 of them, and plan to do 2 more. So then I can have six colours ready. No faffing about replacing rolls on the spool holder, and I can leave one colour in the printer for weeks with no issues even if I'm not printing. Works really, really well. The design should work with almost any similar round plastic holder.



For cleaning, I struggled using the included magnetic bed on my Ender 5 Pro. So I chucked it on advice from a different forum, and got myself 2 square pieces of normal 4mm mirror that I print directly on. Never looked back. No hairspray, nothing. Even did TPU on it over the weekend, and no adhesion issues. Clip it onto my printer bed with binder clips, so removes easily (just make sure the clips don't run into any printer parts when printing - I put the clips in the wrong place last weekend and managed to break my BL Touch mount off....).

Place the mirror with complete print to one side to allow it to cool, then the print comes off without any help (you can actually hear the PLA release with faint cracking sounds as it cools down). I then just clean my mirror with some hand sanitizer (medical grade, 90% isopropyl alcohol or just isopropyl alcohol - places like Mantech sell it in 1 litre bottles) and kitchen towel until I hear it squeaking under the towel. If I'm in a rush I just replace the glass bed immediately with the 2nd one I have waiting So I can start the next print on the fresh bed immediately, while I can allow the other print to cool and take my time to remove the print and clean the bed. Never used any soap and water until now.

Works for me. :)
Just wanted to say thank you for both of these tips - the Pep plastic cake tins and the mirror plate.

Did my first print on the mirror today with bulldog clips and it's absolutely brilliant - an absolute pleasure and the squares cost me R40 each (with smoothed edges and 'rounded' corners). Also didn't use anything on the mirror and the print went fine - the bottom of the print looks amazing too.

For the PLA on the spool I'm not going to go as fancy as you did - going to modify one of the containers to be able to slip over the reel arm, a clamp of sorts on the left and right and a hole for the filament to feed through - won't be as airtight as yours but a lot less work (I think).

No problem. Glad things are working for you. :)

For the storage I'm sure your plan would work up to a point, but the problem is humidity will get in through any holes. So it all depends on how fast you use up a roll. I only do printing as a hobby, so my reels can lay around for a while. Making the sealed, closed containers takes a while, but once they are done it is an absolute pleasure. Especially when printing in different colours, so you have to swap filaments regularly or when spending time between prints.

I am going to buy 2 or 3 more of those cake tins this week. They work really well for more permanent storage as well, as they stack up nicely.

You're convincing me to do it properly since it's a hobby for me too.

Where did you source all the non-printable parts from?

The screws/bolts and nuts I got from a local hardware shop. If you can only find larger ones, just print with 100% infill, and you can drill the holes slightly larger as you need. ;)

The bearings (608ZZ) I got from an autospares place in town, but the are common bearings used in many applications, like skateboards from what I understand. Most of the 3D printing supplies places like DIYElectronics and Davincilab have them as well. Quite cheap @ R15-R18 each. Also the Bowden connector and PTFE tube from them as well, also very cheap.

I've made 7 of those.
I printed one, worked well, then just printed 6 more (350mm build volume so was able to make it fit :ROFL:, took about a day but was worth it).
I should say I didn't bother 3d printing the 8mm dowel.
I just used threaded rod, I noticed the model you remixed the guy used rod also.

Anyway, I've got all my filament stored in those containers.
Just need something better to close off the filament hole for when it is stored (I did add some rubber seals to all the holes and just wrapped the lid with electrical tape, single turn).
I know it sounds paranoid but I left some ABS out for 3 months in Cape Town and it was completely unusable (live pretty much next to the ocean)
I had to put it in the oven at 70 degrees for 10 hours (first for 2 hours, better but still bad quality, then 4 hours, still some occasional artefacts, then another 4 and finally fixed).

New to all of this, son got an Ender 3 recently for his birthday happy with the setup and prints so far. He was adamant it should be in his room so I made a plan with an enclosure, the one from Creality wasn't available locally so substituted with a grow tent for half the price :

Mini LED security light from Builders at the top can slide forwards and backwards on the bar and extractor fan ( 12cm PC fan ) slots in nicely without any support in the exhaust hole.

Best place to buy a Creality 3 S1 in South Africa, preferably Cape Town?

Not necessary to be the cheapest place, rather most reliable where I can buy going forward.

Davinci Labs is in Cape Town, but they are sold out of the S1 now.


Ordered some parts and filament from them a few weeks back, good service.

Does the Ender 3 S1 have gantry levelling? (not to be confused with z-axis probe in the middle of the and bed levelling probes across the bed surface)
(ie. probe on the left, probe on the right, then adjust the two stepper motors to adjust the gantry to be level in relation to the bed?)

I'm curious if they have independent Z axis steppers or just steppers in parallel

Has anybody here printed and constructed one of these bad boys?

Where did you get hold of that nice grow tent? It looks great!
