Stranger things figures from black V1 resin dated 2014 - results

[Peter_Peck]

I found 1 liter black V1 resin from 2014 which I have stored all the years between 17 and 25 degrees in a closed bottle.

Thought I give it a try for some Stranger Things figures and test if the resin will still print. Figures from Purakito can be found here - https://cults3d.com/en/3d-model/game/stranger-things-season-one-set-purakito

After shaking the bottle for quite some time over 2 days to achieve a good mix I was astounished that the resin looked good in the vat.

See for yourself how the prints, primed and non-prime and painted figures turned out. This has been my first paint job ever so please bear with me

I cut all supports with the flexible extension of the Dremel 4000 and a cutting disc. Sanding has been done with a smaller diamond tip in the flexible extension - in the case of Dustins figure I removed the support points from his face with the sandpaper accessory.

Very surprised that resin that old performed so well.

One hint I can offer is to use needle files vs sandpaper or Dremel.

You could easily get the remnants of the supports to be flush with your model using needle files. They, like anything else, are in the “you get what you pay for” category. A very good set of needle files is easily over $100 but you can get a decent set for far less. Check jewelry supply places on the Net. The various grades of “cut” (coarseness) can be confusing as different countries have use different designations for the degree of coarseness. https://www.kmstools.com/blog/hand-file-identification/ This is a decent primer on file lore.

The files will cut the support nubs only (if used properly) where sand paper conforms to the remaining bump and thus only smooths it vs removing it (as can be seen in your photos). I’m not criticizing but just trying to help with your next project to get the results you probably desire.

Keep printing and posting !

Nice!

I can attest the Black V2 resin (at least the cartridges I got) had really good shelf life, too. I miss that resin.

Thanks a lot for your report.

I do have an unopened 2013 vintage Formlabs Clear bottle in my resin cellar. When the time is right i’ll give it a try and report back.

LOL like a fine wine. I still have a 500mL Flex bottle, from the original formulation (before it was black, and before Elastic was a thing). Still printed last I tried it, but the prints degrade pretty quickly with too much compression or friction (in fairness I think that was always the case with the Flex v1 prints).

What does your shaker look like? You might get a laugh out of this.

Wow! Not bad for half-decade old materials.

Nice ideas for mixers
I only had my 2 arms to vigorously shake the resin bottle a couple of times over 2 days
