I make these 3D printed pens on an FDM printer. I wonder if the cured resin would agitate the skin with prolonged use if i printed them on a resin printer. Thoughts
我在fdm印表機上做了這些3 d列印筆. 我想知道, 如果我把它們印在樹脂印表機上, 治癒的樹脂會不會長期使用激起面板. 思念

From what I understand cured resin is mostly safe to handle in non food related activities.

Fully cured resin should not irritate skin.

Are you putting them on the lathe and putting a finish on them? That would put a barrier between the skin. A lot of exotic African & South American woods that I've made pens from irritate skin as well.

No lathe. The pen bodies would be purely 3D printed. Thanks for the note though

Resin out preforms FDM in all categories except price.

Certain items can be printed faster by FDM machines if layer thickness is not critical.

Both technologies have strengths and weaknesses. I use both all the time. FDM is generally much better for bigger stuff than resin. Case in point, you can use FDM to print something as big as a car. I can't imagine that being realistic with resin, even if resin was free and you could get it in 50 gallon drums, lol

LIKE LAST TIME.... this is a false statement. It is mechanically impossible.
Have you ever been a used car salesmen?

like I said it’s not cheaper. But it’s 10x faster, stronger and detail isn’t even comparable.
They make huge resin printers. I saw one make a boat haul. That said the machine was $20M.
Not cheaper, but better.

You flat out called me a liar the last time. A Used Car salesman and old man this time. Why do you think you can get away with this?

last time sure. This time no. I’m old too, so that doesn’t count, plus it was a joke. The other thing was a question.
Lighten up a little. The world is not out to get you.

I have seen a BAAM in person. I have never heard of a resin printer that big. It doesn't seem worthwhile to make a resin printer that big. My point is that it's not better at that scale, regardless of price. Just because you can, doesn't mean you should, lol.

resin prints way faster, if your printing minis u can print 10 vs 1 on fdm, if you are printing buildings, resin is still faster as it does the whole layer at the same time. I started with resin and just got an fdm for terrain stuff, resin is so much better

Personal use, or selling? If the latter, you might want to be a bit more cautious, 'just in case'.

Ask oneself is it safe to put in your mouth like say Dental applications or surgical apperatus & you may find the answer.

One small advantage of FDM over standard resin I've observed is distortion - FDM doesn't warp as readily as resin does while curing so if you need a high degree of accuracy of overall shape FDM may be best.
Saying that I expect there are resins out there that are designed to overcome this issue.
Still, not going back to FDM - resin is amazing.

Huge disagree and I've used both for many many years and worked in the sla field

There are plenty of resins you could use if you're really concerned about it. This is just an example, but pro black 10 resin from figure 4 is Biocompatible capable per ISO10993-5 and ISO10993-10, which means this:
ISO 10993-10:2013 Biological evaluat
ion of medical devices Part 10: Tests for irritation and skin sensitization
ISO 10993-5:2009 Biological evaluation of medical devices Part 5: Tests for in vitro cytotoxicity.
You wouldn't really need to go to these lengths though as people have said prior to this comment, fully cured resin should not irritate the skin. But this kind of resin would be safe if you're one of those people who bites things haha.

jjust make sure to leave it in the sun for a few days

basically leave it out until it doesn't smell funny

Resins become chemicaly inert once polymerised. Like the look of your pens by the way out of interest I turn pens from wood on my lathes occasionally

Thanks for the note. Those are 3D printed using a hemp based filament

Show me a resin comparable to ULTEM or PEEK

people like to put that in their mouths, (it’s a joke) there are no hemp based resins that I have ever heard of.

I’m not looking for a hemp based resin. Only stating that the pens shown in the post came from a hemp based filament

I've been wearing a printed resin ring as my wedding ring for the past 4 months. No issues.

it does after prolonged exposure. I printed a hollow 16mm ear tunnel last year, after three days it caused blistering and swelling inside my ear and I had to cut the earring out.
I also made a fidget ring for someone who experienced similar on their finger after a few days.
You won't have any nasty reaction to chemicals found in PETG/PLA/TPU from FDM, but you likely will with resin.

Anycubic grey resin, printed on a Photon. Cheaper than gold, and if I want a different design, no problem! The first one I made broke during our honeymoon. This ones been solid for 4 months now
