i did keychains..

Aaron Strome nice.

I would interested in the stl for these

Ernest Sandridge Ill I saw Aaron's post and his keychains roll. Looked on thingiverse and didn't see an stl so I made these in fusion 360. I'm by no means an expert in Fusion 360 but this was a pretty simple design. A couple of circles and a couple of tangential lines, then extrude and there's a toilet paper roll.

this is the one i ended up making in the end the one i posted wouldn't print the extra paper area. but this one works.

Aaron Strome nice. Those look even better than mine. They have pleats and more texture and everything. Like I said I'm a complete new but 3D modeling so I thought I was doing pretty good to get a nice looking roll as I did haha

you did a great job. i'm still trying to learn fusion 360. i find myself spending so much time fixing models i find online i really want to learn to make them.

Aaron Strome ahh. Ya mine got a little weird at the start of the extra bit but it started after a few layers. it just kind of adds a bit of a torn corner look.

few of mine turn out like that too but thought it added to it..

Ya exactly

Not the worst idea out there. It's still an ethanol base. Depending on if there's any additives, it may or may not cause damage to the print. Best to test first, but several others have already tried this.

I switched to methylated spirits and mean green. Wash in one, rinse in the other.

Grab denatured alcohol from home depot or lowes ? its works great!

On my way! To the home Dope-O.

Says your in Sac, no denatured alcohol for you! You can thank CARB for removing it from our stores.

They had Mineral Spirits. Seems to work fine.

Metho works a treat been using it for a week

Makes me think of the tears you can get from overexposure, but that usually takes a lot to get

Which resin, I had this happen with a batch and I never could work out why

Also what model is this?

I also have this kind of problem

It it's just random extra tiny layers, that is frame shearing. You will have to update your firmware to get rid of that.

If layers not quite sticking to each other (delamination), that's a sign of under exposure.

What are your settings ? Especially the Layer settings

I had this happen when I left a part that was washed but not post cured in an area with ambient daylight for several days.

The wierd thing is the next batch was fine. Maybe I forgot them lying in indirect sun light too long or something

Aaron Shrive from Reptilian Overlords patreon

Emil Gudmundsson will be going to check them out!

Actually think it looks cool on the armour bits ??‍♂️

Screen flicker it could be failing

Stir your resin.

Which firmware?

Have you run a resin calibration test (assuming you have a classic Photon) or the RERF test (if it's a Fauxton) to find out the correct exposure time?

I haven't, but I've been printing nothing but successful prints with the same exposure settings for months, then I started noticing stuff stuck to the FEP vat that progressively got worse and worse until it was unusable. I figured it was probably because I had been using the same FEP liner for about 4 months straight, and it was starting to get cloudy, so I switched it out, but the exact same problem persists.

I should also mention the shape is the exact same size, approximately the same shape as the inner square of the UV Test. This occurs even if I'm printing a small item, about the size of a quarter, right in the middle of the build plate.

Each bottle is different. Ambient temperature affects exposure time as well. Your LED also gradually becomes weaker. You've been lucky so far. Go back to the basics: calibration test first.

Are you running the original Firmware on the printer, if so it could be frame shearing.

I updated it shortly after I got the machine... about June/July of last year, because I was having some issues where it would just die in the middle of a print. Haven't had a single problem (that wasn't operator error) in the 8 months or so since.

Given how deep the shit is with shortages that the CDC is even asking frontliners to make do with bandanas (!), I say carry on printing. Anything is better than nothing.

Biocombatibilty. Photopolymers once fully cured are just plastics. No worries about leaching we're not talking about stic king it in your mouth or implants.

Rigidity and sealing. Choice of resin is key. Flex resin, etc. are available.

Filtration. Again, anything is better than nothing. Because, viral load.

Finally, wearing a mask is not all about protecting yourself. Don't go getting a false sense of security with one. All it does is reduce the risk for you and (if you're asymptomatic) everyone around you. The more people that wear a mask, the better.

CDC is telling HCP that a bandana is a last resort in the absence of PPE. What we are printing is the same, except you are proposing to use photopolymers which contain unknown monomers.

The material on your link seems ok at in least short term. For sure if things got desperate I'd wear whatever i could get my hands on.

Sure it's not on your mouth but it is in the wet air path which is subject to tighter regulations than just skin contact as it reaches mucosal membranes. You shouldn't fit these to someone effected by the virus in case it was an irritant and worsened the pneumonia

Sen Kun https://www.researchgate.net/....../258525804_Testing......

Absolutely.

" The median-fit factor of the homemade masks was one-half that of the surgical masks. Both masks significantly reduced the number of microorganisms expelled by volunteers.. "

Homemade masks as an alternative to commercial face masks. Better than nothing. This is the situation no?

Sen Kun that a sewing machine and a tshirt is better option? Yes.

nextdent ortho clear resin is biocompatible it is for dental splints and retainers

The main three routes of entry for viruses into the human body are the mouth, nose and EYES.

Not enough exposure time possibly.

It's too big of a flat surface parallel to the base. When it lifts up the weight of the liquid resin is ripping it off the supports.

Angle it so the resin can drain off a slope.

Christopher Fugate I’ll give that a shot, thanks!

Had something like this happen to me earlier and it was because I had hollowed my model and my drainage holes where not big enough and I got to much suction. I would check for any cuping in your slice. Also you might want to lean back your model and use prusa slicer to create your supports.

Jack Burton Whenever possible, do not have large flat surfaces pointing towards the print bed. I'm honestly impressed it printed as well as it did!

Put in stronger supports, medium or heavy..

Daniel Kottmair is there a guideline on when to use light, medium, and strong supports?

Christopher Fugate thanks! Restarted the print and it’s looking better so far. Will report back with findings ?

Jack Burton No. Common sense and experience I guess, i learned also the little I know through trial & error, and I'm far from done! ;-)

Heavy when they need to carry A LOT of load (or strong angular forces, don't forget about those!), I also like to support the corners of slabs with a medium..

Tilting the model was the answer, thank you! It seems like I should be able to print the model way bigger than Chitubox lets me. Do I need to adjust the build volume for the Photon S or is the LCD smaller than the build plate?

Resin, in my experience, isn’t super great for that sort of precision.

Have you try to print it flat directly on the plate ?

No, it would be pointlessly slow to do one at a time that way

you have to add supports. because the first print bottom exposure time is higger so the size would be tiny

like this?

Tom Inglis look ok to me

Lucas Parard will try tomorrow, thanks!

Tom Inglis what brand of resin are you using ?

Lucas Parard tech outlet grey

make a good master by hand, make a silicone mold, cast 20...

I love my photon and sometimes it just makes sense to work with other tools

Bastiaan Droned if I can get this right I can print off 15 or so at a time

Resin print shrink during curing.

pour out the mixture, rub it down with clean alcohol, let it air dry, then throw it in the dishwasher to be safe. As long as it didn't cure to the glass you should be ok.

Glass? It'll be fine

I'd dump it out, wipe as best you can, and hit it with acetone to dissolve anything left.
