What happened with this print? Never seen anything like it. It's incredibly soft and bendy, seems to have not adhered horizontally but did vertically, and has a fabric-like surface texture.
I've been 3d printing for about 4 years now. I've never encountered anything like this.
When the print finished, visually it looked perfect, but as soon as I picked it up it felt wrong. Squishy, and was easy to pull apart. It seems as though the vertical layers had weak adhesion, but the horizontal layers were completely seperate.
Weirder still is the texture. It's like a fabric mesh. Doesn't make me think clogged nozzle, since it's so perfect and uniform. Made me think maybe the extruder gear has a broken tooth so once a turn it doesn't advance as it should leaving holes, but the gear looks fine.
This is PLA, if was dried before use, I've used this roll before at this exact temperature and had prints come out normal.
The only slicer settings I used that were out of the norm were .25 as the layer height (rather than a single digit decimal) and 9 wall lines because that's how many it took to make it solid without infill. Could these settings be the culprit, or something else.
I examined the cross section of the layers in Cura's preview and everything looks totally normal there.
It's just an adaptor I made for a miter saw's dust port to fit a smaller vacuum hose.
Can anyone reccomend a good full face respirator that you can say from experience is compatible with a beard and eyeglasses that won't break the bank? (Canada)
I have a few respirators from the hardware store but they're not great at sealing over a beard and my glasses don't sit right while wearing them.
Obviously this is a common problem.
I'm thinking one of the full face shield respirators is what I need. I can find plenty on Amazon, but they jump from $30 junk right up to $300 professional ones without really anything between. I am just a hobbiest so I don't need one that can take career woodworker level abuse, just something that will keep the dust out properly as I am extremely sensitive to it.
Any reccomended ones you've actually tested if you have a beard and wear eyeglasses?
I asked the nurse to give the injured patient some painkiller pills before briefly leaving the room only to hear a bloodcurdling scream and a loud thud.
When I went to check what was going on I found the patient lying dead on the floor and the nurse in shock, unaware she was actually holding a bottle of Painful Killer pills.
[AUG26] I had always respected her independent nature despite her disability, and when she brought my patient in for the last time and requested to administer his final treatment herself, I had to make an exception to the rule.
I held the guide dog's frail body on my lap and placed the syringe in her shaking hands, only to feel a sharp pain in my leg and realize this may have been a mistake as the world began to fade around me.
Update: The Change Cage, AKA Picnic! At The Disco (rice).
I posted a little while back about using my compost bin to clean rabbit heads. This is an update. It's working *extremely* well.
The rabbit organs in the bottom of the bin attracted way more flies and the heads I had in the cage were mostly a little pile of goo and visibly picked clean bones in the bottom of the cage. More rabbits were processed since and 6 more heads were added on top of the previous ones in the cage (which had gone down to about 1/3 of their original volume in about a week)
The extra stuff in the bin and the existing disco rice 🪩 🍚 in the cage greatly sped up the process. This picture was taken just 3 days after the new batch of heads was added. What took about a week the first go around took under half of that this time. The teeth are still intact too, and with rabbit heads I've never had them stay in place once the flesh is gone.
I really think this might be a truly great method. I'm going to leave them in the cage until the maggots are all gone, because I suspect any still being present is a sign there must be some tissue left somewhere for them to eat, but the numbers are getting low so I think it's almost there already.
I did almost zero pre-cleaning of the heads. Just cut the ears off and tossed them in with the fur still on and everything.
If i wanted to position and preserve a dead spider, how would I go about it?
I've been making stuff out of resin lately and had a cool idea. I find a lot of dead spiders in my workshop, sometimes they are still pretty fresh. There's just a ton of spiders in here in genral which is why.
They curl up when they die, so how would I go about uncurling them and having them stay in position? Also preserving them so they don't decompose inside the resin?
I'm a noob trying to make 2 part silicone molds, but they're curing into a solid block when I pour the second half. Help?
I am using a mold release spray that had good reviews and says it's for silicone. I brushed it on and let it fully dry before pouring the second layer as the instructions indicate. They bonded together fully. There is no getting it apart without ripping/cutting it.
I've even tried pulling it apart with pliers along where the seam should be to see if the bond had a weak spot and would split where it needs to. It does not.
I tried again with a very thick layer of mold release spray that took several hours to dry under a fan to see if that helped. It did dry to a chalky white layer. But once I poured the second silicone layer, same result.
The mold release spray does however work well on the plastic container I poured it in and the objects I am casting, it just won't prevent silicone from bonding to itself.
Is there something else I could be using for this that would be better?
TIL if you pull brims off while the plate is still fully hot you get flowers.
This was accidental, but could definitely be dialed in if you wanted to make these on purpose. Just make a vertical stem and print it with a custom extra extra large brim, maybe heat the plate up above printing temp and pull straight up.
Figured id share this discovery in case it's useful to anyone. These are easy to add pleats to with a lighter too.
I think I've just discovered the best bone cleaning life hack ever. (NSFW just because the picture is gross)
The green bin (yard waste, food scraps, and other compostables) is always full of maggots this time of year. That's just a fact of summer.
They're so ravenous and active that I haven't actually had to put it out on bin day for several months becuase despite dumping kitchen scraps in daily, the level of stuff in the bottom never seems to increase because they eat it all, turn into flies, and leave.
Anyway I decided to harness the power of the disco rice and see what they could really do. Processed several rabbits yesterday and wanted to clean the skulls.
I took an old plastic container, drilled a bunch of holes in the bottom, attached a wire cage around it so it would hold more and have more entry points for flies, and hung it from a rope inside the green bin.
They were just whole heads with zero pre-processing at all, fur still on and everything.
This is 24 hours later. You can see a pretty much clean jawbone already at the top there.
Maybe dermested beetles are more effective, but these just show up in the summer for free and did all this in a day. This is incredibly exciting.
Although that paracord it's hanging by was white when I put it in...
Employer consistently denies one vacation day when requested in series, obviously to prevent staff from being able to travel. Is this illegal?
I'll start with two things;
I am in a union, and the union says it's allowed.
It hasn't happened to me personally yet, but it happens so often they call it the [company name] trap. It half rhymes, but I won't dox myself.
Whenever someone at my company requests to use vacation time they insist they put the full span they want "in case of schedule changes". Our schedules are very rigid and don't change with the exception of Christmas time when we're supposedly randomly selected to work it or not. It's definitely not random but seems to be loosely based on seniority, or maybe just favoritism.
Anyway, it's shift work, it's mostly 12 hour shifts, so no one is working 5 days a week becuase the max hours on a position is 40, but it's done by pay period, might be 48 hours one week, 32 the next.
So when someone puts in for a full week vacation or more at a time (3-4 shifts) they always reject one day right in the middle. This means any plans of traveling for that time are pretty much impossible. No one working for this company is able to leave the province ever for the most part. One person did for a couple of weeks while on temporary disability after a major medical issue, but that's the only time I know of.
Approved vacation days can't be taken back either, you put in, get what you get. However this doesn't seem to apply to supervisors, mine travels internationally several times a year no problem.
The reason for this at least seems to be for filling shifts. This company has no problem calling staff on vacation and asking them to take extra shifts on those days. They still get vacation pay if they work that day, but they give the pay for that day as banked comp (basically PTO that doesn't expire).
I and everyone else suspect they intentionally ruin any vacation plans to heavily encourage people to work on their booked vacation days when they're short, which is always.
Is that legal?
What is the best way to accurately measure extremely small amounts of resin?
I have a thick resin for coating 3d prints that was extremely expensive for small bottles, but is used in very small amounts.
It's a 2:1 mix ratio. I realize the more you're making the higher the margin of error is, but I only need maybe 2-4ml mixed at a time. When I've used it so far I'm using syringes for it, but I need to use about 12ml total volume of both to actually get a fairly accurate measurement, and a lot goes to waste.
It's used to just brush on the top of the surface as thin as possible to get a light coat.
Smaller syringes don't work, since it's too thick and traps a lot of bubbles if the container is too narrow like an extremely small syringe is.
Any ideas? It needs to be super accurate at these tiny measurements. I thought of using a set of teaspoons, but I worry what's left behind coating the spoon would be enough to throw off the measurement even.
I'm stuck being useless on my wife's schedule, how do I break out?
I have no idea if this is even an ADHD thing or not, but I really suspect it might be.
I've ended up stuck in a job where I work very much opposite schedule to my wife.
I do shift work and usually do 7-7 shifts, could be days or overnights. Either am-pm, or pm-am. Sometimes it's shorter shifts like 7a-3p or 3p-11p. It's all over the place.
My wife does remote work in a different time zone and works 12p-8p. It's 9-5 in the native time zone.
Due to my 12 hour shifts I get 3 days off a week always weekdays, she's off weekends only. Obviously this makes it inherently tough to have a relationship at all.
But also the one part I can control I am bad at and I struggle with it. On days I'm off before she starts work I am useless. We both have chores we've divided up and agreed on and our own personal projects we work on.
She goes before she starts work to do her chores and personal projects and I just... Don't. I do get all my stuff done by the end of the day usually but I waste the mornings.
My shift work is about 80% 7am shifts and 20% overnight shifts starting at 7pm switching at random. I default hard toward the 7am shifts because they're more common. My natural wakeup time is about 5am no matter how little I've slept. My wife gets up anywhere from 7am-10am, usually in the middle of that range.
Here's my problem. There's a few first thing in the morning things I always take care of; feed the livestock, shit the dogs, make the coffee and pack her a thermos. Then I just kinda disassociate and do absolutely nothing until noon when she starts work. She does a bunch of stuff before work, but I just kinda have zero motivation. Then when she starts work my brain kicks into work mode too and I go out and do all the stuff I need to by myself.
We're not working together on anything. She's doing a desk job in her office, I am looking after a mini-farm and doing chores related to that, house and vehicle maintainence, prototyping/3d printing stuff for hobby projects, building stuff, learning to play music is my new thing, etc.
But I cannot start until she goes to work. I don't know why. It's not something I can see to power through, it's like hitting a solid wall. I spend all that time sitting and scrolling and trying to convince myself to move and I just can't. Doesn't matter if we're in the same room or not, of of she's doing chores or projects or gone up to her office early to play computer games. I am somehow tied to her work schedule and have no idea why.
What is wrong with me and how do I fix it? Recently started on medication for ADHD and while I think I finally found one that's made me less likely to wonder if I have dementia, none I've tried have touched this issue.
First time working with resin, it's not hardening. What am I doing wrong?
de-moulded this I think Thursday and it's sat out since.
It doesn't seem to want to fully cure and I'm not sure why. The type of resin I am using is a two part so it should sure just fine.
I digitally designed and 3d printed the original item I wanted to cast in resin, made a silicone mold of it, used mold release spray that says its for resin, and mixed the two parts at a 1:1 measured ratio as it said.
My resin isn't setting up fully. It's like a semi-soft rubber, very malleable at this point after sitting out for 4 days. It was poured Wednesday morning, de-moulded Thursday afternoon and was still the exact same softness it is today.
What am I missing here? I want it as tough and hard as possible, is there anything I need to do in order to get it to set up? I'm not upset if this batch isn't salvageable it was just a test, but how do I avoid this in the future?
Included pictures of everything I used in case that's the issue.
This spray primer wanted to be different with the cap and it becomes even harder to remove when you've followed directions.
Vacuum chamber for epoxy resin?
I got some epoxy resin and I have some ideas for it. I've never used it before.
My understanding is that it's a good idea to have a vacuum chamber with it to force any air bubbles out if you want it perfectly clear and as strong as possible.
So my idea is to make a hollow wooden skeleton box for it, with walls made of plexiglass. I'll seal the corners with silicone caulk and a layer of sheathing tape on the outside for extra seal.
I was thinking one end would be open and have weather stripping around the edge and I'd glue the last plexiglass panel to a block of wood to make it rigid enough to secure with a clamp. I'm hoping this will be vacuum tight.
Anyway the issue now is what so I use for a vacuum pump? I'm not doing anything huge or at production scale, so cheaper is better.
I was considering using a hand pump for water that I have that is essentially a check valve on a rod in a tube that creates suction kind of like a giant syringe. Would something like that work, or is there a better option?
Caught my dog sniffing this (he didn't try to eat it). They're growing all over their pooping area. Just wondering if this is anything potentially hazardous or not.
My dogs probably wouldn't eat a mushroom on purpose, but they do enjoy ripping out tufts of grass with their teeth and having these in the area they often do that in makes me a bit concerned they might accidentally eat one.
Is this anything toxic?
Nova Scotia, Canada growing in grass. No trees or bark mulch nearby.
If I need a cheap tool: King Canada, Mastercraft, or WEN?
King Canada being a general Canadian budget tool brand, Mastercraft is Canadian Tire's store brand, and WEN is a (fairly well reviewed) Chinese brand off Amazon.
If you have experience with these brands, any of these stand out as a real winner despite their similar price point?
Looking to get a bench grinder that can take polishing wheels.
Employer is testing a new payroll system. They're going to deposit a dollar into my account and want me to drive into town and reimburse their dollar in cash and sign a sheet to say I got it and insist it's the same day.
I don't want to if I'm off that day. I commute a half hour each way and would have to go to the bank. Could they legally fire me or charge me with theft if I just keep their dollar?
Hopefully this is the correct place to ask a question about airflow dynamics.
My house has a sunporch that gets extremely hot from the greenhouse effect, and heats up the whole house from there. The door that closes it off doesn't really seal well.
There are only two small windows in the room that open, and one door that leads outside. I just fixed the screen door for the outside so I can leave the door open in this room to air it out.
I am trying to figure out what the best place to put a fan would be in this room to air it out and reduce the temperature.
The room is approximately 6' wide, 28' long.
The two windows that open (marked X) are about 9' away from each other and only open by 1x2' and 2x2' from left to right. Door is a full size screen door and is in the opposite corner marked Y here, the airflow from it should be comparable to just a fully open doorway.
Where should the fan go?
