I’d suggest sanding with coarse to medium sand paper, then filler primer. The sanding will help with primer adhesion and reduce the number of extra coats.

This is 'murica. we use Webster’s here.

(sorry. couldn’t resist. you are correct. this isn’t a solution.)

not really. Well let me put it this way. The firearms that are entirely 3d printed are basically one-shot weapons.

the firearms that are single-printed components (or maybe more,) aren’t printing components that are part of the firing mechanism. for example, the DefCad team, they’re printing lower receiver for an AR. All the lower receiver does is holds the magazine in place for feeding into the chamber. For some technically obscure reason, it’s the part that is defined as “the” firearm for the purposes of registration.

the reason most ghost guns aren’t actually being printed is because there’s easier ways to get better firearms. Like driving to a state that allows the gunshow loophole and buying them cheap and flipping them in NY or whatever. printed ghost guns are… relatively uncommon, overall.

an Ender 3’s print quality is too low to reliably handle any of the critical components, even for one or two uses. something like the defcad AR lower receiver (which is for some odd reason designated as “the firearm” under ATF regulations…) can absolutely be printed, but not reliably by an ender 3- at least not a stock ender 3. (the defcad team was using resin printers for the dimensional accuracy.)

in any case, you can go to any big box hardware store, drop around 30 bucks in plumbing parts and some quality time with a dremel will produce a fully automatic firearm. should we now regulate plumbing hardware?

“Three-dimensionally printed firearms, a type of untraceable ghost gun, can be built by anyone using a $150 three-dimensional printer,” Rajkumar wrote in a memorandum explaining the bill. “This bill will require a background check so that three-dimensional printed firearms do not get in the wrong hands.”

… No way an ender 3 is going to produce something that doesn’t blow up in your hand.

so. i suggest people get that 150 dollar lol-printer. Should take care of itself.

Well… you haven’t met Kyle. When he lets one rip… everybody in the room teleports outta there. dude should ask his doctor about lactose intolerance…

You called?

next, you’ll tell people the door close button in elevators doesn’t actually work.

macgyver always carried a few slices… in case he needed an industrial sealant…

But we like the dark.
Darkness, for dark deeds.

you have to understand, my dad’s a unix sysops guy. it was quite a lot of spare parts… (mostly machines older than my 486, which was also hand-me-down.)

Also, that imagery might be closer to reality…foam sword and all.

Two slices, you say?

Hehe, that might actually have been more of the Uncle’s influence.

He’s the one that started me on the science fiction addiction- when I got into his (then-complete) collection on VHS. I found them and started. Binge watching them. Got to Trouble With tribbles when I was found out- and then it was my Uncle who was like “oh! That’s my favorite. Rewind it while I go make popcorn!”

well, if it’s your personal mac and you’ll be taking it with you, it’s difficult to see import taxes being a necessary thing.

It’s more the… if a group of people can’t get “good” hardware because of export controls … legally… some might take a shine to yours.

my first beowolf cluster, I built because I wanted to improve my pentium 486’s chances at doing well in some random FOSS benchmark (PiMark? it calculated pi… and you could ‘donate’ cpu runtime to help calculate more digits of pi.) It was cobbled out of my dad’s spare part’s rack.
Should have seen my dad’s face when he realied why i built the beowolf… “You mean… you did this. FOR PI??”(“Okay, that’s actually cool.”)

Also, you gotta be careful with macproducts some places.
Especially if they have export controls (Doubt turkey does, being nato,).

Retirement.
life of leisure.

Sure I’ll probably still find something useful to do. maybe even productive. But. It’ll be my choice and not a job.

First video game I remember playing? Short Order on NES (with the pad.) That was followed shortly by monopoly- also NES.

First game I beat? was dad’s copy of Zelda (NES,) Which… I wasn’t supposed to be playing. I got caught when I saw my dad was struggling with the water temple.
“Dad…dad DAD. you go here. get that. Do this. And then do this that and this.”
“Oh. Cool. wait. how do you know this?”
“Oh i beat it last week.”
<awkward pause>
“you better pay attention. that’s the boss.”
“We’re not telling mom about this.”

That’s nice print!

it’s better to hobby with the kids, than not. When I first got into 3d printing…. My dad had one of those freebie inkjet printers; you know the ones… “free with computer,” but then the inkjet cartridges cost more than the PC did?

It ran out of ink, he was grumbly about it. So I asked if imcould have it. A few months later on was talking about printing stuff on it… I think he wanted to print out taxes. Yeah. “It doesn’t print those kinds of things any more…”

This was late 90’s? I read an article in … maybe it was popular mechanics or something like that… and got obsessed) that was a hideous printer.

You know… I think you just gave them an idea for merchandising…
