Alien Pulse rifle , first major print from the Bambu H2S really pleased with the quality cant really see any layer lines in most parts. Just need to read the assembly instructions now as so many parts

I recall watching a program, something like 24hours in police custody or the likes and they’d been printing some firearms. My memory is a bit foggy but I think they seized the printer and tried to forensically interrogate it to see if it had actually printed the files they found on the computer. They then printed the files and an expert tested the printed weapon to see if it could be used in anger. Can’t remember the outcome other than them stating it was very dangerous being that it could self destruct with a live round being fired from it, again can’t remember what happened to the suspect.

Anybody with a lathe and a mill could quite easily if dangerously make a working firearm , this is for display purposes only but I get your point. I often go to Comicon's with my son and am suprised at the number of people walking around in costume with real looking prop weapons

I seem to recall reading that someone made a 3D gun print that allowed a barrel & chamber to be fitted as well as a steel firing pin for a repeating pistol . I understand that sending files of such things over the internet can quite easily be tracked and investigated.

It would be really easy to design such a thing but stupid to share such files as there are people regularly checking for such things and hopefully would get more than just a caution for doing such a thing

There seems to be a bill a senator is trying to get made.law in the USA to make 3D printer report you for trying to print firearms, I don't see it going anywhere but it's got a few chatting about it on YouTube

Perfectly legal to sell 3d printed parts in USA

When I was a kid we all ran around the streets with toy guns and rifles etc never once had someone complain , how times have changed . Maybe for the better not one of us became criminals or it affected us in any way

back on topic next print will be a vase i need to justify to the boss its not just for printing silly stuff like film props

Printed a couple of remote control caddies downloaded from Printables.



That's the one I've used for the remotes, obviously.

The other one, I thought I could find better use for.



Perfect for the task.

Printed with the Sunlu matte Mint Green filament.

I have an a1mini for small bits in pla and have recently added a qidi q1 to the workshop, that pretty much exclusively runs engineering filament.

How are you finding the qidi printer @HughF

I found a Thrud figure online, the other week. Printed with the Mars.

I think (it's still up in the air) I might need to print a bunch of pieces for a flexible conveyor belt, needs to be grippy so I'm thinking ABS for the bottom then a layer of TPU on the tip

can print upside down to TPU first then ABS ontop (might need to work out the details later)

but... anyone using tup and other materials... do they stock together ok

or am I better printing separately then glue?


Can't find anything available for sale to do what I want to do

You'll probably need to design some sort of interlocking mechanical joint between the two filaments - some sort of pin or 'rivet' printed in place

Iirc, TPU doesn't bond well with any other filament - it is *very* good at bonding to itself* so should be used as the "male" part of the interlock.


* I printed a replacement castor wheel at 100% infill, with tree supports.

I could *not* remove the supports.
the dog had been using it as a chew toy for the last six months, and they are *still* attached.

print in place with multi material printer, or print separately and then push/glue together after?

I've no experience with TPU... a bit worried about different printing/bed temps of the different materials?

Happy enough to buy a new printer to print these with, cost of printer is tiny compared to getting someone in do custom build something for me

 

[daedalusminos]

TPU isn't very grippy and ABS isn't very wear resistant.

If you need something more like nylon then that dictate choice of printer.

 

[knighty]

ok... what is grippy?


I thought ABS would work, almost everything I print is ABS, can swap to nylon instead.. I have a roll somewhere and was half thinking of trying it for this anyway
