c4 can be made into a clay like consistency and printed into
cups, enclosures, and other solid objects.
keep a detonator embedded in the device and give it to
people or leave it whereever . print whatever shapes are
needed.
printing clay with extrusion .

C4 has always been my favorite Battleship opening move. |
|
| |
It won't retain its structural integrity for long ; the plasticizer will
degrade, and the object will have little or no mechanical strength. |
|
| |
You would be better casting or injection-moulding HMX or PETN,
but the result is brittle. Extruded PETN rod can probably be fed
through a 3D printer.That would be a useful way of custom-
manufacturing unique shaped charges, so [+]. |

How about putting this idea in Business:Advertising:Product Placement? |
|
| |
Possibly - but after all, at least it's not in ... oh, wait .... |
|
| |
"So who was that who they hauled away in the ambulance? " |
|
| |
"Our new printer technician. His coffee mug Exploded." |
|
| |
If this becomes popular, there would be a risk of everything exploding in a chain reaction. Like those Minecraft worlds made completely out of TNT. Fine until something blows up. |
|
| |
Yes, but the crystalline polynitrated aryls are not easy to initiate. They
burn well, and fast, even in the absence of oxygen - it's fun to light a
block of TNT, then drop it in water - but detonation doesn't just
happen. |
|
| |
So there's no deflagaration-to-detonation transition at all, or not with small samples? What if it's enclosed? |
|
| |
Anyhoo, you were commenting on a different idea a while back about machinable monocrystalline explosives. Are there useful geometries that 3d printing can achieve, that machining can't? Or is this more about doing it more cheaply? |
|
| |
...Or are you just in favour of making explosives a more ubiquitous commodity? |
|
| |
Even Home:Wall:Change or Home:Pest Control would be more appropriate. |
|
| |
Maybe you could employ Aardman Studios? |
|
| |
That could explain how they got to the moon so quickly. Does C4 taste anything like Wensleydale? |
|
| |
No, and consuming even a small amount of C4 will cause serious
illness or death. |
|
| |
// So there's no deflagaration-to-detonation transition at all, or not

|
| |
Not with small amounts - less than a kilo. Pressure and temperature
in an enclosure change the game. However, it's often the abrupt
failure of a pressure vessel that will produce a shock wave strong
enough to initiate adjacent material. |

More flexibly. The geometries tend to be fairly standard; it's the size.
3D printing on demand gets away from the "Small, Medium, Large"
limitations of repetetive casting, and the "one-size-fits-all" approach
so beloved of Quartermasters everywhere. |
|
| |
// ...Or are you just in favour of making explosives a more ubiquitous

|
| |
Whatever gave you that idea ? |
|
| |
//consuming even a small amount of C4 will cause

in it? |
|
| |
OK, a quick search shows that nothing in C4 is
particularly hazardous. |
|
| |
RDX (the fun part of C4) "has low to moderate
toxicity with a possible human carcinogen
classification". Frankly, that goes for a lot of what I
drink on a daily basis. |
|
| |
Incidentally, in [teslaberry] I think we may have
found
a Halfbaker who has learned to write but not to read. |
|
| |
If 8th claims to have constructed some monocrystalline rdx, send somebody else over with a video camera: I'm pretty sure fracture speed is in excess of detonation requirements. |
|
| |
Experiment: drop some HCl onto a bit of rdx, see if it outgasses or something. |

Yeah, funny how that seems to work. Brevity being the better part of wit, discretion is the better part of valor, and unresponsive to comments defines the aptitude. I guess that's one step up from a deletionist. |
