polycaprolactone

In the present article, the problem is that dissolvable sutures are made out of biodegradable polycaprolactone, and there's a Pseudomonas biofilm that can grow on polycaprolactone, so it's an infection problem.

Luckily, with innovations like 3D printers or Polycaprolactone the entrance barrier for hardware is becoming lower, too.

Can someone tell me the difference between Sugru and products like InstaMorph (polycaprolactone)?

Other alternatives would include 3D-printed soft jaws, soft jaws molded with a low-Tg polymer like polycaprolactone, or an adhesive workholding system like Blue Photon.

Personally, I used a bit of polycaprolactone to form a hard plastic part that is formed on the nose and on each cheek and which: 1.

I guess in theory polycaprolactone might work, too, and as you say, poly(lactic acid) is a popular modern choice, sometimes painted or sanded to smooth out the print lines.

It also lists polycaprolactone, which melts around 70° and can be easily molded by hand while molten, as "Fair".

Have you used polycaprolactone/PCL aka "InstaMorph" for hobby/projects?

Polycaprolactone is actually unbelievably strong in one particular way: its fracture toughness is astounding because its elongation at break is usually over 1000%, higher even than polyethylenes.

Polycaprolactone is a plastic which softens at around 60 degrees Celsius, at which point it is possible to mold/form it by hand (skin contact is safe, and it's safe to let it harden on one's skin).

Polycaprolactone deserves a mention because above its glass transition you can mold the thermoplastic with your bare hands, but pouring it into a mold is out of the question because of its high viscosity, and as a result of that low Tg you tend to get a lot of creep, and parts become unusably weak in a warm room.
