surface finish

[paulsroom @paulsroom]

xtc-3d-brush-on-coating-for-3d-printed-parts I wonder if anyone has come across this surface finish material for 3D prints, and in fact if they have used it. In the description it says it is self-levelling and does not require very much to coat the surface, but I wonder if the thickness may affect the original fine detail in a 3D print. I would think that it is not suitable for 3D printed parts that have to fit together. But as a perfectly smooth finish on a large object, it seems like a useful idea.

If it fills in / smooths out striations then you will lose fine detail.

This reminds me of another question I wanted to ask. With my early prints, granted the Robox wasn’t behaving itself, you could pick away at the layers and unravel them post printing. In other words, the individual layers delaminated quite easily, meaning I could peel parts of the model away.

I wondered whether the process of placing the model in a jar of heated acetone (creating a vapour which smooths out the individual striations through a process that slightly melts each layer into the next) would add some strength to the model overall. Having those layers slightly chemically melted into the next would surely add a little more rigidity, although as already pointed out it would remove any fine detail.

waiting for AM to improve seems a better idea to me

Uh huh. You are, of course, correct. Fingers crossed not too much longer to wait. I can’t imagine coding for one OS is particularly easy, then add another two into the mix surely complicates things (that is Windows, Linux and Mac OS).

@David: AM is written in JAVA so they have to write the code only once because JAVA is available on many OS’s.
Maybe they only have to do minor fittings…

[pelgrim @pelgrim]

Coding java and javafx for different OS does not affect the programming at all when it concerns calculations, interacting with slic3r, processing gcode, communicating with the usb port, …
The only thing that differs is some technical details if you access non-standard hardware and the UI appearance, an OS has a mind of it’s own about t that.

So to put it simple: OS has no influence on print quality.

But don’t underestimate the complexity of the maths and translating the theoretical model into physical machine instructions,
I don’t really expect things to be right in 2014. We’re not talking about some small fixes here and there, but the basics that have to be solid.

Yep. We used to say that Java was “Write Once; Crash Everywhere”.

nope, saw nothing, java is good

Last time I did a big project in it was in the mid- to late-nineties. It might be okay by now.

ok, we’re way off topic, but who cares …
Java had its surface finish with javafx.

I stepped in the java 2.0 game end 2001, after years of frustration with bluescreens in the Micky$oft environment, Access no less, and everything that smelled like VB,
and a few years later I gradually changed to linux.
Never got a crash again while developping, and I never looked back again, although I must say the change to linux is a lot easier today than it was +10 years ago.
