This must be about the tenth iteration of the TIE Avenger. I tried to paint the initial models that I printed a couple of weeks ago, and they turned out to be so unbelievably fiddly that even painstaking masking (each one took an hour to mask) didn't give me a satisfactory result. The problem was that the gaps between the solar panels are less than 1mm wide, and getting low-tack masking tape to stick well enough to prevent paint getting underneath was downright impossible. I've also had the notion of this being something I could potentially even produce low volumes of for other people, and so making these easier to produce in the future was something I thought spending a bit of time on now would be beneficial.

... what followed was six hours of painstakingly taking the model apart so that I could separate each of the 28 solar panels into individual pieces, allowing me to paint them without the tedious masking process. I've also removed the cockpit window and hatch, as they proved genuinely impossible to mask properly, and I thought the easiest way of doing them was to simply make the centre of the ship hollow, and just remove the 'window' parts leaving the octagonal frame. I may want to paint the inside of the ship black to achieve the level of contrast needed to make it look right. I printed each of these two pieces four times just because they're so tiny that I anticipate breaking a few and I wanted extras.

I've needed a bit of a win after near constant frustration with the TIE model, which just isn't behaving. My brother's coming up this weekend, and I decided to print him the Shivan juggernaught Sathanas from Freespace 2 (he used to be a writer for a major Freespace 2 mod back in the day). I did the first half today, and I've got the massive mandible-like arms to do tomorrow.

It's by far the longest print I've done at 8 hours, and while it's not a perfect print, I'm pretty happy with how it turned out. It's an extremely complicated shape, and the slicing software gave it hundreds of tiny supports, which thankfully just peeled off for the most part. I've found that removing the supports before curing the print in the UV 'oven' makes their removal so much easier, but it does mean you have to wear gloves while doing it as the resin is still potentially toxic at that stage.

The wee man was away someplace with the wife today while I was at work and he got to fart about with one of those 3D pens...

Granted it's nowhere near your level Raid, but I thought it was pretty cool and it is technically 3D printing, albeit in a more crude, freehand form. :)

There's something inherently cool about those things, but I don't really understand what they're for. Are they intended as toys?

I printed the Sathanas' arms today. I made a few attempts at them earlier in the week, but they just would not print lying flat (which drastically lowered the print time). Because they were now standing up, I had the space to stick a tiny, vaguely-to-scale GTD Bastion alongside them on the build plate with no extra print-time-cost.

The Sathanas looks, I'll hope you'll agree, fucking awesome.
