Ok, interesting #CGAPrints / #Thrixels update today. The last few colours - brown, grey and dark green - have come out with noticeably crap quality, probably my printer needs some preventative maintenance after churning out thousands of the same part, but also I should probably build in more tolerance because different filaments are going to act differently.
I'll keep building this stockpile for early pixel art tests, but might revise for time investments in bigger projects. #3DPrinting

Making better progress on #CGAPrints just at the moment, despite it all. Here's an action shot of the light green ones getting printed - this is about four hours in. 34 seconds per part is still nine hours when you're doing a thousand of them at once! #3DPrinting
-
Progress on #CGAPrints is slow due to life and other stuff. A full print of 1k #Thrixels is ten hours, basically a whole printer day, and I don't like running it overnight, so if I don't get a plate started in the morning it's not a day this project gets furthered.
I'm up to five packs done out of 16, so in theory I could have the rest knocked out in a week. Realistically it'll take longer, but momentum is slowly building up!

A better photo of my 16 #CGAPrints filament collection, and my progress so far on turning them into #Thrixels for pixel art.

And now it's time for this project to go silent again for another couple of weeks. Next up is printing some 16x16 bases to do some test artwork, then waiting for a Storage Solution to arrive before I actually start printing ten thousand tiny parts in sixteen different colours. Hopefully I'll get to do a lot of pixel art in November! #CGAPrints #3DPrinting

#CGAPrints: Photographed here together for the first time (on a filthy garage rug, sorry) is all 16 IBM CGA colours reproduced in PLA spools. Ten months in the making, this has been a revoltingly expensive, stressful and tedious project, but lining them all up like this I had a hideous grin on my face.
Full list of chosen filaments in the next post. I do not at all recommend replicating this project, please instead live vicariously through these posts.

#CGAPrints Release Candidate 2. Magenta is now Atomic Filament's Perfect Purple, and a slightly lighter shade than in RC1. Cyan is also a little brighter in real life (it's devilishly difficult to take this photo meaningfully, so trust me on this).
I think it's time to line up some filament and print a thousand-odd #Thrixels of each colour, then do some test sprites to see how these colours actually work together!

@digga_mies I want this to be the base for some very large art projects - like replicating a screenshot from an old DOS game large. I have a parallel project #CGAPrints where I've been finding filament in the right colours to replicate the original IBM 16-colour palette, so once I have a good enough system of tiles and a set of colours finalised, I want to replicate something from an old game - Commander Keen, Hero's Quest, something with phenomenal pixel art.
-
Two 1kg spools of PLA is AU$50 without shopping around much at all, and given I already have a ton of PLA of all colours sitting around from #CGAPrints, I have more than enough material for this project already bought and paid for in my garage.
It would be more efficient in volume to use ABS - it's something like 20% denser than PLA - but a kilogram is a kilogram, and all my ABS is on old spools that don't fit my AMS, and I don't feel like re-spooling any of it at the moment, so PLA it is.

#CGAPrints update: Release Candidate 1? I took some time today to test-print some colours that arrived this week, and they seem pretty close. This is the first time I've compared a full batch of #thrixels against colours on a real screen - what do you think?
All 16 colours are different brands and types of PLA, so given access to the complete palette, basically every printer should be capable of making some form or other of CGA pixel art.

@misjavanlaatum @krystman as someone attempting basically this with #CGAPrints, I fully endorse this strategy 😅

#CGAPrints update: Push Plastic's Dark Teal PLA has entered the chat. Massive thanks to @filamentcolors for helping me get some of this to Australia without spending a fortune on shipping (despite the very best efforts of UPS)!
This stuff is almost exactly the right colour and shade for CGA teal, but is surprisingly matte for a plain PLA colour, doesn't love Bambu's default ironing settings, and jams at the back of my AMS, so this stuff will be exclusively reserved for making #thrixels.
-
#CGAPrints state of play at the moment. I have a new teal coming to replace the ProtoPasta Atikam, I need to find either a darker dark blue than Overture or a sky blue between Tecor Blue-Grey and Bambu Cyan, and I've found a great magenta except it's completely unbranded (not uncommon, this close to China) and because it's potentially un-repeatable, I don't want to commit to it. The blue and magenta I want to try next are both out of stock right now, so this is swiftly becoming an 80/20 project.
-
#CGAPrints update: A first attempt at cyan and magenta, and I'm not totally happy with either. The cyan isn't quite bright enough - not a huge surprise, since light blue is actually Bambu's own take on cyan - and the magenta's not even the *brand* I thought I was buying, so while the colour looks right at first glance, I don't know if it's a sustainable option. I think it nails the contrast with light red though!
Teal is at half mast because I have another candidate for that on the way.
-
Today's #CGAPrints update is bananas. Bambu's matte yellow PLA hits that middle-ground between Radioactive Banana (Bambu's regular yellow) and Traditional Lemonade (Tecor lemon yellow). To my eye there's even a tinge of brown to it, which I didn't expect, but it sets off the actual brown really nicely, so I'm calling that a match.
I'm still chasing CGA magenta and cyan in the palette, and I think I've found a brighter teal than Atikam, so there's still a ways to go yet.
-
#CGAPrints update: I've got the blues! Specifically, left to right, I've got Bambu cyan, Tecor blue-grey, Bambu blue, Overture "PLA Professional" dark blue, and eSUN dark blue. (All of these are PLA or PLA+.)
The Overture has become CGA dark blue, with Bambu cyan taking light blue - I'm hoping that some other brands' "cyan" is much brighter than Bambu's, otherwise I'll be digging into "toothpaste" and "ice" shades of blue to fill out CGA cyan.
-
#CGAPrints update: Tecor's Green and Lemon Yellow PLA+. The old 16-colour palette is really starting to come alive with these brighter colours - and it'll only get better, with fuchsia and cyan to come!
The light green is nice and vibrant, but the yellow is a bit too pale - I'll have to keep an eye out for something in between this and the Standard Radioactive Yellow PLA everyone sells.
-
#CGAPrints update: eSUN Dark Blue is too dark - it's so close to black I wonder why they even bothered. Everyone else's regular blue is too light. I may finally have to dig into the PolyTerra range - their Army Blue looks like my next best bet here.
-
#CGAPrints update: Light red (Tecor's Matte Red PLA) joins the party. Neither of the two reds in the 16-colour CGA palette really matches what you'd typically find called "red PLA", so finding colours a few shades up and down was always going to be a challenge - but pending adding more bright colours to compare, I think these are final.
Light red is especially important to get right, because it was used as a skin tone for human characters in Hero's Quest.
-
#CGAPrints update: Teal! This (top right) is #ProtoPasta Atikam HTPLA - say "Atikam" backwards and you'll see the original inspiration for the colour. It's a beautiful shade and fits perfectly (I think) in with the rest of the palette so far - which I'm super relieved about, because it came quite a long way to be here.
The hardest decisions are out of the way, so filling out the rest is just a matter of time as I pick up another colour or two as I go along.

#CGAPrints update: Dark grey (Tecor) added. I'm convinced now that I need to find a darker dark blue - regular blue is just too close to anything I like for light blue, and there's only so bright a cyan I can find, so I have to shove the blues down a bit from here.
I have candidates for all other colours as well, and will collect those as the hobby budget permits. This though is enough to start making some proper pixel art - that'll be my main project over the next couple of weeks!
-
Lots of #CGAPrints updates today. #BambuLab's Cyan and Mistletoe Green replace Tecor's blue grey (so it's lighter) and PolyMaker Green (so it's darker), and I've also added their regular blue (which I wish was a tad darker as well, but it'll do for now).
I have a candidate in mind for "dark cyan" but it's only available in the US, so it'll be a while before I stump up the cash for it. I did try Bambu's "Green", which is almost the right shade, but it's so dark I have trouble photographing it!
-
Here's my actual project for today - in preparation for greater #CGAPrints projects, here's the first large-scale test of my fully 3D-printed tile mosaic system #PixelArt thing. I have printed 600 tiles (#Thrixels? Timbits?) of each colour, and my goal is to assemble these into a meaningful pattern to test how a big mosaic might look. Any guesses as to what image will emerge here?

Today's #CGAPrints update is the addition of PolyMaker PolyLite green - it was meant to be here a week ago, but #AusPost decided it needed to spend Christmas in a warehouse in Darwin for some reason. (It only had to come to Canberra from Adelaide.)
This is tentatively the "dark green" - to my eye it should be a bit lighter than purple and dark red, which it is, and noticeable darker than light blue, but it looks about equal to me. I'll reserve final judgement until I have dark blue in place.
-
@_tt_ @3dprinting I'm designing a totally 3D printed system for making pixel art/tile mosaics - see the early posts about figuring out how it'll work here: https://digipres.club/@timixretroplays/111497377580106613
Eventually I want to combine this with a collection of filaments that match the original 16 colours from IBM PCs and turn it into retro gaming artwork: #CGAPrints
Follow along if that sounds interesting 🙂

#CGAPrints update 2, and the first elimination-by-comparison. Bambu's plain black, brown and grey have joined the party - I also tried their silver, which has a pretty sheen to it, but that also makes it a bit unpredictable in brightness, so plain grey wins out here.
The brown is also tentative - it comes down to combining well with others, which will take time to gather. I have one more colour coming before the new year, then some other projects will take priority for a bit. #3dprinting
-
#CGAPrints update 1: eSUN purple, and Bambu white and yellow. The yellow is a temporary placeholder as it's definitely not pale enough for the CGA palette - I've seen a couple of different brands sell a "lemon yellow" which looks like it might do, so that's on the shopping list for later. #3dprinting

This will be another super long-term project, but here's my proper inaugural #CGAPrints post. I'm seeking out 3D printing filaments to match the original 16-colour palette from IBM's Color Graphics Adapter (CGA), so I can eventually make some pretty #retrogaming art.
This is dark red, represented by eSUN's Fire Engine Red PLA, and light blue, which is Tecor Blue-Grey PLA+. These choices may change as I find and test more colours, but we'll see - I have more coming this week! #3dprinting
