[E2][A] I'm going to fight for 4 materials

A project log for SecSavr Soapavr [gd0146]

A grayscale 3D printer that's trying to be Betterâ„¢ than PolyJet.

Basically, if there's anything I could really use in the future, it's an on-demand PCBA service. Additionally, the allure for AME (Additive Manufacturing Electronics) has been much stronger for me than other features I've discussed in the #SecSavr Suspense [gd0105] project. 

Embedded components, motors, mmRelayArrays, programmable matter elements, etc. These are all things I'm interested in, but 2 materials is rather limited. 4 materials changes the game for these applications (such as being able to print iron cores to copper coils), as well as allows for black+white+alpha prints with (dissolvable) support material.

Now this sounds like feature creep, but honestly, I should just take off the mask all Fred-from-Scooby-Doo style:

Yes, this does mean that the Pick 'n' Placers are going to make an appearance in here too.

For an 3D printer the size of the SecSavr Soapavr, the limited Z height would also be much less of an issue for PCB fabrication.

[2024 - Jul 13

Because of how #Tetrinsic [gd0041] is (and has been) progressing this entire time, seeing complications with the Micronics printer (see below), and the mental overhead of also having to worry about leaving enough headroom for Future Me to add fast gantry for a (now £240 these days) 20W laser, I'm going to roll back to just trying to create a grayscale+transparency 3D printer, ideally one that's still large enough to print an A4.

One of the things I still remember from a Hanno Brawn interview is him saying this:

I don't know if it's controversial, but I live my programming life by one iron rule: that it's always okay to make a mess, but it’s never okay to build on top of one.
[...] 
So go clean it up, before using it as a foundation for your next masterpiece.

Basically, all the features I want still hinge on the base technology actually working, and I don't have that. And I still remember thinking that Tetrinsic would be a plain and simple ordeal -- actually, I still do but now I know a larger list of all the stuff that I need to get right. I see this as the "Discovering Items Percentage Effect", named after the times Windows Explorer started a large task, got to over 90% and then drops to 40% (for example) when it discovers an entire folder of files it needs to work on.

Back to the build volume, I had considered 160 x 320mm, but I still want to have the option of printing the 192mm #T^2 Tiles [gd0095] or, as mentioned earlier, a sheet of A4. The latter requirement was actually the reason why I got the CR10 back in Q4 2016 on Gearbest; it was a new printer with 0 reviews but also the only one at the time that had a print bed large enough for A4. Realistically speaking, however, it seems that I'd be stuck with the 8.9" 4K display as there are a fairly low amount of options that I can buy the LCD, UV matrix and HDMI conversion. It all seems to be a tad over £200 worth of parts.
