Title: Doubleshot DSA profile backlight compatible key caps. (in search of)
Post by: MarcWWolfe on Fri, 08 December 2017, 14:56:27
I've googled the **** out of it and can't find any. Please drop a link if you find some.

I've never seen/heard of DSA keys with a translucent shot (backlit compatible), only OEM profile: https://mechanicalkeyboards.com/shop/index.php?l=product_detail&p=1329 https://mechanicalkeyboards.com/shop/index.php?l=product_detail&p=1330

I *think* Signature Plastics could manufacturer ones w/ a transparent inner-shot, but I don't know of anyone who has done it yet.

I own double shot dsa caps that are windowed, but I don't think that is what you want.

The 1u caps are double shot gray+transparent. The letters are pad printed.

The multicolored keys are double shot printed.

have never actually seen backlit dsa before

Shine through DSA keycaps.. Maybe if you know someone with a dual extrusion 3d printer and lots of patience; then perhaps shine through dsa could be a thing. The opacity wouldn't be as clear as double shot injection though. Not to my knowledge.

Well apparently the font is centered so even if they did it, only half the font would be lit well.

You're right it's not unfortunately :/

I have tried 3d printing caps... it is not a good result.

It is fine if you are using it as a mold, but the issue is that the caps are too brittle along the seam lines. Printing them at an angle to stagger the seam lines helps, but produces artifacts and a generally ugly appearance on the top without a lot of sanding. It's not as easy as pressing a button and waiting, get ready for some work.

However, if you are using a stereolithography or DLP 3d printer, your results would be much better. As it is, traditional 3d printers aren't really optimal for the job. However, I did print a set of low profile DSA caps to see if I could, and it worked well enough for me to realize how they actually feel to use, but they turned out to be far too bittle at the stem, and nearly all of them eventually broke.  The solution isn't really to beef anything up either, there are tolerances you have to stay between, so you only can make it so thick in places and still function as intended. I suppose if you used a REALLY fine print nozzle, printed VERY slow, and printed hot, you could better fuse the layers while minimizing warp and sag. However, you would still have a lot of sanding to do regardless.

Basically what I am saying is, it is possible, but the results would be fragile and require a lot of post processing work. It probably isn't worth it.

I tend to over simplify massive undertakings with words like patience. *shrugs*

Is that why people want backlighted boards. I always thought it was because they liked to disco dance while they typed.

[singing] Uh-uh, uh-uh / Stayin' Alive, Stayin' Alive

Seriously, though: If you take a little time to get used to typing without looking at your fingers, you can go a lot faster. Then it doesn't matter if you're in the dark, either. And as a bonus, you wouldn't have to track down these (apparently) hard-to-find keys. I'm just saying.

You have any idea how long that can take? I've only owned a PC for about 2 years now. The most typing I do is social media posts. I have gotten into the non standard typing habit of resting/hiding my left thumb on the front of the keyboard which is improving my muscle memory. I am working on that.
The problem is, I eventually plan to make more to sell, and want it to be easy for the customer to swap key caps when they remap the keys. I don't expect everybody to be touch typist like OLKB does with most of their preonics and plancks.
