As a former chemist and all-around maker, I love this and this bugs me all at once. I love the concept, but as others have pointed out, this is less a "periodic table" and more "grab bag of related things". You see these all over the place: foods, drinks, cars, etc. All table, no periodicity. Why are wrenches and drills strewn across three groups? Put the wrenches in one group, drills in the other. Impact drivers somewhere in between.
There's some vague grouping, but it's pretty hodge podge.
The way I would do it, is use electronegativity (tendency to give or remove electrons) as a proxy for additive/subtractive. Atomic weight is a proxy for actual weight/scale. Group I would be like clay forming (the OG additive process), concrete, FDM, SLS, injection molding, casting. Group II is a bit less additive, more bonding: hot glue, soldering, brazing, welding. Halogens hog out material: thermic lance, plasma cutter, laser, waterjet. Chalcogens: hand router, (power) router, lathe, mill.
Metrology doesn't add or subtract, so obviously that's your Noble group.
Transition metals are all the fasteners. Lanthanides/Actinides are all the weirdos. I'd also add a group for just the simple machines. I think it's more important to have groups, periodicity, and trends, than sticking to the exact shape/size of the periodic table of elements.
This is Theodore Gray too! Author of a bunch of books and posters on chemistry.
Well, you know what they say, if you want something done right...
