Enjoying the vids Maxlvl. Worked in industry with both G10/FR-4 and Ultem 1000. Have personally machined G10. Have designed for Ultem 1000 and worked on the manufacturer's floor. Have extensively qc'd both. If you check the material datasheets, you'll find that G10 is a much stronger material mechanically and that bears out in my experience. It is a pain to machine. The embedded fiberglass wears down milling tools much faster than Ultem 1000. If I remember correctly, G10 is cheaper to source, but has significantly higher labor costs. I'm straying from the topic. Ultem 1000's claim to fame is effectiveness as an electrical insulator, good resistance to a variety of chemicals, good dimensional stability in humid conditions and machinability. Works well in stable, inert environments like electrical test setups, rigorously climate controlled and for the most part mechanically unstressed. I can't vouch for uv resistance as most industrial ultem equipment is sent to environments that hardly see natural sunlight. Its weakness is mechanical strength: poor resistance to chipping, scratching and especially stress-cracking. It was often last on my list of candidates of engineered plastics for applications where mechnical stress was a factor. It can be effective, but the technicians have to respect the amount of torque they put in assembly screws or the product would see early failure from stress-cracks around those points. And the engineers had to respect where they chose to introduce mechanical stress in ultem parts. This is accelerated in wide-temperature conditions, particular ice-cold temperatures. The material is brittle and failures from fractures / stress cracks are expected over the lifetime of the material. It'll work, but you can't fault the material for its limitations. I think electrical & chemical resistance was the goal for the original formulation. Ultem 1000 is a capable plastic in the right application, but in the EDC industry, a more suitable choice if a customer insists on ultem would be a glass-filled variant like Ultem 2300 which addresses the mechanical shortcomings. However since glass-filled variants are opaque, G10/FR-4 comes in far more color options. Anyway, most of this is common knowledge if you've worked in the electrical / manufacturing industry, but you can refer to the material datasheets via any search engine to verify. Personally, ultem 1000 accented EDC gear would make for nice garage queens, but for hard use, I'd think I'd like to have G10 or some other mechanically durable plastic. That however is just one product designer's experience so take it for what it's worth and put it up against other engineer's perspectives. I rarely comment if ever, unless the information is important for consumers, so hope this is informative. Thanks for all the vids. Your powerpint vid has led me to pick one up and correct its shortcomings to bring it up from C-tier to A-tier. A lot of potential that was left unrealized in that design, but it's actually a pretty good one. Edit: One thing I missed. Ultem 1000 is injection moldable. Not as cheap as something like nylon, but in theory if a design is popular enough, it could be made into a mold and cut down on production costs significantly. That may not apply to the EDC industry since a lot of offerings are somewhat bespoke or run in smaller quantities.

Like GoreTex. Other "brands" are fine and work the same for a fraction of the price.

There is a trend of adopting cheap materials and selling them as a “feature”. One prime example is Spyderco’s FRN; it’s marketed as “Hey, it’s lightweight!” Yeah, ok, it’s lightweight but cheesy as hell.

@larshoneytoast722

7 ай бұрын

Lightweight is a feature tho and they're cheaper than the g10 counterparts so that's not a great example but I do agree they're trying to market ultem as premium when it's basically just another thermoplastic

@XenFPV

FRN is mechanically strong and durable and grippy, and can be dyed in any colour. It's a great choice of material for a knife handle. Not sure why it's "cheesy" just because it's not titanium or carbon fibre or something sexier and more exotic.

I'd be interested in seeing testing on Ultem. A lot of KZreadrs are repeating marketing claims without much empirical evidence or time-testing. Does Ultem discolor over time? Lose elasticity? What elasticity does it have? For example I've heard the phrase: "it has it's own rockwell" without citing what that rockwell is. Every solid thing has a hardness. It just feels like this is one of those corporate driven trends that we need to think critically about on principle.

More like all of them 😂 They all get the same email with the same instructions They are great employees...

I bought the same full-sized Praxis in Ultem that is shown in the video, and TBH, it was an impulse buy. I've had it for a couple of weeks now, and it has grown on me. It feels good in the hand, and I now like the looks of it. The color under lights is very yellow, and gets a bit of green as it moves into the shade. As stated in the video, it's appeal is more visual, but I'm still glad I got it. Oh, and if your piss is this color, either drink more water or see a doctor.

FYI, be weary of ultem or PEI in general if you work around nastier chemicals, especially solvents. It's pretty good vs chemicals but nowhere near as robust as something like G10 or FRN

I think you do an excellent job with your content.

It looks like any white transparent polymer that turns yellow with time. Ultem just comes pre-yellowed. I can’t get over the “dirty old plastic” look, so it’s not for me.

I have not picked up anything Ultem. It looks kind of interesting. I may get something just to see how it is in person.

"It was invented in the '80s" makes sense cause it looks like some cheap clear plastic thing that's been faded in the sun since then.. I don't get it. Different strokes I guess.

There's an expensive lightweight gaming mouse brand called Finalmouse who uses Ultem in the bottom of the mouse so the wireless signal can get through.

I like the look of it. Guess I'm weird like that.
