What's weird is the lack of unified electronic system.
Over here for example, you can simply transfer money to someone's account using their sort code (i.e. numeric bank id) and account number. We also have a related bill paying system.
One referendum, one general election. Both in favor of Brexit.
Oh right we're into la-la-land invention of reality. There was not a general election in favour of Brexit. That's a made up fact.
And the referendum was ruled to be flawed because of irregularities.
This is relevant, I promise. Just today, I received a Shelly H&T (humidity & temperature). They have s cloud service and spot, but explicitly explain that you can set it up purely locally. I did, and attached it to my OpenHAB installation.
Every IoT device should offer this option.
I've done my first test of buying a whole pallet of filament straight from a Chinese manufacturer.
I'm curious what the shipping is like. I've looked at Alibaba and Aliexpress for buying certain items, and over a certain size, the shipping is quite punishing. For something like a side channel blower (i.e. palette sized, 15-20kg or so), the prices are a lot better in China, but the shipping eats up the difference, to the point where local vendors are competitive price wise but with faster shipping and better certification.
I imaging if I was buying a container load it would be a different proposition, but it's one at a time at the moment.
it could be all junk - but if it's usable, the price advantage is insane. Like $3/kg for PETG at the factory gate (like $5/kg after sea freight and our 24% VAT). Versus local stores which sell for like $30/kg.
Yeah that sounds about right! There's probably plenty where it's really good, and you get a massive bargain. For me, the 3D printed parts are one of the lower cost items in the bill of materials even with brand name Prusament filament.
Yeah it's weird stuff. I've done a of normal fiber reinforced composites, and to me the filaments just feel like completely normal filaments with the same kind of different tradeoffs you get switching between plastic types, such as more yield strength, lower toughness, less surface detail rather than a whole new material like the macroscopic type.
I didn't know that about glass vs carbon. At the moment, I'm printing for business reasons so I'm sticking to things where I have a reasonable expectation of being able to get more of the same filament in a year's time. This limits the amount of experimentation from smaller suppliers since I can't rely on the parts if I can't reliably get the filament.
Really it's mostly Prusament right now...
The fumes thing is overrated - typical measured levels in a room printing ABS are in the ppb range
Fair enough. I've not got any measuring kit and the printer I used most for that is not enclosed, so I erred on the side of caution.
Main annoying thing is that ABS is hard to print. I mean, it's far from the hardest, that'd be something like polypropylene or whatnot - but vs. say PLA and PETG, there's a learning curve.
I never had thaaat much problem, but I was printing my own parts, so designing in part for printability. I always went for plenty of supports and when I was printing a lot of ABS, I had a dual head printer so I used tight supports in HIPS (yay more styrene) soluble interface layers.
I'm mostly printing Prusament Galaxy Black PLA at the moment, with a bit of CF-PETG. I've got a reel of polycarbonate blend to try out.
Wake me when we can have small, cheap gas/diesel pickup trucks like the classic S10, Ranger, Hilux, Tacoma, Brat, etc.
You probably do have them, they're called "vans": I'm pretty sure Ford sell their Transit series in the US. Here, they are available in many configurations, such as standard box van, flatbed, drop side, and optionally with crew cabs too.
A drop side van is the same as a 2WD pickup with a more flexible bed (because the sides drop too) and better forward visibility.
For stuff that sits in a car and likely won't warp in the sun, I just go ABS or ASA.
Either print in a well ventilated garage or get an activated carbon filter. ABS gives off toxic fumes, so take care. Otherwise I think it's a bit of an underrated plastic.
It adds stiffness and some creep resistance. It usually adds a bit of strength, but it's not like epoxy/fibre composites where the majority of strength comes from the fibres. It's A bit more strength, maybe 50% depending on the formulation and part, but often lower. But also, it depends on if you mean yield or ultimate strength.
It's also a good way of trading toughness and stiffness and yield strength. PETG is incredibly tough, not hugely stiff and moderately in ultimate tensile strength. But the toughness is such that the ultimate tensile strength is not that useful often since it's so distorted by then. CF-PETg is rather less tough, similar ultimate tensile strength but a somewhat higher yield strength and with less creep and more stiffness. It also maintains the excellent impact resistance of PETG.
I can't speak for Europe / England and their repair laws, but everything in America is required to be approved by the FAA for use in aviation
He bought it at an airshow in America.
A part they bought at an airshow?
