Mostly cost & benefits over existing metal 3D printing technologies.
Current metal 3D printing machines cost well over $1 million, and have some significant caveats for part design. Due to the residual stresses in the parts, supports structures are required for many part geometries. This means your parts that have been designed to be unmachineable, now have support structures that then need to be machined off. The easily removable supports are a huge win for Desktop Metal here.
Repeatability has also been an issue in metal 3D printing. This is partly due to the nature of the sintering/melting process, but mostly because the majority of parts produced on metal 3D printers are actually designed to be manufactured using another process. I have higher hopes for the production system than the studio system for improvements in that area, but remains to be seen at this point.
Yes, but they haven't made it down to the automotive level yet.
Most automotive LIDARs just report the time of the first return, but it's possible to do more processing. Airborne LIDAR surveys often record "first and last"; the first return is the canopy of trees or plants; the last is from ground level.
It's also possible to use range gating in fog, smoke, and dust conditions.[1][2] Returns from outside the range gate are ignored. You can move through depth ranges in slices until something interesting shows up. This seems to be in use for military purposes, but hasn't reached the civilian market yet.
Range gated LIDAR imagers have been around for at least 15 years. By now, it should be possible to obtain a full list of returns for each pixel for several frames in succession, crunch on that, and automatically filter out noise such as rain, snow, and dust. It's a lot of data per frame, but not more than GPUs already handle. Some recent work in China seems to be working to make range-gated imaging more automatic in bad conditions.[3]
I find it funny that people can seemingly flippantly state that Tessa (or any of these cars) have "weak sensor systems" as if it is such a trivial problem.
"Well, there's your problem right there, let's just slap on some strong sensors and you should be good to go!"
You know what has a weak sensor system? Any car without any sensors.
Yea this seems like the key question. I don't know if Level 5 in two years is feasible, but if it's Level 5 or bust, then LIDAR won't fly (AIUI; would certainly welcome corrections).
On one hand, not pulling in potential safety improvements because they only work in good weather seems wrong, but on the other hand...that might be what needs to happen from a cost/marketing/legal perspective.
I wonder if flatter organizations with broader company decisions made through collaborative online discussion (ie. not face to face) would help? Obviously someone still has to make the call, but at least it lets people put their reasoning out there without dealing with the inefficiencies of meetings and the unequal opportunity they tend to entail for input.
The best way for men to counter this in a toxic environment is to call it out when they see it. This sends a message that being outwardly dehumanizing and dismissive is not okay, and is not the accepted norm.
I'm quite shocked that nobody stepped in when Mike2 called her a "whiny little bitch" in a meeting. She said the other men "were shocked" spare a couple that giggled. What the fuck kind of person stands around and does nothing when witnessing that kind of abuse in a professional environment?
When you put a lot of your self-worth in your job and you know that the person you're about to call out can have you fired on the spot? So probably almost everyone. It's really hard to call out the boss, especially when you know that no one all the way up to the CEO has your back.
Not saying it's still not the right thing to do, just, you should put yourselves in their shoes. Probably that entire room could have told the guy in unison "that wasn't cool" and they would have all been instantly fired, so, not sure what that's gonna do for anyone...
I've stood up for someone in that kind of conversation. Our boss was yelling at a colleague in an inappropriate way. I interrupted to defend the guy. Our boss said, "If you don't feel like you need to be here, you should leave the room." I left the room. No adverse consequences to my job, as far as I can tell.
I suppose I could have stayed, but I also figured my colleague could stand up for himself. He's not a pushover.
Honestly, the type that is afraid to be fired and doesn't want to rock the boat. I'd like to believe I'd stand up and say that's wrong, but never having been in the situation, I don't know how I'd react. I'd probably start navel-gazing, too. :(
Presumably ones that are themselves being abused/in an abusive environment, as mentioned all over the article? Plus, of course, the ones perpetuating that culture, but I doubt those were the ones whose silence you were shocked by.
"Anyway, if you look through the documentation, every time he wanted parts in the ‘70s he would hand draw the part. For example, a light bulb or a brake caliper, or whatever it might be. The sketches are so intricate they look like a photograph. He’d make multiple copies of his sketches and mail them out, asking shops if they had these parts."
By "hand drawn" do they mean freehand, or drawn with manual pencil drafting techniques? Because both are done by hand, and really most trained draftsmen produced drawings of that quality (even lettering would look like it was printed).
see also ikea. they had their modellers take photography courses and their photographers take 3d modelling classes IIRC. good luck telling renders from photos in their catalogue.
I can confirm this. Source: IKEA communications, their marketing arm, was a client of a company I used to work for. Not only were we given a lot of source material, but we also got to tour IKEA HQ in Älmhult, Sweden, whenever we went down there for meetings and the likes. It's really quite remarkable what they've got down there. Several photo and movie studios, with essentially a warehouse full of IKEA furniture from pretty much every era, in at least three copies I think they said. The 3d department in contrast was unassuming – just a few people (can't remember exact count, but I'd guess less than 20 at least) in a room doing amazing work. We'd spend a bunch of time looking at pictures playing "can you pick out what's rendered and what's not?" kind of thing. (Side note: this was around the time IKEA decided to switch to Verdana from their proprietary IKEA Sans font as well, and it was fun to get an inside perspective on it.)
I very much enjoyed working with them – highly professional people that really know what they're doing.
