"Strength: 3D printed parts are not as strong as traditionally-manufactured parts. [...] In 3D printing, you are building it in layers -- this means that it has laminate weaknesses as the layers don't bond as well in the Z axis as they do in the X and Y plane. This is comparable to a Lego wall -- you place all the bricks on top of each other, and press down: feels strong, but push the wall from the side and it breaks really easily." - Andrew C (✓)

"Speed: Many people say that 3D printing is quick -- this is another omission of a suffix -- this time 'for manufacturing processes'. [...] The notion of 'but it'll get faster in the future' is not necessarily true, as we are limited by the chemical properties of materials such as ABS and PLA -- these materials can only be extruded so fast, and at such a rate before you start to destroy the properties of the part. This is happening with the top-end machines right now for FDM (Fluid Deposition Modelling)." - Andrew C (✓)

"Materials: Generally speaking, you can only print in one material, and this is generally a plastic. Now look around you...how many items are in your room that are made up of a single piece of plastic -- just plastic, nothing else? [...] Most items in the house are made up from multiple materials, and most of them are both metal and plastic. Those two cannot be made together as their melting temperatures are hundreds, if not thousands of degrees apart. I'd not like to smelt in my living room either." - Andrew C (✓)

"A great analogy I once read was the comparison of 3D printers to the bread machine." - Andrew C (✓)

I'm guessing that this is from a consumer 3D printing point of view. They are using 3d printers to build large parts of the next generation of heavy lifting rocket engines using metal based processes. But yes, as they point out, modern manufacturing processes are complex and can't be replicated through a single system such as a plastic 3D printer. - Scoble, Alex Scoble

I've always imagined that the primary benefit of 3D printing (for quantities of more than a handful) would be in producing and accurate prototype (or set of prototypes) which could then be used to create more traditional molding forms for mass production (using more durable materials.) I suppose direct-from-CAD milling machines can do this as well, but producing a 3D prototype... more... - Jkram|ɯɐɹʞſ

My brother Rob bought one. He's still calibrating it. His first project is a replacement lid holder for a saucepan where the knob on top broke. For all the hours he's put into it so far (researching and buying a printer and supplies, assembling and installing it, calibrating -- probably six more hours to go, I'd say, given how warped the current pieces are -- and learning the modeling... more... - Stephen Mack #TeamMomo from iPhone

Don't think I'd want a 3D printer, except maybe for printing objects in chocolate. - April Russo

^ !!! :D - A. T.

At a Maker Faire a few years ago, I saw a Makerbot modified to print either chocolate frosting or ganache. - Andrew C (✓) from Android

How are you feeling now? - Marie

How long was the nap? - Bren from iPhone

Is it possible to feel any other way after a nap? I mean, I can hardly recall a time I didn't feel like I was hit by a train after a nap ;_; - ani

The length of the nap can cause this. If you sleep between 30 and 90 minutes, you enter a deeper sleep stage from which it is more difficult to awake fully. This is why naps of that length make you feel groggy and zombified. - Bren from iPhone

It's 4:37 am and instead of going to sleep I'm talking about naps! \o/ - ani

Mine left me the same way. - Russian Space Lizard

Length definitely matters. My naps are usually 3 hours because that's how long it takes me to get into REM sleep and back. Short 15 min "rests" I can usually do but anything longer than that but shorter than 3 hr leaves me groggy. - Spidra Webster

The things that I knew would irritate me still irritated me though. - Victor Ganata from iPhone

As long as there's no unobtainium, right? - Scoble, Alex Scoble

I was appreciative though somewhat disturbed by how Shatneresque Chris Pine appeared - Victor Ganata from iPhone

I don't know about the whole Deus ex Real Spock thing. - Victor Ganata from iPhone

OK and now I hope that Deus ex Real Spock enters into the general lexicon. - Scoble, Alex Scoble

I was never disturbed by unobtainium. They could've called it macguffinium and that still wouldn't have been the thing that broke my suspension of disbelief #wrongmovie #OldSchoolSFShoutOuts - Victor Ganata from iPhone

But now I really want to see Elysium. Just the visuals of a reconstruction of a terrestrial world on the inner surface of a space station look pretty cool. - Victor Ganata from iPhone

maybe if J.J. does Star Wars up the pooper then Neil Blomkamp can have a whack at saving Trek? - Hieronymous Boosh

Actually, googling "deus ex Spockina" will yield relevant results. - Victor Ganata from iPhone

I honestly can't imagine JJ Abrams possibly ruining Star Wars worse that George Lucas already has. I already know I'll enjoy those movies more, because my expectations are already so low. - Victor Ganata from iPhone

Like, if he literally turned it into a Star Wars/Star Trek crossover based on a fanfic he found on the Internet, that would actually be an improvement. - Victor Ganata from iPhone

"Saenz, a 33-year-old father of two, used the GI Bill to enroll at USC but midway through his studies, the Navy pilot was called to be deployed to Afghanistan. After getting approval from his professors and Navy commanders, Saenz spent his final year of studies racing to his computer on base at 5 a.m. to attend the live transmission of his classes before dedicating his day to overseeing... more... - Anne Bouey

"Even getting to finals was treacherous.

I have such admiration for these guys and gals pursuing a degree under these conditions. - Anne Bouey

I will never complain again. Hot. Damn. *salutes* - Hookuh Tinypants

Like my Murakami. :) - Kelli H. from Android

If he's lost, the local grocery store doesn't have their bulletin board anymore, so I'd have to check the post office. But he could be part of the clowder that belongs to the lady up the street. Either way, I can't get him neutered under the local shelter's stray program because he's too friendly. I'm afraid to end up with a back yard full of kittens like last year. :/ - Heather

I think orange fluffy cat is preggers. I wish I could catch her and bring her to the local shelter, but I can't afford to. I have the time to do something about the feral cat population, and I have the resources I need. I just don't have the cash. ($35 if she's feral for TNR, $85 if she's friendly) - Heather

Wait - they charge you to drop off a stray? - Katy S

Yes, they do. - Chris Topher

Around here we can just drop them off. If you need a trap, they'll charge a refundable deposit for use of one of theirs, but there isn't a charge for dropping off animals. - Katy S

If you turn left just before the river, you'll end up on the road you can see in the photo. That's a good one too. For this view though you'll want to turn left a little bit after the river, on Requa Road. - Amit Patel

I love this area; I try to visit at least once a year. I usually stay in McKinleyville. - Amit Patel

I haven't been there since the '80s but I loved that part of CA. We were bike riding from Brookings, OR to LA and it was a helluva way to see it. - Spidra Webster

One of my favorite places in the world. If Arcata isn't too far off your route, you have to go for a soak in the hot tubs here: http://cafemokkaarcata.com/ - Meg V. Meg

Why are the gas companies targeting your state? - Janet:#TeamMonique

I know this is nothing compared to European prices, but when you have the crappy intercity passenger (non-auto) transportation system/infrastructure that we have in most of the U.S., it's a shock to the system. An increase of nearly a dollar in about 3 weeks, because of some 'maintenance' at multiple refineries that just happens to coincide with the onset of heightened summer travel? I... more... - Jkram|ɯɐɹʞſ

There's a major refinery in the souther Twin Cities metro that supplies gas to much of Minnesota and western Wisconsin. They're claiming reduced capacity due the fuel mix changeover, but won't disclose any details due to "anti-trust issues." Senator Amy Klobuchar is calling for the Dept. of Energy to review that whole thing. - Jkram|ɯɐɹʞſ

Your gas prices made national news. - Janet:#TeamMonique

What are the normal prices there in other cities? $4.09 is the price around here currently. - Stephen Mack #TeamMomo from iPhone

$3.29 here for regular. http://www.pennsylvaniagasprices.com/ - Janet:#TeamMonique

It's $3.99 - $4.09 for 87 here. I saw it as high as $4.39 in the Valley. - Anika

When I filled up my tank on Thursday it was $3.94 for 87 (or 89) octane. The previous time I filled up it was $3.54. After the drive to/from the Twin Cities (I'm back in E.C. now) it's likely I'll pay $4.20 or so. (We're not quite up there where Minneapolis is.) I'm just glad I can ride my bike most places that I need to go, and only use the car for out of town trips, etc. - Jkram|ɯɐɹʞſ

How about shoes for hats? - Scoble, Alex Scoble

Don't be all mad just cuz you've got a huge noggin. - Marie

In my family, we're evenly divided. Half of us are pinheads, the other half are fatheads. - Betsy #TeamMonique

I've never noticed much in the way of extras when I get things through amazon prime - they just show the individual episodes in my experience. - Katy S

Yeah, I read that as "DVD". My bad. - Spidra Webster

It would be nice, but really, I'm happy to just revisit a few episodes. - Katy S
