Breaking Up With MakerBot
An anonymous reader writes "Sanders Kleinfeld explains how his experiences with a Makerbot device led him to the decision that 3-D printing hasn't quite arrived as a legitimate, consumer-friendly technology. Quoting: 'Waiting five hours for your Yoda feels like an eternity; you can play approximately sixty rounds of Candy Crush Saga in that same timeframe (although arguably, staring blankly at the MakerBot is equally intellectually stimulating). To make matters worse, I’d estimate MakerBot’s failure rate fell in the range of 25%–33%, which meant that there was around a one-in-three chance that two hours in, your Yoda print would fail, or that it would finish but once it was complete, you’d discover it was warped or otherwise defective. ... The first-generation MakerBot Replicator felt too much like a prototype, as opposed to a proven, refined piece of hardware. I look forward to the day when 3D printers are as cheap, ubiquitous, and easy to use as their 2D inkjet printer counterparts.'"
"Waiting five hours for your Yoda feels like an eternity"
I just realized why online retail will never completely beat brick-and-mortar.
"First they came for the slanderers and i said nothing."
In fairness to Makerbot, they can produce resolutions that the Ups can't touch - I operate both in my student labs. That said, because the Makerbot Replicators 2Xs we're using are 'higher performance', they're also much more finnicky about working until you've really cinched down on their calibration and preferred settings.
What we're really seeing here is the impatience of the Now Generation. What? You have to wait -thirty minutes- for something to be produced?? OMG!
Have these people any idea how long it takes to produce something through conventional CNC, let alone hand fabrication? I have fabricated parts that have taken 24 hours for a mill to produce. That's a lot of angry birds, right there! The ignorance of what goes into the technological artifacts people take for granted is astonishing. I suspect many people today would benefit from activities and hobbies that reward patience and discipline rather than instant gratification.
As an aside, It's interesting that the author uses a time killing game as a yard stick for the waiting period - as if the time spent while printing was 'dead' and couldn't possibly be used for anything productive.

Well, that's a tiny bit of an exaggeration. The harsh reality is that a 3D printer is a cool, fun, convenient way to make one-off and limited runs of plastic parts that would otherwise have to be injection-molded or extruded.
Yes, I know some systems can print starch that dissolves so you can (sort of) end up with spaces and gaps in the finished item, but in the real world, it's basically up to you to drill the precision holes, sand the rough edges, remove the burrs, and do the actual assembly yourself. We're a LONG way from "download the plans to some finished consumer good & stick it to The Man(tm) by printing yourself an unauthorized copy".
Buying a hobby-grade 3D printer today is kind of like spending $800 to buy a copy of Sculpt-Animate 4D for the Amiga 3000 20 years ago -- full of promise, totally cool, and the greatest Christmas gift someone could possibly get you... but at the end of the day, frustrating as hell.
Back then, you'd spend days, if not WEEKS, defining 3D objects, start a render at 2am before going to bed, crawl out of bed the next morning for school, be happy that you weren't greeted by 30-40 scanlines of black (indicating that it didn't like your lighting for some reason), spend the day at school praying obsessively that you'd be greeted by 2/3 of a badly-rendered image when you got home instead of a guru meditation number, and if you hit the jackpot... your preview didn't look like total shit, and vaguely resembled whatever it was you were trying to render.
A few days later, you'd go to render a raytraced preview the size of a postage stamp, then go away for the weekend, because that's about how long a 16-25MHz A3000 took to render a 80x50 thumbnail. Assuming it didn't crash, and there wasn't a thunderstorm to reboot the computer. OK, months passed, and you're about to go take a 2-week family vacation, so you launch into the Holy Grail -- a 320x200 HAM animation with 8-16 frames. You start the rendering job, go away, come home a few weeks later... and to your despair (but non-surprise), are greeted by either a guru meditation number or a rebooted computer courtesy of Florida Power & Light.
You screwed with it a few more times after that, but the magic was gone. The blue smoke evaporated. It just took too damn long to render anything meaningful, and the program had an 80% chance of crashing before it finished anyway. And when it didn't crash, it was Florida before UPSes became affordable, so 2-second power outages were almost guaranteed to nuke any multi-day rendering job before it finished even if the program DIDN'T crash. Such was life on the bleeding razor's edge of computer graphics ~20 years ago. Sigh.
I remember when CD writers were like this, about 25%-33% you tried to burn were coasters because your machine couldn't keep the write buffer full, so you had this delicate balancing act of setting it to burn and OH GOD DON'T TOUCH ANYTHING and hope for the best. They still blew my mind with how handy they were, and now CD/DVD burners are so dirt cheap and reliable that it's hard to imagine the days when they were so sensitive. I figure in a few years, 3D printers will get similarly more reliable and mainstream, and continue to fall in price, until people are churning out all sorts of widgets without giving it much thought or worry.
