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.'"
Half of the fun of 3D printers is getting angry at them. If you want one to "Just Work" you are out of luck. Some are better than others, but they all are basically hot glue guns with some servo motors, there is no feedback, no control. You can however, print some really cool stuff. Sure I would not let my parents buy one, but I have loved mine personally.
"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."
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.
That's his point - for the purposes of using the makerbot, it is dead time. You can't iterate before you have something, and you can't have something for 5 hours with a 33% chance that hardware failure was the problem and not the design.
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!
That's basically the same as having to wait 5 hours, right?
Have these people any idea how long it takes to produce something through conventional CNC, let alone hand fabrication?
How many amateurs are willing to burn virtually all of their free time for a day to do those things? Very few. Comparing your professional abilities and patience to his amateur abilities and patience is unfair (to put it very kindly).
Interestingly, I was talking to some Airbus designers, and they mentioned that they 3D print brackets used in ailerons out of sintered titanium. If they tried to machine the same part it would either weigh twice as much or cost twice as much for all the machining to lose the extra weight from its complex geometry. The 3D printing process let them only put material in the key loading directions the part had to be strong in, and nowhere it didn't. It made for a much better part.
