EEVblog #237 - Makerbot Thing-O-Matic Unboxing
When was that live scheduled. Didn't saw it coming tbh.
Alexander. -
I've been digging into 3D fabrication recently, thinking I might be able to utilize some of these hobbyist solutions for my own projects. So far the precision has been underwhelming. A video posted on youtube by the designer of the Prusa RepRap showed a considerable gap between an M8 hex nut and the socket formed by the RepRap to fit it in.
I haven't seen anything similar for the MakerBot yet, but I wouldn't be surprised if it was out there.
While doing all that poking around, somewhere along the line I was given the impression that the Makerbot offerings were based on the RepRap and they'd basically just done the hardware equivalent of a fork. After watching the unboxing video that doesn't seem to be the case. The RepRap is designed with the intent of being able to replicate itself at least to some extent (obviously you can't make stepper motors out of ABS or PVC), while the Makerbot stuff doesn't seem to have any of that. I'm really not a big fan of the laser-cut wood.
Other stuff I saw that was interesting at least on some level: the HP DesignJet 3D, apparently only available in Europe for the price of a low-end car, and one guy who was building an SLS (selective laser sintering) based system as opposed to the FDM (fused deposition modeling) system that RepRap and Makerbot employ.
Of course, every time i hear "maker bot thing o matic", it reminds me of the old mattel Thing Maker. -
I think it would be asking a little bit too much, but I would love it if Dave could film some of the assembly process too.

I am betting there will be a time lapse video.

This is very interesting
i could make parts for my custom made guitar pedals that i sell to people if i had a 3D printer instead of using off the shelf parts. The wah pedal is very difficult to make yourself because you cant get the parts for the rack and pinion assembly and have to buy a cheap volume pedal to modify and add my electronics to it.

What's that thing in the background on a stand/tripod?

Thats a support for a light source. You can mount 4 100w bulbs in it and illuminate something you want.

Ah, yes. I see now, thanks! -

Yes you can already do that, but you would have to build one of the (more or less) scalable 3d-printers. For example a RepRap. The problem is, that the build quallity isn't quite there yet. Your customers will still see, that your pedal was made with a fdm-3d-printer. -
I don't know about you, but it is still to expensive, especially when you consider its structure is mostly made of wood even without any varnish.
An accidental water spill on the wood can make it bend.
It's fine for something hacked at home, but for something for sale at this price point, I guess a laser or water jet cut aluminum sheet would be expected. -
will it accept autocad designs.
-
Here you find some exaples. http://wiki.makerbot.com/how-to-print I think it's some kind of gcode.
For some it is still to pricey, but what you can do with it is great. -
Pretty smart of Makerbot sending it Dave, free advertisement

The stand for a studio soft box. I have two of them.
Handy for lighting more critical photo/video work.

I have built my own 3d printer It took about 2 months of weekends and waiting time cost about $700 and was the first time I reflowed my own pcb. I can understand why Dave bought a kit as it is a pain sourcing all the parts and postage is a killer.

I didn't buy it, they gave it to me.

Then that was a late Christmas present.

Dave mentioned (rather briefly) the changes in packaging/padding materials, and I though I'd elaborate a bit since I ran into similar mysterious materials a while ago and wondered how they came to be...
First consider older padding materials, like the foam peanuts or bubblewrap. These work pretty well, but they already incorporate a large percentage of air (by volume.) that means they take up a lot of room in the factory, and they take up a lot of room being shipped TO the factory, both of which may be a substantial expense.
So a better idea is to send out plastic tubing, and inflate/seal it as needed for shipping. this results in those big "air pack" bubbles, which are pretty cool.
But plasitc of that sort isn't very "green", and is more expensive that the cheaper grades of paper (those already recycled at least once.)
So the next class of packaging material machine takes as its input a big spool of paper (say, 3 feet wide and 18inches in diameter - a hundred pounds or more of paper), and runs it though a machine that produces "crumpled paper" suitable for wrapping fragile goods.
The digikey wrapping is another step up. TWO kinds of paper, one of which gets criss-cross cut into a sort of net, co-extruded with a plain sheet of paper. More empty spaces, less actual paper. Saves the company money, and starts out as the same dense spools of paper, so you go longer between changing spools too. And of course the product is recyclable with other papers, and the source is also already a recycled product, so its relatively "green", but with the sort of repeatability and user efficiency you don't get from sending kids out to the garage to crumple up last weeks newspapers.
Some of the technology being developed is actually rather neat. Here's one vendor: http://www.geami.com/protective-packaging.html

Ah, so the box was containing some extra stuff just for you? If someone buys the kit He will find inside all those things (all those plastic threads)?
Alexander.I didn't buy it, they gave it to me.

What's the damage for one of these things?
-
I was watching this thing on youtube and i swear i could almost smell the plastic... MMM!

Sorry, I don't know exactly what you get in the standard kit.
But presumably only the stuff that had "Dave" written on it was extra thrown in for me?, I'd expect you'd likely get everything else.

Hi Dave,
Could you PDF the BOM an put that on the forum so we can see what is part of the kit?
Thanks,

Here is a good test print http://www.thingiverse.com/thing:9710
you should be able to have the tipper tipping and the wheels should spin
If u need help with printer u can email me denominator at hsbne org
Others if you scrounge parts and make some you can build a printer for next to nothing especially if you know someone with printer that can print parts for you. -
I have come across 3D printers via my employer. I saw a complete bicycle chain made using the process and all links were formed in situ with no post production assembly. It was amazing and the chain worked perfectly..... BUT and it is a big BUT.... the actual material used in the 3D printer process is not UV stable and is very brittle. I was advised that it was good for prototyping to show a customer what something will look like or test a CAD design in the real world, but it is not durable enough or suitable for production. I think CNC is the way to go to make production pieces.
The unit I saw working was probably this HP product....

I can't remember the model but the unit looks the same.
