Geek Tool: Slashdot Video of Award Winning 3D Printer From CES
The Makerbot Replicator is a personal 3D printer, which can create three-dimensional objects through connecting and layering successive cross sections of material. The new version is bigger, better, and easier to set up than earlier MakerBots. In this video Tim made at CES, MakerBot CEO Bre Pettis shows us how wonderful a device it is, and tells us why every child (and most adults) should have a MakerBot.
Read TFL. It's available now, it costs $1,749.00, and the feedstock costs about fifty dollars a spool.
I'm old enough to remember when discussions on Slashdot were well informed.
In the makerbot store there are ABS, PLA, and water soluble PVA filament spools.
I assume ABS is the plastic we are used to seeing everywhere that is fairly durable and water proof and that the water soluble PVA is the corn product he talked about in the video.
PLA is corn based.
PVA(polyvinyl alcohol) is made from polyvinyl acetate, which is made from ethylene, which is made from steam cracking petroleum. Not very renewable, but good as a wash-away support material.
Imagine what damage this will do to the industry. Everybody making their own things, nobody buying toys, nobody buying anything. Heavy copyright lawsuits must kick in to prevent this horrible scenario. Every model copyrighted, every 3D printer with online DRM.
Seems kinda limiting. When I look at these machines I see the potential to make all sorts of stuff that normally I would have to contract out to a machine shop (which for 1 or 2 of an item is not very cost effective)... but if the thing is going to start breaking down after a few months or years that kinda limits applications.
The two standard printing materials for the RepRap family of printers (and their descendants, like the MakerBot) are the biodegradable PLA, and standard petroleum-based ABS. PLA will degrade over time, but only under certain environmental conditions; it's unlikely to fall apart in normal use (most industrial thermophilic composting processes run at pretty high temperatures (60C and up). I guess you probably shouldn't use it to print an industrial composter.
ABS is ABS, and whatever you make with it will be around forever, so print your PLA composter with this instead.
i know a couple of people who use 3d printers. when they want to make parts that need to be stronger than the PLA/ABS raw material, they "simply" print the model, use it to make a mold and cast the mold with bronze or copper or what have you.
it stops being an all-in-one solution but still allows detailed custom shapes with good strength and appearance.
