This story extends from my last blog post (click, HERE, to view)....   It wasn't long before the simple models printed on my new Printerbot "Simple" did not meet my expectations. View the pictures below: First off, the picture on the left represents a series of prints cancelled mid way through the process. What you'll notice is that the texture of, what should be a gem of a 3mm cube is all smashed together. This is the result of the Z probe (the up and down movement) not being calibrate ...
My third blog in the series "Reaping the Rewards" focuses on the cheerful topic of successfully printing 3D objects. You'll notice that this post is considerably more "rosy" than the trials and tribulations and the quirkiness of my first impressions with the Printerbot Simple Metal.   Once you get your machine working (and trust me, I know how annoying this can be) the Printerbot website recommends that you print the "fan shroud." At first I didn't really know what this thing was, or what ...
Inside the combustion chamber, propellant burns at more than 5,000 degrees Fahrenheit. To prevent melting, hydrogen at temperatures less than 100 degrees above absolute zero circulates in more than 200 intricately carved cooling channels Cooling inlets are visible along the top rim of the chamber. Source: NASA/MSFC/Emmett Given In a rocket’s combustion chamber super-cold propellants are mixed and heated to the extreme temperatures needed to send the rocket into space. Recently, for the ...
This pair models a tank top and skirted created with the printer (via Electroloom) The numerous uses for 3D printing keeps growing. Aside from making prosthetic arms and edible foods, the technology is being used to create clothing you can actually wear. Introducing Electroloom, a prototype 3D printer that uses an electrospinning method to turn a liquid composed of a custom poly/cotton blend into a seamless fabric. The machine, though still in very early stages of development, can create cl ...
Part of the not-so-nice experience of having orthodontic work done is chomping down on the clay-like material called alginate the dentist makes you bite and keep in your mouth for about three minutes until it hardens to make an impression of your teeth.  Sometimes you might even have to come in a few times to make these impressions, which are then be packaged and shipped to a laboratory.   Wouldn’t it be nicer if somehow your teeth could be, say, scanned and a model made for a 3D ...
As this is the first time I write on these pages, let me shortly introduce myself: My name is Giuseppe Finizia, I'm an electronic engineer and I work in the Scientific Investigations Department of the Carabinieri (italian police). In particular, I am the senior analyst of the Electronic Forensics Unit of Carabinieri and I deal with technical investigations on seized electronic devices. So I spend almost all the day in a well equipped electronic laboratory. However, very often I felt the need of ...
