3D Scanning By Shawn Wallace
Victor Freundt prints a project using the ZCorp printer at the Barcelona Fab Lab.
When working with 3D scanning and printing equipment, it quickly becomes apparent that objects are nowhere near as fungible as MP3s. We'll have to wait a while for the day when every teenager is capable of casually copying real-world objects. However, it is surprisingly easy to hack together a crude 3D scanner from commodity cameras, projectors, and hardware you probably have in a couple of junk drawers in your shop.
A good place to start is with the Modela mini mill, which has a piezo-based needle sensor attachment that can be used for scanning small objects. The machine records the plunge depth at the point it contacts the object and the software that comes with the Modela (Dr. Picza) converts these points into a 3D mesh. Here's an example of using Dr. Picza to scan a small shell from Benito Juarez from the Barcelona Fab Academy site:

Acetate
(fibre) (generic Name)
The
Term Used To Describe Fibres Of Cellulose Ethanoate (acetate)
Wherein Between 74% And 92% Of The Hydroxyl Groups Of The
Original Cellulose Are Ethanoylated (acetylated). Purified
Cellulose Is Ethanoylated (acetylated) By Ethanoic Anhydride
(acetic Anhydride) In The Presence Of A Catalyst (such As
Sulphuric Acid Or Perchloric Acid) In A Solvent Such As
Dichloromethane (methylene Chloride) Or Ethanoic (acetic) Acid.
The Reaction Proceeds Until Primary Cellulose Acetate Containing
60% Of Combined Ethanoic Acid Is Formed. Secondary Cellulose
Acetate Is Formed From The Primary Acetate By Partial
Hydrolysis. It Is Obtained By Adding Water In Excess Of That
Required To React With The Residual Ethanoic Anhydride, Which
Thus Allows The Hydrolysis To Take Place.
Acetone-soluble
Cellulose Ethanoate (acetate)
When
The Hydrolysis Of Primary Cellulose Ethanoate (acetate) Is

Acetone-soluble Cellulose Acetate.
