--- Quote ---For example, Lipson said, users could choose from a large online database of recipes, put a cartridge with the ingredients into their 3D printer at home, and it would create the dish just for that person. The user could customize it to include extra nutrients or replace one ingredient with another.

I don't think the drugs are premade, well maybe the 2nd generation 3-D printer does that, but the 3rd generation has already some pre-installed cartridges (small C O H N tanks) inside of it. We must access the database or the software to write the source code somehow...

The drugs are pre-made.  All this machine does is lay the drug out from a solution and dry it into a shape.  It says so right in the article.

The is no way to have a tank of C, H, N, & O.  & there never will be.   Even the Burke synthesis machine requires appropriate (and expensive) building blocks of reasonable conplexity.

Scarecrow:
Yep. There is no way it is possible, being able to program a molecule shape, and have a 3d printer build it out of C H O N P. What would be your source of atomic carbon? You would have to have sources of nucleophillic everything and also have a program that can somehow calculate the reactivity of the molecule as its being built and use different reagenets depending on the molecule lol if this is possible its far beyond anything biotech/nanotech is heading towards in the foreseeable future. Maybe once we have quantum computers and finally become buddies with our reptilian overlords

Scarecrow:
On a good note, itd be pretty sick for us bees to make custom pills with one of these

--- Quote ---They found that when the surface area of the printed tablets were all kept constant, the drug release rates were the fastest in the pyramid shaped tablet, followed by the torus, cube, sphere, and finally the cylinder. This order is directly correlated with the tablets’ surface area/volume ratio, with the pyramid tablet having the highest value and the cylinder the lowest.

--- Quote ---Drug release kinetics from tablets showed no dependence on the surface area but rather on surface are to volume ratio, indicating the influence that geometrical shape has on drug release profile. Tablets of similar mass showed little difference in dissolution profiles that could be explained by the erosion-mediated process that drives the drug dissolution.

maybe a pill logo in the future...  :)

Vesp:
Isn't that chart showing the opposite of what the text is saying?
Pyramid is slower?
