Small sand molds for aluminum casting were produced by selective laser sintering (SLS) of pre-coated sands. A diode laser source with a rectangular laser beam spot was used to perform single and multi-layer processing tests. Subsequently, small sand molds were produced and tested in casting operations. Single layer processing was performed by changing laser power, scan rate and distance of the ...

Although the oxidation of fatty acids by molds has received only superficial study, it has been found that Penicillium roqueforti forms methyl ketones as products of the oxidation. The distinctive taste and odor of bleu cheese is suggestive of 2-heptanone (Hammer and Bryant, 1937), and this compound, together with other methyl ketones, has been isolated from a ripe cheese and identified (Patton...
