3D PLOTTING (from Sanders, not Saunders) involves printing a
part encapsulated in support material (which melts away)
using a machine with three axes of motion. Z registration
is accomplished using a horizontal mill.
Ballistic Particle Manufacturing involves
printing a part supported by a break-away struts using a machine
with five axes of motion (the nozzle has two rotational degrees
of freedon). Z registration is accomplished using an ironing
pin. Parts are made hollow (although the interiors can be
filled with hatching to strengthen the part.
> 2) Does anyone know the status of 3D Printing from (MIT)?
3DP is alive and well. Licencees of the technology
include Soligen, Z Corp, Therics, Extrude/Hone, Hasbro
and Specific Surfaces. Research on 3DP is continuing
here at a rapid clip, with excellent results. Applications of
the technology range from oral dosage forms to rotors to
injection molding tooling (i.e. end-use parts). Sorry about
the outdated web page.
