Only the surfaces that form a closed object can be 3D printed.
The closed surface model has to be converted into a solid
object, which is described by the .STL file. We have two kinds
of 3D powder printers - the Z510 and the Z310. The following are
the differences between the two printers. Z510 - x10 x y14 x z8
inch / 254 x 356 x 203 mm Z310 - x8 x y10 x z8 inch / 203 x 254
x 203 mm Z510 - can print in full 24 bit color Z310 - only print
parts in monochrome Because the Z510 uses a finer powder it has
a better resolution when compared to Z310. Parts coming out of
Z510 have a greater initial strength. If given sufficient time
to cure parts printed in Z310 will also achieve same strength.
But because of the grater initial strength it is advisable to
print fragile and thin parts in 510 to avoid breakage Z510 -
$3.50 per cubic inch Z310 - $3.00 per cubic inch First, the 3D
Printer spreads a thin layer of powder. Second, an ink-jet print
head prints a binder in the cross-section of the part being
created. The build
