MLK LIBRARY (what the guy said in his presentation)

[The guy was James Kite – JH]

using the MLK system:

–> 20 day waiting period

–> STL files submitted to their online webform ( http://dclibrary.org/node/36592) have to be 12mb (can be larger if submitted in person with a usb)

–> up to their discretion to not print things if deemed inappropriate

–> machines they have: makerbot replicator 2 and cube x 10

–> maker bot replicator 2 scale limitations= 11.2 wide x 6.0 deep x 6.1 tall

–> cube x = roughly a 10-inch cube

things to consider:

–> can experiment/tamper with infill percentage, temperature that the machine prints at, print speed, etc

–> Z-GAP: distance between the print plate and the extruder (high z gap = more space between layers)

–> “INFILL PERCENTAGE” aka how dense is the filling material inside your object 0%= hollow ( if not hollow, the structure created inside is either diagonals or a honeycomb pattern)

–> RESOLUTION= layer thickness (standard is .25mm– the more detail per layer, the more possible “imperfections”, with a lower resolution you loose detail, but that results in an overall “smoother” finish.)

–> finished products can be altered in hot water or a deluded acetone bath

–> they use “makerware” to view/ alter  STL files for printing on the makerbot

–> “make it now” fx can result in interesting deformations

–> OVERHANG: objects w/ a lot of overhang can result in interesting deformations.  the machine can adapt to about a 45 degree increase per level without sagging.  there is an “auto support” fx on the software that adds a bit of material to help maintain the structure of the piece, but this can be turned off.
