of Warm working
The advantages
over cold working are: 1) forces and
power are higher,2) more intricate
work geometries possible, and 3)
need for annealing may be reduced
.or eliminated
T
F

A Titanium part built by Selective Laser Melting (SLM) has a height of 95mm. Estimate the total build
time for the part in hours and minutes (excluding set-up and clean-up processes) if each layer is 50 µm thick;
the laser scanning time per layer is an average of 43 seconds; the powder recoating time for each layer is 30
seconds; and every 5th layer is scanned twice by the laser for in-situ heat treatment.
1) What types of products are made using a
spider-mandrel die? Why can lubricants
not be used in spider-mandrel extrusion?
2) Make a survey of various sports
equipment and identify the components
made of composite materials. Explain the
reason for and the advantages of using
composites in these specific applications.
