Unpack the build9
After printing, the build must be extracted from the build unit.
General advice and precautions
As the build is at a high temperature while printing, you must wait about 30 minutes before extracting the
build unit fr
om the printer. Then some further cooling time is required in order to preserve part quality.
Tips
● Wear personal protective equipment: see
Personal protective equipment on page 14.
● Unpack calmly.
● There are physical buttons with which you can raise or lower the printing platform to make the
unpacking pr
ocess more convenient.
● The sides and corners of the build chamber are colder than the center.
● If the parts are large, or the material around the parts seems very hot, leave them aside to cool
do
wn.
● If you notice that the vacuum speed slows down, try to unpack material from cooler locations or
fr
om cooled parts.
● Unpacking can be done from the build unit or from the natural cooling unit. Recycled powder
output during unpack w
orkflow can be selected from Settings > Utilities > Process Configuration
> Configure Material Output. To handle the natural cooling unit, a forklift with particular
characteristics is required. For this purpose, HP strongly recommends the Hovmand Forklift 5200.
– The Hovmand Forklift 5200 is specifically designed to support loading and unloading the natural
cooling unit
.
– The presence of at least one Hovmand Forklift 5200 per facility is strongly recommended.
– For more information on the product and to order the Hovmand Forklift 5200, consult your local
HP 3D prin
ting specialist.
– Please be aware that HP’s Limited Warranty does not cover any problems that may arise from
the use o
f non-approved third-party lifting devices.
– For more detailed information about the use of the Hovmand Forklift 5200, including an
e
xplanation of the position stops, see the user guide provided by Hovmand.
If the forklift does not fit
In some cases, the forklift may not fit into the processing-station guides.
To solve this problem, some parts from the processing-station structure should be replaced by parts
fr
om the the sheet-metal parts service kit (3FW27-67150).
