7.2 Filling with isopropyl alcohol
Place the outer container in the base and remove the lid and inner container.
Isopropyl alcohol is stored solely in the outer container. Do not manually fill the inner container with
isopropyl alcohol. The unit will regulate when the inner container is filled during the cleaning cycle.
The amount of isopropyl alcohol that shall be loaded in the outer container is dependent on the 3D printed
parts to be cleaned during the next cleaning cycle. The outer container has two fill lines that correspond to
two possible volumes: 1.3 liters and 2.0 liters.
If the height of the parts to be cleaned is less than
70 millimeters, fill the outer container to the
1.3-liter fill line.
If the height of the parts to be cleaned is 70 millimeters or greater, fill the outer container to the 2.0-liter
fill line.
CAUTION
Take care to ensure that no isopropyl alcohol spills from the outer container at any time. Stray isopropyl
alcohol may damage the B9Clean’s electronics or surrounding materials.
FLAMMABLE
Isopropyl alcohol is highly flammable in both liquid and vapor states.
Read the safety information in Section 2.5 before handling isopropyl alcohol.
CAUTION
Failure to load the outer container with the correct amount of isopropyl alcohol based on 3D printed
part height can result in damage to the cleaned parts.
If not enough isopropyl alcohol is loaded, the parts will not be fully submerged and the top of part will not
be cleaned.
If too much isopropyl alcohol is loaded, the inner container will not completely drain of isopropyl alcohol
when the cleaning cycle ends. The 3D printed parts may then be left to soak in the undrained isopropyl
alcohol, potentially weakening the cured resin of the parts.
NOTE
The isopropyl alcohol in the outer container can be used for multiple cleaning cycles, but the cleansing
effectiveness of a reused batch of isopropyl alcohol may decrease with each cleaning cycle it is used
depending upon material used and part geometry. Refill the isopropyl alcohol before the cleaning result
is no longer sufficient.
Note
Never install both drain plugs during operation.

7.3 Positioning the inner container drain plug.
The back of the inner container has two drain holes. The
B9Clean’s drain plug shall be snugly inserted into one of the two
holes before starting the cleaning cycle.
If the height of the part to be cleaned is less than
70 millimeters place the plug in the inner container’s top hole.
If the height of the parts to be cleaned is 70 millimeters or
greater, place the plug in the inner container’s bottom hole.
Part height less than 70 millimeters (mm)
Outer container filled to 1.3 liters
Inner container with drain plug in top hole

7.4 Placing the parts in the inner container
3D printed parts made of cured resin may be cleaned by placing
the parts in the inner container. Parts can be cleaned while still
attached to the Build Table or while resting in the part tray.
If any parts to be cleaned are still attached to the Build Table,
ensure that the hanging arm is secured to the lid and the Build
Table is snugly tightened to the hanging arm. Use the regular
hanging arm if the height of the parts is 70 millimeters or
greater. Use the extended hanging arm if the height of the parts
is less than
70 millimeters.
If any part to be cleaned is not attached to the Build Table, this
part shall rest in the part tray.
If all parts to be cleaned are still attached to the Build Table, the
part tray shall be removed.
Part height 70 millimeters (mm) or greater
Outer container filled to 2.0 liters
Inner container with drain plug in bottom hole

CAUTION
Only 3D printed parts made of cured resin shall be washed in the B9Clean. Cleaning anything that is not
a resin-based, 3D printed part will void the warranty.

7.5 Configuring the cleaning cycle settings
The Start/Stop button (A) starts or stops a cleaning cycle and is
located on the right side of the control interface. A cleaning cycle
is characterized by the 3D printed parts in the inner container
being submerged in isopropyl alcohol that is stirred at a specified
speed for a specified duration.
The duration of the cleaning cycle is measured in minutes and
controlled by the top set of buttons and indicator lights (B) on
the left side of the control interface.
The speed at which the isopropyl alcohol is stirred is controlled
by the bottom set of buttons and indicator lights (C) on the left
side of the control interface.
Use the buttons on either side of the duration and speed
indicator lights to configure the cleaning cycle settings as desired.
7.6 Overview of starting, stopping or adjusting the cleaning
cycle.
Before starting the cleaning cycle, ensure the following
conditions are met.
The outer container, inner container, inner container plug,
hanging arm, Build Table, and lid are all secured in their proper
positions.
The isopropyl alcohol fill level, inner container plug, and hanging
arm are correct for the height of the 3D printed parts to be
cleaned.
The magnetic stirring bar is placed in the bottom of the inner
container.
The part tray is inside the inner container only if any one of the
3D printed parts to be cleaned is not attached to the Build Table.
The control interface’s indicator lights show the desired settings.
Press the Start/Stop button to begin the cleaning cycle. The
cleaning cycle will run using the duration and spin speed set on
the control interface, reversing the direction of the spin every
minute. Cleaning process timer count down and stirrer operation
starts after filling of internal container.
To alter the duration or spin speed while the cleaning cycle is in
progress, change the desired settings on the control interface.
A
B
C

To end the cleaning cycle immediately without waiting for the
duration to pass, press the Start/Stop button.
NOTE
Upon starting the cleaning cycle, the unit will pump isopropyl alcohol from the outer container up into
the inner container to submerge the loaded 3D printed parts.
7.7 Starting the Cleaning Cycle
NOTE Isopropyl alcohol should be periodically exchanged. Resin color discoloration can discolor
prints.
7.7.1 After the printer has finished printing, remove the build table and DuraVat from the printer.
Confirm that the B9Clean outer container is filled with isopropyl alcohol to the level which
corresponds to the print height requirement. If the isopropyl alcohol is discolored from use, replace
the Isopropanol alcohol.
7.7.2 Place the Build Table into the B9Clean Build Table Hanger and secure with the lock knob and
place the lid into the B9Clean chamber.
7.7.3 Select the desired number of minutes for clean. Some prints may require more than one
wash. Do not continuously wash a part for more than 10 minutes, as continuous and prolonged
submersion in isopropyl can damage the print.

7.7.5 Remove the B9Clean lid and build table. No LED’s will be flashing when the operation has
stopped.
7.7.6 Blow dry the print directly after the wash has ended to prevent the isopropyl from drying
onto the print. Consider flammability of isopropanol vapors – execute drying of prints under a
hood. See chapt. 2.5 for details about personal protective measures (e.g. wearing gloves, eyewear,
etc.).
7.7.7 Inspect fine details to assure all liquid resin has been removed. Run the print through another
wash cycle or use the spray bottle with isopropyl alcohol to remove any remaining liquid resin.
NOTE

Some geometries will prevent the isopropyl from reaching all the liquid resin. These geometries
will hold the air that gets trapped when the isopropyl rises to the print. To completely clean the
print, remove the print from the Build Table and place it on the basket in the B9Clean and start
another wash cycle.
7.7.8 Ensure the printed part is dry and free of surface resin. It is recommended to use compressed
air to dry pieces prior to Curing if necessary.
7.8 B9Clean Cleaning Procedure
7.8.1 Unplug the barrel jack from the back of the unit.
7.8.2 Remove container assembly from the base.
7.8.3 Inspect base for any resin. Clean with a cloth and isopropyl alcohol while observing personal
protective measures (see chapt. 2.5).
7.8.4 Remove Lid and Inner Assembly container and set aside.
7.8.5 Remove all Isopropanol alcohol from the container.
7.8.6 Clean the inner and outer container surfaces with a clean cloth and isopropanol alcohol.
7.8.7 Inspect inner container bottom gasket to assure it is not damaged, replace if necessary.
7.8.8 Do not discard the stir bar and the drain plugs.
8 Safety
8.1 Isopropyl Alcohol Draining
To ensure that the 3D printed parts loaded in the B9Clean do not soak in isopropyl alcohol longer than the
specified cleaning cycle duration, the unit will automatically drain the inner container of isopropyl alcohol
in the following situations.
• A cleaning cycle completes
• The Start/Stop button is pressed during a cleaning cycle
• The B9Clean loses power
8.2 Isopropyl Alcohol Containment
When a cleaning cycle is not in progress, all isopropyl alcohol loaded in the B9Clean is stored in the outer
container. The inner container creates a seal when placed inside the outer container, isolating the
isopropyl alcohol from outside interference or contamination.
DO NOT USE Acetone in the B9Clean. Acetone will rapidly destroy acrylic material of containers and
pump. Warranty is void with even single use of Acetone.
FLAMMABLE
Though the B9Clean’s design reduces risk by separating the isopropyl alcohol in the outer container,
isopropyl alcohol is still highly flammable in both liquid and vapor states.
Read the safety information in Section 2.5 before handling isopropyl alcohol.
9 Maintenance, Care and Cleaning
9.1.1 Unit Cleaning
The components of the unit that come into contact with isopropyl alcohol can be cleaned with water to
remove uncured resin residue.
NOTE
Ensure that all water completely dries before refilling container and operating the B9Clean.

9.1.2 Build Table Cleaning
Remove the Build Table from the hanging arm before attempting to remove a 3D printed part from the
Build Table.
NOTE
Do not use metal scrapers or metal tools which can scratch the Build Table to remove a 3D printed part.
9.2 Isopropyl Alcohol
9.2.1 Replacement
The isopropyl alcohol in the outer container can be used for multiple cleaning cycles, but the cleansing
effectiveness of a reused batch of isopropyl alcohol will decrease with each cleaning cycle it is used
depending upon the resin used and part geometry. It is solely at the discretion of the operator to
determine when the isopropyl alcohol is to be changed.
9.2.2 Disposal
Isopropyl alcohol is classified as a hazardous waste in many countries and may require special disposal.
Contact the organization responsible for your local hazardous materials regulations for more information.
9.3 Non-Repairable Items
There are no replaceable electronic parts or replaceable wear parts on the B9Clean. All parts are rated for
