CAUTION 

Read the safety information in Section 2 before attempting to operate the B9Clean.

                                                                                                                                            

7.2 Turning the unit “ON” and “OFF”

The B9Clean is always on when it is plugged into a power socket. To turn the unit off, disconnect it from Mains.                                                                                                                                                  

7.3 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. 50 prints is the average amount of prints per isopropyl alcohol refill in regular use.  

                                                                                                                                                               

 

                                                                                                                                                               


                                                                                                                                                               

  Note 

Never install both drain plugs during operation.






7.4 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.


7.5 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.


                                                                                                                                                                


                                                                                                                                                                

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.

                                                                                                                                                        


                                                                                                                                                                    





7.6 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.

                                                                                                                                                                     

                                                                                                                                                                     

 


7.7 Starting 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.

 

To alter the duration or spin speed while the cleaning cycle is in progress, change the desired settings on the control interface.

 

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.

  NOTE Isopropyl alcohol should be periodically exchanged.Resin color discoloration can discolor prints.                                                                                                                  

 

7.8.1 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 Isopropyl alcohol.


7.8.2 Place the Build Table into the B9Clean Build Table Hanger and secure with the lock knob and place the lid into the B9Clean chamber.

    7.8.3 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 1 hour as         continuous and prolonged submersion in isopropyl can damage the print.


                                                                                                                                                 

7.8.4 Press the start button to begin the cleaning cycle. 

                                                                                                                                                 

7.8.5 Remove the B9Clean lid and build table. 

                                                                                                                                                 

7.8.6 Blow dry the print directly after the wash has ended to prevent the isopropyl from drying onto the print. 

                                                                                                                                                 

7.8.7 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. 

 

7.8.8 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.  

                                                                                                                                                  

7.9 B9Clean Cleaning Procedure                                                                                                                    

7.9.1 Unplug the barrel jack from the back of the unit.                                                                                                                              

7.9.2 Remove container assembly from the base.                                                                                                                                  

7.9.3 Inspect base for any resin. Clean with a cloth and isopropyl alcohol.                                                                                                                                 

7.9.4 Remove Lid and Inner Assembly container and set aside.                                                                                                                                 

7.9.5 Remove all Isopropanol alcohol from the container.                                                                                                                                 

7.9.6 Clean the inner and outer container surfaces with a clean cloth and isopropanol alcohol.                                                                                                                             

7.9.7 Inspect inner container bottom gasket to assure it is not damaged, replace if necessary.                                                                                                                                        

7.9.8 Do not discard the stir bar and the drain plugs.

 DO NOT USE Acetone in the B9Clean 

                                                                                                                                                            

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.

Though the B9Clean’s design reduces risk by sealing 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

4


During a cleaning cycle, the isopropyl alcohol in the inner container is not completely submerging the

3D printed parts.


There is not enough isopropyl alcohol loaded into the outer container.

See section 7 to determine how to set up the B9Clean based on the height of the 3D printed parts being cleaned.

The inner container drain plug is in the wrong position.

The height of 3D printed parts exceeds the maximum allowed height of 127 millimeters (5.125”).

Refrain from using the B9Clean to clean parts that exceed the maximum height allowance.


If none of the above solves the problem, contact B9Creations, LLC, support.

5

After a cleaning cycle finishes, the inner container is not completely drained of isopropyl alcohol.

There is too much isopropyl alcohol loaded into the outer container.

See section 7 to determine how to set up the B9Clean based on the height of the

3D printed parts being cleaned.


If none of the above solves the problem, contact B9Creations, LLC, support.

6

After a cleaning cycle finishes, the 3D printed parts are not completely clean of uncured resin.

The isopropyl alcohol in the outer container needs to be changed.

Properly dispose of the old isopropyl alcohol and load the outer container with a fresh batch.

The cleaning cycle duration or spin speed settings are too low.

Increase the duration and spin speed settings to find the optimal values for a particular 3D printed part.

The 3D printed parts being cleaned have too much uncured resin to be completely cleaned by a single cleaning cycle using the maximum duration and spin speed settings.

Manually wipe noticeably excess uncured resin from the 3D printed parts before attempting to clean them using the B9Clean.

Run the under-cleaned

3D printed parts through multiple cleaning cycles.

Manually increase the duration of an in-progress cleaning cycle by adding minutes to the duration after some number of minutes have passed.

The isopropyl alcohol in the inner container is not completely submerging the

3D printed parts.

See Error 4 in this table.

14 Tips

    14.1 The magnetic stirring bar must be placed in the bottom of the inner container before starting a cleaning cycle.

                                                                                                                                                                                     

If any one of the parts to be cleaned is not attached to the Build Table, the part tray must be inserted into the inner container.

If all parts to be cleaned are attached to the Build Table, the part tray must be removed.

                                                                                                                                                                                   

16.2 The duration and spin speed of a cleaning cycle can be adjusted while the cleaning cycle is in progress.

                                                                                                                                                                                     

16.3The isopropyl alcohol should be replaced with a fresh batch if the current batch appears dirty or is not cleaning parts effectively.
