Preparing the Fuse to Print

Ensure you are wearing a pair of nitrile gloves.

Touch the Queue tab (2nd option) on the far-left side of the Fuse touch screen.

Find and select your print. 'Select Print'.

Preprint checklist will appear. You must complete this checklist before each print. Select begin.

You can follow along with the preprint checklist similar to the way you can a dozuki for each step.

Before starting the print checklist, check maintenance checklist. Refrence Maintence Dozuki.

Touch the "Unlock Door" button on the Fuse. Open the door to access the inside of the Fuse.

If the Build Chamber is not already inserted, open the blue and black latch.

Move to the post-processing station.

Press down on this tab on top of the diagnostic cable to quick-release it.

Pull the diagnostic cable out of its socket and place into its holder on the Build Chamber.

Grab the Build Chamber by the side and carefully transfer it from the post-processing station to the Fuse by inserting it into the tracks below the print bed.

Remove the diagnostic cable from its holder on the Build Chamber and insert it into the jack on the Fuse. Close latch, close door.

Accessing the IR Sensor

Use a step-stool to access the door on the top of Fuse directly above the touch screen.

Access the IR sensor by rotating clockwise and pulling.

The IR sensor is magnetic so slight force is required to remove it.

Inspect the IR sensor for any debris such as dust or nylon powder. If debris is present, the sensor will need to be cleaned.

TIP: Rotating the sensor so that the ceiling lights reflect off of it will help identify debris.

Cleaning the IR Sensor

Push down on the prong on top of the yellow cable to remove it from the IR sensor and set aside.

Grab swab and the bottle of ethanol from the cabinet.

Apply one pump of ethanol to the swab and wipe down the mirror on the IR sensor.

Wipe with a dry swab and repeat if necessary.

After cleaning, plug the sensor back into the yellow cable.

If seated properly the butterfly on top of the IR sensor will illuminate green , and yellow/orange if incorrect. Close access door.

Ensure you put on BRAND NEW nitrile gloves or that your current gloves are FREE OF POWDER.

Touch the “Unlock Door” slide on the touch screen of the fuse. Unlock and open the Fuse door.

Loosen the screw in the front-center of the print bed, SLOWLY LOWER the tray holding the laser window.

Be careful NOT TO TOUCH THE GLASS. Remove the optical cassette.

In the cabinet, there will be a tray containing several cleaning items:

Alconox

Distilled Water

Ethanol

Woven Cloths/PEC Pads

Optical Cassete Box

Open the “Dirty" box and grab the new optical cassette.

Place the optical cassette you removed from the Fuse and in the “dirty” box.

Make sure the side of the optical cassette that DOES NOT have the blue gaskets is facing you.

Use a PEC Pad and one pump of Alconox (Labled “1”). Begin wiping the larger area glass in a criss-cross pattern. i.e. completely vertical then completely horizontal.

Use a new PEC Pad and one pump of distilled water (Labled 2). Wipe the glass in the same pattern with 2 passes.

Using a dry PEC Pad, wipe the glass dry. May take 2 dry wipes to remove water.

Use a woven cloth and one pump of ethanol '''(Labled 3). Wipe the glass in the same pattern.

If debris is on the gasket side of the optical cassette, wipe with a woven cloth and ethanol ONLY.

Hold the optical cassette up to the light and inspect for any extra debris. If debris is on the same side you just cleaned, repeat cleaning process using ethanol ONLY.

Once optical cassette is clean, replace the optical cassette tray in the Fuse. The blue gaskets should be facing UP and be sure NOT to touch the glass.

Take note of the current powder level in the hopper on the right side of the Fuse. If more powder is needed, you will add it now.

Reference Software Dozuki for needed powder quantity.

Reference post-processing Dozuki for proper powder mixing.

Grab the hopper from the post-processing station. Open the lid on top of the hopper on the Fuse.

Place the hopper containing the replacement powder on top of the hopper on the Fuse, making sure the blue handle is facing out.

Once the hoppers are secured, pull the blue knife handle to release the replacement powder.

After the majority of the powder has been released, tap the top of the hopper a few times to release any excess powder. Wait 30 seconds to let the powder settle.

Slide the knife handle closed. Remove the hopper and close the lid on top of the Fuse.

Once all items are completed, touch print on the Fuse touch screen to begin the print.

Before the Fuse prints, it will heat up to operating temperature and layer powder.
