12 Maintenance and Care12.1 Cleaning

12.1.1 Cleaning the Printer

Clean the cara Print 4.0 using the provided microfiber cloth. Microfiber cloth can be usedto clean accessible components and surfaces in the Build Chamber and on the exterior ofthe printer.

NOTE

· Always use separate cloths for interior and exterior cleaning. A damp, solvent-freemicrofiber cloth shall be used.

· Do NOT use solvents to clean the cara Print 4.0. The cara Print 4.0 and print vats neednot be disinfected.

· For cleaning the touchscreen, always use a new, clean cloth. Contamination of thetouchscreen with material may damage the device.

· Use cloth towels to clean up large spills inside the printer. The use of paper towelswill introduce dust contaminants into the printer and may scratch critical glasssurfaces.



12.1.2 General Vat Cleaning

The vat and material held in the vat shall be inspected by the operator after every use. Cured material either attached to the aperture or suspended in the liquid materialMUST be removed prior to beginning a print.

NOTE

Failure to remove cured material will cause damage to the vat.

To remove cured material that is adhered to the aperture, drain the liquid materialthrough the provided filter into a clean bottle. Clean the excess liquid material with aclean cloth. Place the edge of a Plastic Blade supplied in the accessory kit gently on theaperture of the vat near an easily accessible edge of the cured material that is adheredto the aperture. Carefully and gently slide the edge of the Plastic Blade under the edge ofthe cured material. Once the blade is under the edge, pinch the material to the edge ofthe blade with the tip of your finger and pull the blade away from the aperture to gentlyseparate the cured material from the aperture. Use extreme caution and care whenremoving cured material from the aperture.

NOTE

· Do not scratch the aperture surface.

· Do not use any tools to remove cured material from the aperture.

The vat should be cleaned frequently. If material is present in the vat, pour the materialthrough the Material Strainer and Funnel into a clean bottle. Wipe excess material out ofthe vat with a clean towel. Do not wipe the glass aperture of the vat with disposabletowel. Clean aperture with a clean microfiber cloth dampened with isopropyl.

CAUTION

Wear protective gloves when using Isopropyl alcohol.

41Maintenance and Care


12.1.3 Print Table Cleaning

NOTE

Remove Print Table from Printer print chamber for cleaning.

CAUTION

Wear protective gloves when using Isopropyl alcohol.

Print Table shall be cleaned after each print. Clean all cured and uncured material fromthe Print Table. Use of Isopropyl alcohol is acceptable to aid in cleaning Print Table. Useonly plastic razor blades or plastic scrapers when cleaning Print Table.

NOTE

Do not use metal scrapers or metal tools to clean Print Table.

12.2 Maintenance

12.2.1 Air Filters

Clean or replace air filters on the back of the cara Print 4.0 every 3 months. Clean the airfilter by blowing it out with clean, oil-free compressed air away from the cara Print 4.0 ina well ventilated area.

NOTE

Carefully remove filters so the captured dust is not disturbed.

12.2.2 Vat Replacement

Replace the Vat when:

· Aperture contacting the print material becomes damaged.

· Seal around aperture leaks.

· Flanges that align the vat in its proper position in the print chamber become damagedor worn.

· Vat material reservoir becomes damaged, causing leaks.

12.3 Wearing Parts

There are no replaceable electronic parts or replaceable wear parts except the vat on thecara Print 4.0. All parts are rated for long life. The cara Print 4.0 is designed for anestimated operation time of 20,000 hours of intended use. Items in need of replacementmust be replaced by Kulzer service staff only.



13 Work Flow for Printing

NOTE

Any printed 3D dental object must be post cured with an appropriate post-curing device.For Kulzer liquids we strictly recommend to use Hilite® power 3D device.

It is mandatory to observe and follow material application instructions for post curingprocess completely, e.g. post-curing times, positioning, max. temperature, light intensity& spectrum.

Instruction for use of post curing devices must be observed in parallel. Kulzer will notbecome liable for incomplete or wrong production process accompany 3D printing.

17 Tips and Tricks

· Do not select “Factory Reset” unless necessary. Saved files, material specifications andprint history may be deleted.

· In general, do not orient critical fit models vertically or horizontally in cara Print CAMPrint Editor. Orient as symmetrically as possible at an angle between 30 and 60degrees.

· Orient models so the non-critical features face the Print Table.

· Attach supports to non-critical features when possible.

· Use the cara Print CAM Print Editor “Help” tab for useful information.
