The transparent window in the center creates the dead zone that unlocks the speed and quality of the Digital Light Synthesis™ process. During printing, light from the light engine in the body of the printer shines through the window and cures liquid resin to build parts. ![](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/jthZX1TadF38LWaaKod25_cassette-overview-v04-1500x.jpg) :::hint{type="danger"} The window is not a simple piece of glass, but a **highly-engineered,** **complex optical membrane. **Treat it as delicately as your own eye. ::: ::Image[]{src="https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/YjrEsMkkJqbXSXB1skK9h_l1-window-eye.png" size="70" width="1233" height="492" position="flex-start" showCaption="false"} :::hint{type="warning"} Improper maintenance or damage to the window will reduce print quality and may result in failed prints and production delays. ::: ## Product Options Cassettes are available per printer type.

The lid keeps light, dust and debris from getting to the resin stored in the cassette, keeping the resin safe for reuse. The lid is especially helpful for **oral health** customers that use one-part resins. ![](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/YO9PCqYZsH7ar5dvzQQrH_image.png "Lids on the M2 and M3 cassette") For more information about cassette lids, go to [M1/M2 Printer](docId:3ZDk7TJC-T7_JRBXI33eT) or [M3/M3 Max Printer](docId:2nxiKvTUJloOWyMApXUNL). *** # Transport ## Wear Clean Gloves Always handle all cassettes with **clean gloves** to avoid contaminating. ::Image[]{src="https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/TT6SeVZ_VjyiZkEtJSfbU_image.png" size="50" width="1280" height="1076" position="flex-start" showCaption="false"} :::hint{type="warning"} **Do not handle the underside of the cassette. **This will minimize cleaning and maintenance on the underside. ::: ## M Series Cassettes ::::VerticalSplit{layout="middle"} :::VerticalSplitItem When carrying M Series cassettes, use **both hands** and hold the cassette frame using the - Outside lip on an M1 cassette - Handles on an M2 cassette - Handles on an M3/M3 Max cassette ::: :::VerticalSplitItem ![Carrying an M2 cassette](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/i1ssXoGRcdobFPzvRbWgl_image.png "Carrying an M2 cassette") ::: :::: ![](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/z4sSJs41CLOFVdwrcvlq7_transport-handles-3cassettes01.jpg) ## L1 Cassette The L1 cassette weighs \~45 lbs\* and should be moved with the [L1 Cassette Cart](docId\:iBV6gVPWquTiQ9FUSb89_) whenever possible. *\* Legacy B1 cassettes weigh \~60 lbs* ::Image[]{src="https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/Ou_BFQDYw5p-lHxjaF7P0_image.png" size="70" width="1680" height="945" position="flex-start" caption="L1 cassette removed from printer with Cassette Cart" alt="L1 cassette removed from printer with Cassette Cart" showCaption="true"} ### Cassette Hotel When moving the cassette into one of the L1 Cassette Hotel drawers, it will be necessary to have **2 people** manually lift the unit and gently place it in the intended space.
