Printer Startup and Demo Build

Power on the System

Your 3D Systems certified installer should have powered on your system for you. However, if the system or any of its components have unexpectedly shut down, or if you have shut them down, this section describes how to start up the system's components.

NOTE: Do not change the Modular network connections that your 3D Systems installer set up for you. If you must change them, contact 3D Systems Service to ensure this is done properly.

Power on Controller

  1. The power button is located just above the power inlet. Flip this to the I position.
  2. Give the system a few moments to boot up. The Controller's touch screen will eventually bring up the Modular GUI (graphical user interface).
  3. This does not power on the Printers.

Install Resin Tray

If you have not read the Resin Tray Guidelines, please read them before handling the resin tray.

Each Printer comes with one resin tray. This section will demonstrate how to properly install the resin tray and tension it. This section assumes that your 3D Systems installer has already installed your first resin tray; and you are replacing it with another.

  1. Disable the Printer so that it will not receive any new jobs until you re-enable it. You may do this in one of two ways:
    1. Go to the Status tab and expand the Printer Info Card on the Printer on which you wish to replace the bottle. Tap the Enable switch, and then tap Disable on the confirmation screen.
      disable-print-module.jpgdisable-print-module-confirm.jpg
    2. On the Printer, tap the gui-power-btn.jpg button on the touch screen. This will change the unit from "ready to print" to "confirm as ready," as in the screens below.
      local-gui-ready-to-print-08132018.jpglocal-gui-mark-ready-active08132018.jpg
  1. It is recommended to only add/remove tension with the upper-build-chamber door closed. To untension the resin tray, open the lower-chamber door and push the tension toggle button.

Personal Injury Warning: Failure to avoid the pneumatic tension arms may result in personal injury. Avoid the tension arm areas at all times.

  1. Close the lower-chamber door and enable the Printer, using the same method you used in Step 1, above:

    NOTE: The printer must be both "enabled" on the Controller screen and "marked as ready" on the printer screen in order to receive a print job.

    1. Go to the Settings screen > Printer Info Card for the Printer you wish to re-enable. Tap the Enable switch, and then tap Enable on the confirmation screen.
      re-enable-print-module.jpgre-enable-confirm.jpg
    2. Ensure that a print platform is installed and, on the Printer, tap the active-checkbox.jpg icon on the touch screen. This will change the unit from "confirm as ready" to "ready to print," as in the screens below.
      mark-as-ready-active.jpglocal-gui-ready-to-print-08132018.jpg
  2. The new resin tray is now ready to be filled with resin. Please see the section Fill Resin Tray with Material for more information.

Install Print Platform

Always wear 100% nitrile gloves when handling the print Platform.

CAUTION: Do not leave upper-build-chamber door open for an extended time. Leaving this open will allow light to cure the material inside the resin tray and will also allow dust/contaminates in.

 

In between builds, the Printer will prompt you to install a new, clean print platform. This section describes how to properly install a print platform.

  1. If there is a platform with a part on it currently in the machine: remove it, wearing nitrile gloves, according to the section Remove Print Platform in the Post-Processing Guide. Hold a drip tray underneath the part to catch any resin dripping off the part.
finished-part-offload.jpg
  1. Verify the platform has been properly cleaned and is not visibly warped. A properly cleaned print platform will not have any residual print material or contaminants of any kind present. Special attention should be paid to the print surface (1), and elevator guides (2).
  2. Also make sure the elevator is at its upper limit, or offload, position before installing the platform. The elevator should have moved to this position after the previous job. If it did not, cease printing on the Printer and contact 3D Systems Service.
print-surface-and-elevator-guides.jpg
  1. Install the print platform onto the elevator arms, convex side down, as seen at the right. The triangular groove on each print-platform elevator guide lines up with the cone-shaped pin on each elevator arm. Ensure the print platform is fully seated and level. Magnets will secure the platform in position. If you feel there is an issue with how the print platform is sitting on the elevator arms, and you have already tested the platform's level, do not print on the printer. Contact 3D Systems Service.

Install Resin Bottle

CAUTION: Ensure you are installing the same resin you used previously on the Printer. Residual resin from previous bottles is still in the MDM tubing and will form a bad resin mixture if mixed with a different resin type. Please see the section Material Changeover for information on how to use a different resin in the Printer.

WEAR 100% nitrile gloves throughout this procedure.

CAUTION: Do not pour resin from a new bottle into an old bottle. The printer keeps track of bottle resin level by how much resin has been pumped through the MCO tubing for that bottle. If more resin is added to this old bottle, the pump counts will not reset and the printer will believe the bottle to be empty.

 

  1. Open the lower-print-chamber door and pull the MDM toward you. There are hard stops built into the slides to keep the MDM from coming completely out.
open-mdm.gif
  1. If an empty bottle is present, tighten the top cap and press the eject button next to the bottle chute to eject it. Remove and dispose of the bottle according to all government regulations. Immediately place the rubber cap over the bottom valve, or hold a paper towel under the bottom of the bottle, to catch any resin drips.

eject-bottle-anim.gif
  1. Your new bottle must be premixed before being installed in a Printer. Ensure you have done so, as per the section Premix Resin Before Bottle Installation. Remove the red Valve Cap, and KEEP the cap in storage. You will need to re-cap the valve anytime it is stored outside the machine with resin inside.
  1. If there is no label currently on your MCO tubing, remove the MCO tubing label from your new resin bottle's box. Place the label on your MCO tube in a position where it will not interfere with the tube fitting into any machine fixture. If you are using a different resin than the label on your current tubing indicates, stop this procedure and perform a Material Changeover. The easiest way to get at the tubing is to reach behind the open MDM and pull the tubing up toward you.
tube-behind-mdm.jpg
  1. Carrying the new bottle by its handle, slide the bottle down the chute in the orientation shown at the right. The Bottle Key should be on the left and fit in the key slot (see below). Ensure the bottle is fully seated by pushing down on it until you hear it click into place.

  1. Remove the cap from the top of the bottle and take the following steps to ventilate the bottle:
    1. Grab the foil seal by the pull-tab on top.
    2. Pull on the tab from the edge of the seal, as seen at the right. Peel the seal off slowly, going down the same axis as the pull tab. Pulling straight up on the tab (below, left), or pulling along the axis perpendicular to the pull tab, can make this task more difficult and can even break the tab.

  1. Recap the bottle and tighten the cap finger-tight. Then loosen the cap by a quarter turn to allow for ventilation.

CAUTION: DO NOT FORGET TO DO THIS STEP. THE SUCTION OF THE RESIN PUMP WILL CAUSE THE BOTTLE TO COLLAPSE IF IT IS NOT VENTILATED, WHICHCAN SPILL RESIN INSIDE THE MACHINE AND CAUSE MACHINE ERRORS. THIS SITUATION WOULD REQUIRE YOU TO CEASE PRINTING AND TO HAVE A 3D SYSTEMS SERVICE CALL TO COMPLETELY CLEAN THE MACHINE.

  1. Push the MDM back until it hits its rear limit.
close-mdm.gif
  1. Ensure that the lower-print-chamber door fully closes.
  2. Your Printer is now ready to pump resin from the new bottle.
  3. Be sure to repeat this procedure anytime a resin bottle becomes empty. This will help ensure that your Printer experiences the least amount of downtime as possible.
  4. If you are filling the resin tray from a completely empty state, please see the section Fill Resin Tray from Empty for more information.

Add a Job to the Print Queue

You should have prepared your build file in 3D Sprint. For assistance in this, please refer to 3D Sprint Help and Figure 4 Modular Best Practices.

  1. On the Controller, navigate to the Queue tab. Tap the + button to begin the Add Job wizard.
add-queue-tap-+-btn.jpg
  1. The Add Job wizard will pop up. Insert your USB device into the open slot on the Controller and tap Select File.
add-queue-select-file.jpg
  1. On the next screen, tap the file(s) you wish to add to the queue and tap Add.

TIP: Tap a selected file again to deselect it.

add-queue-add-files.jpg
  1. You will see a file-upload screen.
add-queue-upload-screen.jpg
  1. Once the first build-file upload completes, you will start to see screens like the one at the right for each build file uploaded. If desired, fill out a Description (1) for your print job(s). You are required to select a Module (2) to which to send the print job. All other fields are read-only. Auto is selected by default; but you can tap the dropdown menu to see a list of all Printers on your network. Select one of the units under the heading MODULES WITH SAME MATERIAL. Please see the section Job Queue Assignment for a full explanation of Auto and Manual print queue assignment.

CAUTION: Selecting a Printer from under the heading, "MODULES WITH OTHER MATERIALS," is not advised. The material (resin) selected for the job in 3D Sprint drives the creation of supporting architecture and other printer settings that are optimized for that resin. Printing a job intended for one resin with a different resin strongly risks a failed build and, thus, wasted resin.

add-queue-select-printer.jpg
  1. Once you have filled out all the screens from Step 5, the Add Job wizard will close and send you back to the Queue tab. Whether you chose Auto or Manual job assignment, your print job(s) will appear in one of two sections of the Queue:
    1. Active Print Jobs - If the assigned Printer IS ready to print, your job will appear here. The print job will begin on the assigned unit.
    2. Pending Print Jobs - If the assigned Printer is NOT ready to print, your job will appear here. Within this section, you may tap on a print job to select it and move it throughout the print queue using the control buttons (c) at the top of the screen.
