Welcome to Ember!
This quick-start guide will help you set up Ember and start printing. This guide contains only the essentials, so most sections have a link to a more-detailed guide if you need it.
Please read all the safety warnings and instructions in Section 1 of the User Manual.
Always wear safety glasses and nitrile gloves when operating the printer or handling resin or isopropoyl alcohol. Resin is a sensitizer. Keep resin away from hands, clothes, food, or anything else that may contact bare skin.
SET UP A WORKSPACE FOR PRINTING
This workspace should have:
- A nearby electrical outlet
- A level workbench at least 3ft x 1.5ft (~1m x 0.5m)
- Access to the internet either by ethernet or WiFi
- Stable room temperature
DOWNLOAD PRINT STUDIO
INSTALL USB DRIVERS
SET UP EMBER AND FINISHING KIT
- Unbox your Ember, keeping the packaging in case you need to ship your printer at a later date
- Set up Ember on the workbench and remove the tape securing the door and the rotation plate in place
- Install the build head and resin tray, making sure the resin tray is properly seated
- Unpack the finishing kit and set it up next to the printer
CONNECT EMBER TO YOUR NETWORK
- Plug in power to your Ember
- If connecting to the internet via Ethernet, plug in your Ethernet cable
- Ember will boot up and, if connected to the internet via ethernet, will display a pairing code
- If you want to use WiFi instead of Ethernet, connect your printer via WiFi to obtain the pairing code
- Note: Make sure that your ethernet network does not require prior authorization in order to connect
- Note: Ember cannot connect to captive portal WiFi networks
PAIR WITH EMBERPRINTER.COM
Pairing your Ember with emberprinter.com allows you to monitor and manage your printer.
- Navigate to emberprinter.com in a web browser
- Log in with your username and password, or create an account
- Enter your pairing code in the field labeled Printer Code (ABCDEF)
- Enter a printer nickname
- Click Add Printer. A green dialog box will appear saying “Printer successfully registered!”
CONNECT EMBER TO PRINT STUDIO
- Open Print Studio
- Click on the printer icon in the upper left corner of the window to open the printer dialog
- Add your printer over USB or Network (find your printer’s IP address by holding down the left button on the Ember front panel for 5 seconds)
OPTIONAL: USE A RADIOMETER TO CALIBRATE IRRADIANCE
Ember’s projector is calibrated at the factory to deliver UV light at 25 milliwatts per square centimeter (mw/cm^2). However, because the PDMS window in Ember resin trays degrades with use, it’s useful to be able to determine how much light is reaching your resin with a given tray. If you have (or can procure) a radiometer that measures 405nm UV light, it’s good to get into the habit of calibrating your Ember’s irradiance periodically, and also each time you switch trays.
Click here to learn how to calibrate your projector’s irradiance with a radiometer.
If you don’t have a radiometer, you can still print an irradiance test part that will help gauge irradiance.
If you’re using a brand-new Ember with a brand-new tray, you don’t need to calibrate irradiance.
PREPARE A JOB
- Import an STL file
- Choose a resin profile by clicking the icon in the upper left corner of the screen (see above)
- Click Layout and position your part
- Click Repair and repair any issues with your STL
- Click Supports and add supports
- Click Preview to slice the model and preview the slices
- Click Print to send the job to Ember
NOTE: If you choose not to use supports, you must go back to the Layout step and click Move to Build Surface after deleting the supports, or else your model won’t attach to the build head.
START A JOB
- Fill the Ember resin tray to the Max Fill line
- Press Start on the Printer
- When prompted to calibrate the build head, loosen the build head calibration bolt and let the build head lower down under its own weight onto the PDMS layer. The build head should be flush and parallel with the PDMS and square with the right edge of the resin tray. Tighten the calibration bolt.
- Close the door and press Done
- The front panel will show the time until the print finishes
REMOVE YOUR PART FROM THE BUILD HEAD
- When the print is complete, open the door and remove the build head
- Watch out for resin dripping from the build head
- Bring the build head over to the finishing station
- Using a scraper, gently remove the part from the build head
- Scrape of any additional cured resin, making sure the build head surface is clean
FINISH YOUR PART
- Pour IPA into your two containers at your finishing station, and label them Rinse 1 and Rinse 2
- Place the part into Rinse 1 and let it soak for 5 minutes
- Place the part into Rinse 2 (not shown above) and soak for 1 minute
- Remove the part and dry it with a paper towel
- Place the part in a UV curing oven (or use a UV curing lamp) for maximum strength
- If you’re done printing parts for now, wipe any resin off the build head and clean the resin tray
