Start by signing into an account at eiger.io
Ask a staff member for the account info.
From the Library tab select the Needle Bearing Block sample file
On the General tab on the right make sure to select the Onyx material and the Industrial Series for the Printer Types
We will be using Onyx material exclusively for this printer
Choose the orientation of your part by either selecting the face that you want face down on the print bed or by using the Manual Rotation option under the General tab
Next move to the Settings tab
You can change the layer height to obtain a desired resolution
As a reminder it will take longer to print with a smaller layer height
You can also change the units if the part looks way too big or small or the scale to get to the size you want
Next you can choose whether or not you want supports and what angle you want the supports to print at
Note that this printer cannot print very well without supports past a 45deg angle overhang
There are a couple other options under the Settings tab that have a question mark to give more information about it
I like to use the Turbo Infill and Supports when it is an option because it speeds up the print time significantly
Under the Infill tab, you can choose the different infill options
You have several different options for infill patterns
You have different infill density options depending on which infill pattern you chose
A higher fill density will take longer to print
You can also change the number of roof and floor layers as well as wall layers to strengthen your part at the cost of print time
Typically I would leave most parts at the default settings
Once you are done selecting these settings, click the Save button at the bottom of the screen
The program will now slice your part
Once it is done, you can see some details about your part on the left under Part Details like how long your print will take and how much your part will cost
Once it is done, you can see the slice preview in the XRAY section
In the internal view you can see where there are any supports in purple
This part has a little lip on the inside that requires supports
You can return to the part view by selecting PART if you want to change any settings, then click Save again to slice your new print
Once you are ready to print, select the Print button from either the Part or Internal View settings
In this view, you can move around your print on the build platform or add other sliced parts
Once you are ready:
Get staff approval first!
Set Select Printer to X7
Click Print
2. Slicing a Print with Continuous Fiber
2. Slicing a Print with Continuous Fiber
Following the first several steps as before with the same part, under the General tab select a continuous fiber for reinforcement material
For a sample part, check what the continuous fiber in the printer at the moment is, however fiberglass is preferred because it is cheaper
Under the Settings tab you will see that you can no longer change the layer height because it is defined by the reinforcement material chosen and its unchangeable layer height
You also will not be able to choose the Turbo Infill option
You will be able to edit the details of the fiber in the XRAY view.
It defaults to adding several layers at the bottom and top of the part.
In the layer view bar at the bottom you can select the sections of fiber and even edit which layers get them.
You can also create new sections at the bottom.
When you click on a section you will see it highlight a box on the right.
There are a lot of settings you can change to control where and how exactly to put the fiber.
You can even make a sketch to add it only to one part of the layer.
Fiber Fill Type
An important thing you want to choose is the way the fiber is laid inside the part, either concentric or isotropic
The following pictures describes the difference between the two
If Concentric is chosen, you will have the option of which Walls to Reinforce
In either fiber fill type, you can choose how many Concentric Fiber Rings needed
If you choose Isotropic Fiber, you will have the option for Fiber Angles
I believe the list will change the angle of the fiber for each consecutive layer to get a stronger part in multiple directions
You can create a new section of fiber by dragging along the bottom layer bar to create a section of layers.
On the top right, under the Create New Override dropdown, select Add Fiber.
Once you are happy with your settings, select Save.
Then select Print which will take you to the build plate view which will follow the same steps as before.
3. Starting a Print
3. Starting a Print
Before the print is sent to the printer
Get the purple Elmer's glue stick from the cabinet under the printer
There will already be glue on the bed
Add glue on the back, left corner, left side and in the center just where your print will be
Check to make sure the bed is clear of any debris or printed parts
Now the printer is ready for your print job
Close the clear cover and start the print
4. Removing a Print
4. Removing a Print
You should now have a successful print!
Remove the build plate from the printer and grab the spatula with the yellow handle from below the printer
Don’t use this spatula on any other printer!!
Push the build plate against something stiff that won’t move easily when pushed, I like to use the back of the Method printer (Darth Vader)
The spatula is very sharp, DO NOT PLACE YOUR HAND OR OTHER BODY PART IN FRONT OF THE SPATULA, it takes a lot of force sometimes to remove the parts and people have cut themselves removing parts
Tilt the build plate with one hand and use the other to push the spatula under the part, you may have to turn the plate around a couple of times
Once the part is removed, use the spatula to remove the purge line, purge tower, and calibration lines
Then make sure to replace the build plate , ensuring that it indexes properly into the holes and doesn't wiggle.
On the screen, indicate that you have removed the part by selecting Clear Bed
The screen should change to say Ready to Print
With your part you can do any post processing needed, for this part you can remove the supports using some needle nose pliers
Because the Onyx filament has chopped carbon fiber embedded in it, you want to avoid sanding the part because you don’t want to breathe in the carbon fiber dust
