Overview
Raise3D E2 is a professional-grade, dual-extruder 3D printer designed for precision, reliability, and ease of use. It features an independent dual extruder (IDEX) system, allowing for mirror and duplication printing, increasing efficiency in production and prototyping. With a build volume of 330 x 240 x 240 mm, an enclosed chamber, and an auto bed leveling system, the E2 ensures high-quality prints across a variety of materials, including PLA, ABS, TPU, and carbon-fiber-reinforced filaments.

Reservation
Raise3D E2 must be reserved before using. The reservation is done using the Google calendar. Users will be able to reserve the equipment personally after attending the RAL lab orientation and then following the steps below to gain access to the equipment.
Video demonstration
The following videos demonstrate capabilities and the some aspects of operating the Raise3D E2 printer:Important reminders and safety
- Some parts of the printer get very hot during operation and take a while to cool down. Be careful when removing the printed parts or doing work inside the printer.
- Make sure to log the print and the amount of material used.
Designs can be made in any software capable of saving models in STL format (e.g. Onshape, AutoCad, SolidWorks, ProE, etc.). The on site computer station is meant for operating lab equipment only. Do not work on your CAD models here, your files can be brought over on a flash drive or wireless method.
Remember to set the appropriate tolerances in your STL files: tolerances should be smaller than the smallest feature in your design. Don't make tolerances much smaller than 3D printer resolution. Also, be mindful that small tolerances produce larger files.

ideaMaker is the required slicing software for using the Raise3D E2 printer in the RAL lab. It is pre-installed on the lab's computer and can also be downloaded for free for use on a personal PC. The following instructions guide you through the installation process.
Export the designed 3D models into a compatible format (e.g. stl) and open them in ideaMaker for slicing and print preparation.
Preparing for slicing
Basic toolbar tools:
- View: used to view model and navigate, selecting a model will let you know which extruder will be used for that model. By default that is always the left extruder. Note that the same camera navigation is available regardless of tool. Extruder selection is the only unique feature.
- Move: use to move the model around; can also use axis arrows on the model. Selecting the Move tool you can also Arrange all Models to fit on the build plate if possible.
- Rotate: drag rings on object or use button to lay object flat.
- Scale: change size of object; use object dimensions, scale percentage, or arrows on model.
- Free cut: separate model using a guide plane.
- Duplicate: add copies of models.
Quick orientation change:
- press shift + L to select a face on your model to lay flat to the surface;
- press shift + A to arrange all selected models on the build plate.
Slicing
Click Start Slicing to begin slicing.
ideaMaker slicing interface - Select the filament for the Left Extruder:
- for PLA select [Raise3D] PLA 1.75mm;
- for ABS select [Raise3D] ABS 1.75mm.
- Select quality template. In each template preset you can adjust:
- layer height;
- number of shells;
- infill density;
- infill print speed.
- Design model in a CAD software.
- Export model as an STL file.
Single extruder printing
Preprint check
All parts of the checklist must pass before printing.
- Tap the display to check if the printer is powered on. If the screen remains off, turn on the printer using the power switch located at the lower right back.
Check the printer to see if it has the proper filament loaded on the correct side (left by default).
Left filament holder Check that the flexible metal bed is properly aligned with the edge of the build plate (flexible bed should slide pass the flange on the build plate).
Build plate without the flexible bed. The flange is the small raise along the front edge. 
On the left is an incorrectly placed flexible bed. The bed is resting on top of the flange. On the right is shown the correct placement with the flexible bed behind the flange on the build plate. Check that the nozzle is clean.
On the left is a dirty nozzle with a glob of solidified plastic on it. On the right is a clean nozzle with no globs on it.
If at least one check does not pass, ask the superuser for assistance.
