Understanding Acrylic and Laser Cutting
Acrylic, also known as plexiglass, is a transparent thermoplastic that is lightweight and shatter-resistant. It's an excellent material for laser cutting because it melts rather than burns, producing clean edges without discoloration.
Types of Acrylic:
-
Cast Acrylic: Ideal for engraving and has a clearer edge when cut.
-
Extruded Acrylic: Cheaper and consistent in thickness, but doesn't engrave as well as cast acrylic.
Tools and Materials Needed
Before starting your project, gather the necessary tools and materials:
- Monport 80W CO2 Laser Engraver & Cutter (28" x 20") with Autofocus and Bracket
- Acrylic sheets
- Design software (e.g., Adobe Illustrator, CorelDRAW, Inkscape)
- Laser safety goggles
- Masking tape
- Ventilation system
Designing Your Acrylic Globe
Creating a globe from acrylic requires precise design work. Here's how to get started:
-
Choose a Design Software: Use software like Adobe Illustrator or CorelDRAW to create your design. For a globe, you'll need to create a map with intricate details.
-
Set Up Your Design: Import a world map into your design software. Simplify the design by removing unnecessary details, focusing on the main outlines.
-
Divide the Globe: Split the map into segments that can be assembled into a 3D globe. Ensure each piece fits perfectly with the others.
Cutting the Acrylic
With your design ready, it's time to cut the acrylic. Follow these steps:
-
Prepare the Laser Cutter: Turn on the Monport 80W CO2 Laser Engraver & Cutter. Ensure the autofocus feature is enabled for precise cutting.
-
Load the Design: Upload your design to the laser cutter’s software. Adjust the settings for acrylic—typically, an 80W laser works well with speeds around 10-20 mm/s and power at 60-80%.
-
Place the Acrylic Sheet: Position the acrylic sheet on the laser cutter bed. Secure it with masking tape to prevent movement.
-
Start Cutting: Begin the cutting process. Monitor the cut to ensure the acrylic does not overheat or shift.
Assembling the Acrylic Globe
Once all pieces are cut, assemble the globe:
-
Check Fit: Ensure all pieces fit together without gaps.
-
Glue Pieces: Use acrylic glue to assemble the globe. Apply the glue sparingly to avoid excess seepage.
-
Drying Time: Allow the glue to dry completely before handling the globe.
