# What is craft?
1000s of years old
Highly skilled
Only labeled “arts and crafts” after the industrial revolution
Often centered in women’s “busy” work
Sometimes entrepreneurial

# Prepare for Printing
- Create a model using any one of a number of 3D modeling packages such as Sketchup, Open SCAD,
Rhino 3d, Meshmixer, Blender, OnShape, Minecraft, SolidWorks
- Some packages reprsent 3D objects as solids, others as shells and boundaries.
- Or you can find lots of stuff in repositories, like [Thingiverse](http://www.thingiverse.com/)

- Create a model using any one of a number of 3D modeling packages such as Sketchup, Open SCAD,
Rhino 3d, Meshmixer, Blender, OnShape, Minecraft, SolidWorks
- Some packages reprsent 3D objects as solids, others as shells and boundaries.

# Some key things to know about Laser Cutting
.left-column50[
We're using a [Glowforge](https://glowforge.com/).
- It takes SVGs as input
- It can engrave, cut, etc
- We're providing plywood, 3mm thick [double check with calipers]
]
.right-column50[
Software options
- Powerpoint: Can even [merge shapes](https://www.indezine.com/products/powerpoint/learn/shapes/2016/shape-union.html). Probably best for total beginners if you have it.
- [Adobe Illustrator](https://www.adobe.com/products/illustrator.html). Best for most tasks if you have it
- [AutoCAD](https://www.autodesk.com/products/autocad/overview?term=1-YEAR&tab=subscription) (free for students). Probably overkill
- [Inkscape](https://www.autodesk.com/products/autocad/overview?term=1-YEAR&tab=subscription) (free). Best free option

# What can you do?
.left-column40[
![:img Illustration of cutting scoring and engraving first with those words and then with stars. Cutting cuts a hole; Scoring outlines something; and Engraving burns it into the wood, 70%, width](img/3dprinting/laser-Cut-Score-Engrave.png)
]
.right-column60[
Cutting: Makes a hole.
- Any line can be cut
Scoring: Doesn't cut all the way through.
- Again, any line
Engraving: Burns. Can do greyscale.
- Expand with fill
- Images. Make sure they're not too dark.

# Essential Measurements
The amount of wood removed by the laser cutter as it burns through the wood.
Should always test for each new type of wood and wood thickness
[Instructable](https://www.instructables.com/How-to-Adjust-for-Wood-Thickness-and-Kerf-on-a-Las/) on how to do this
Only an issue if you're making a box or something else that has to assemble
Use calipers to measure!
---
# Your process
.left-column50[
Measure thrice
Make an svg
Print it on paper
Cut it out and check your measurements AGAIN
]
.right-column50[
Decorate
Save to SVG
- First "expand" (if needed)
- Include mm as units
- Include images
