In the December of 2016, the Monmouth College Chemistry Department purchased a Full Spectrum H-Series 5th Generation 45W CO2 laser engraver/cutter. This instrument was purchased, in part, in anticipation of the 2017 MACTLAC meeting where Lon Porter of Wabash College will lead a breakout session on "Fabricating Applications in Chemistry" including 3D printing and laser engraving/etching/cutting. This new instrument will be installed in CSB 373 (Physical Chemistry lab). Dec 2016.
Update (Nov, 2017)
As noted above, the laser engraver/cutter was successfully demonstrated at the 65th Annual MACTLAC conference (Oct 13-14, 2017) as a part of Lon Porter's 3d fabrication workshop". This demonstration was viewed by participants as highly unique and has many applications in the sciences. At this time, the laser has well accepted by our MC students and many of them have been using it to assist with aspects of their research projects. The laser was used in the spring of 2017 (in Chem 322 lab) to explore the fabrication of microfluidic channels. In Sept, 2017, the ventilation system was tied into the "house" fume hood exhaust. In June 2017, the laser was used to cut a Class of 2017 "stamp" that was used by facilities management to emboss a new concrete pad located near the sand vollyball court. In the early spring of 2017, the laser was used to make personalized "test tube rack/pen holders" for high school guidance counselors, as requested by our Admissions Office. Additionally, in March 2017, the laser was demonstrated as a part of the ACS Chemistry Olympiad (High School students).

- Most chemistry departments have a "laser." Although this is not a standard laser that is used to do spectroscopy, we can use this as a VERY interesting example of a laser to discuss the "Light Amplification by Stimulated Emission of Radiation" and other aspects like lenses material (ZnSe).

File Formats
When using the laser engraver/cutter, you will be working in either "raster" or "vector" mode. You can do both ("raster, then vector" mode) with a single click but this is slightly more advanced. Raster mode is ~equivalent to engraving and vector mode is ~equivalent to cutting. In all cases so far, it has been possible to raster any graphic that can be displayed on the computer screen. Since the Full Spectrum laser acts as a printer, we can say that the laser can raster any image from any program (WORD, InkScape, PowerPoint, etc). This is not the case for cutting or "vector" mode. When in vector mode, the laser follows the outline of the image (and moves much slower) to cut the material. In many cases, when an image is "printed", the raster representation in the RetnaEngrave software looks great, but the vector representation shows only the "box" outline of the image and not the edges needed to vector cut. This issue lies in the file format of the image sent to the printer.
