An orthogonal experiment is a statistical technique that allows you to efficiently evaluate the impact of multiple factors and their varying levels simultaneously. The analysis of orthogonal experiments provides information on the effect of factors on the tested objective and the relationship between factors. In this paper we presented a demonstration of orthogonal experiment using a study on the type of resin, the resolution of the printer, the width of the channel, and the height of the channel on the chance of success of Channel Thoroughness Test for a long narrow channel at a length of 8.5 mm as an example. The result showed that we can analyze the determining factor(s) among all the factors studied on the objective; analyze quantitatively of extend of effect by linearization; study the relationship between factors by constructing 3D tables. Through this experiment, we have shown the importance of conducting a complete and thorough orthogonal experiment. It sets up a model for all future orthogonal experiments.

Description of the data and file structure

The data are mainly images of the printed device. For any further inquiries, please contact me at xiaoleinie@gmail.com.

The .stl files are the sliced file of the 3D print used to import to 3D printers. As an orthogonal experiment, there are 4 factors in this experiment. they are type of resin, resolution of printer, width of channel and height of channel. All the .stl files are named by the width and height of the channel, for example, 0.3 x 0.25.stl means it is the file used for 3D printing of all channels at the width of 0.3 mm and height of 0.25 mm. Since the printers used in this experiment are both ASIGA printer, and when we do 3D printing work, the type of resin is not decided by software, instead it is decided by the material used. Therefore for all type of resin, and both resolution of printer, as long as the channel width is 0.3 mm, height is 0.25, it is printed according to the 0.3 x 0.25 .stl file. The same nomenclature is used for all the rest .stl file.

For the images, it is name as "type of resin_resolution of printer_width of channelxheight of channel_ (number of trial)", for example, "HighTemp_27x_0.25x0.3_(2)" means this device is printed by HighTemp resin, using the printer of resolution 27 micrometer, the width and height of the channel are respectively 0.25 mm and 0.3 mm. And it is the 2nd trial of the same condition.

If you are able to read the .stl file, you are going to realize that the channel is designed very close to the bottom of the device. Therefore, all images are taken with the device flipped upside down. The green colour as seen on the image are from green dye. The reason why there is green dye in the channel, is because the channel has been flown with green dye diluted 100 times by DI water. The dye can only flow through if the channel is through. Therefore, you will also see some devices are empty. It is because the channel is blocked, no fluid can flow through.
