Accessible 3D Printing: Multicolor Molecular Models From Consumer-Grade, Single Filament 3D Printers
Direct linkH. Martin; E. Eisner; J. K. Klosterman – Journal of Chemical Education, 2023
3D printers have facilitated a wealth of 3D printed molecular models illustrating key structural concepts for student learning. However, general adoption of 3D printed models in the organic chemistry classroom proceeds slowly as the majority of consumer-grade 3D (fused deposition modeling (FDM) and resin) printers are inherently monochromatic,…

Peer reviewedMatthews, Kurt R.; Landmark, James D.; Stickle, Douglas F. – Journal of Chemical Education, 2004
The procedure to produce standard curve for starch concentration measurement by image analysis using a color scanner and computer for data acquisition and color analysis is described. Color analysis is performed by a Visual Basic program that measures red, green, and blue (RGB) color intensities for pixels within the scanner image.
