More than a century ago, the father and son of the glassworker Glaschka in Dresden, Germany, used stained glass to create a realistic and highly realistic imitation of plants and marine life. Today, several museums (mainly in the northeastern United States) still retain the original works of thousands of Blaschka fathers and sons. These works have been meticulously preserved and have never been moved, as each movement has the potential to cause permanent damage.
But museum curator, marine biologist and Cornell University professor Drew Harvell hope to share these beautiful works with the vast majority of people in the world who can't see them. To this end, Professor Harvell is working with Peter Fried to improve the 3D scanning of these collections. Through Fried, Stratasys distributor CADD Edge learned about the information and suggested that they use Stratasys' new multi-material full-color 3D printer J750.
In addition to full-color printing, the J750 has an extremely high resolution with a print layer thickness of up to 14 microns. The first test print was for the Blaschka work numbered B-560. The work is a 2-inch squid with a history of more than 130 years. Today, the B-560's beautiful 3D printed reproductions are extremely durable and can be easily moved and handled safely.
This initial print (not yet attempting to mimic the transparency and translucency effects) requires very little adjustment in the workflow from 3D scanning to 3D printing. Using photogrammetry and Agisoft Photoscan software, Professor Harvell and Fried obtained the VRML files for the B-560's geometry and color texture mapping. The file was imported directly into J750's new slicing software PolyJetPolyJet Studio and then printed. In addition to the need to remove the support structure, the printed work does not require post-processing such as sanding and coloring. This perfectly demonstrates the high resolution of the J750 and its excellent color reproduction.
The early success of printing the B-560 proved that the J750 is a changer in the industry game. In addition to making prototypes, the machine also protects history. Although people are increasingly interested in the 3D scanning of the precious artifacts left by the Blaschka father and son to the world, they can be truly and vividly displayed in 3D to make them truly unobstructed.
Fried said that next step they will perform a 3D scan of the B-560 with transparent and translucent effects, while also scanning more Blaschka works, including larger works like jellyfish. The J750 will be on call, because it can print a variety of transparency effects without the hassle of printing full color, let us look forward to it!
