King Tutankhamun's Funeral Mask

thingiverse

An Egyptian Pharaoh of the 18th dynasty, King Tutankhamun is known as the great child king, having assumed the throne of Egypt at around the age of 9 or 10. He died young, presumably around the age of 18, but his legend has lived on. This model is of the funeral mask he was found wearing when his tomb was discovered by Howard Carter in 1925. It is one of most well known artifacts to have come out of Ancient Egypt. Print Settings Printer: Kossel Rafts: Yes Supports: Yes Resolution: 0.2mm Infill: 75% Notes: Printed initially using Solutech PLA Real Gold, but it tends to get stuck up in the nozzle so after the print got to 20% completion I aborted and printed using Hatchbox PLA Yellow, it printed with absolutely no problems at 45% original scale. How I Designed This Sketchup I found a model that was posted online to the Trimble 3D warehouse by 'Brundiseinsis' back in 2012 (https://3dwarehouse.sketchup.com/model.html id=8c8df1fa386504db6dab6933c92047a5). I used this model as the basis for my work. I downloaded it and put it into Sketchup Make. Once there I looked the model over and made necessary changes that would cause it to be easier to print ultimately. I looked for small or incomplete features that could be improved on or removed, overlapping polygons, etc. Once I was satisfied with the new model I exported it to an STL file. Sketchup View, Original Model NetFabb Pro Once I had the STL file created through Sketchup I put it into NetFabb. Generally the STL files created by Sketchup have a lot of errors in them that need fixed. I ran a customized fix on the model, and noticed for some reason it had flipped all the polygons backwards so I had to flip all of them to the correct orientation. Once I had this step completed I checked to be sure there were few errors and with that taken care of I exported the newly repaired file into a new STL. NetFabb View Meshmixer With the STL file I created through NetFabb, I opened Meshmixer for further editing as it has some features that I find easier to use through it than other programs. I cut the back side of the model to make it flat and therefore easier to print. I then solidified it to the maximum mesh density and solid accuracy. This makes the model rather large but this is necessary in order for it to work initially, reducing the number of polygons can always be sculpted later. Once I was satisfied with the model I exported it to a new STL file. Meshmixer View Simplify3D Using the Simplify 3D software I scaled the model I exported out of Meshmixer down to 45% so I could print a version of it quickly. I sliced the model and checked everything to be sure that there would be no major issues in printing. There were none that I could immediately notice so I printed directly from Simplify3D. Simplify3D View Project: Archeology and 3D Printing Objectives -Learn more about 3D Printing and Scanning technology -Discover how 3D Printing and Scanning assists Archeologists Audience This project is designed for grades 3-8, but can be enjoyed by anyone wanting to learn about the ways 3D printing and scanning can help the archeological field. Preparation -Students should have access to a computer with either internet access so they can log into a free TinkerCAD account, or a computer that is running other software (such as meshmixer, meshlab, etc.) that can open .STL file types. -The "King Tut Funeral Mask" Model should be downloaded onto the students computers. -Computer mice for each computer is recommended -The instructor should be comfortable showing the students how to navigate the 3D space around the model in the program they choose to use for looking over the King Tut Funeral Mask model. -For the bonus step, the students will require a mobile phone, iPod, iPad or some other smart mobile device. Step 1: Learning about Archeology Have the students learn about Archeology with a particular emphasis on its focus on the study of artifacts to learn about ancient history. Explain that often times artifacts can be fragile and difficult to handle, especially if they are very old and depending on the materials they are made of. Further, the less most artifacts can be handled, the better. Other times, artifacts have to be left where they are out of respect for the people who created them. In every case, there are times when being able to properly study and handle ancient artifacts is difficult. 3D printing and scanning technologies assist in this. Step 2: Learning about 3D Scanning Watch the Youtube Video "MakerBot Digitizer Desktop 3D Scanner" This video will teach a little bit about how 3D scanning works. Instruct students that this is a method Archeologists can use to get 3D computer models of artifacts from the actual artifacts themselves. 3D scanning does not harm the objects, and with some technologies the artifact never has to be moved from the site it was found at. 3D scanning can render models very accurately depending on the technology used, even mapping the actual colors and textures. Step 3: Examining a model Instruct students to open the model of King Tut's Funeral Mask on their computers. Teach them how to navigate the 3D space around the model so they can explore the model more fully. If a 3D print of the mask is available, hand it around so the students can handle it. Have the students take a closer look at certain features of the model, such as the cobra and vulture on top of the headpiece. explain that while it would be impossible for the students to be able to actually handle or view the real funeral mask (since very few people ever get the opportunity), 3D printing and scanning technology allows for models and replicas to be enjoyed by many people. It allows for study of artifacts such as King tut's funeral mask to be done without nearly as much major risk to the artifacts themselves. Step 4: Bonus Step! Using a mobile phone, download the 123D Catch application, a 3D scanning application. Provide students with an artifact and have them scan it using their mobile phones (or the phones/iPods/iPads provided to them). When the scan is finished rendering, navigate around it and see what new observations can be made using the model that were not noticed previously. 123D Catch User Guide Results At the end of this project, students should have a better understanding of how 3D printing and 3D scanning helps the archeological field of study. If the bonus step has been completed, students will have their own 3D scanned artifacts to look at. Having the knowledge of a simple, basic way to scan artifacts gives them the ability to go out and scan the world around them, increasing the number of available models to be adjusted for printing, thus preserving world artifacts for future generations to study and enjoy.
