Introduction

Centered around the idea of additive manufacturing, as opposed to subtractive methods, 3D printing has quickly become a powerful tool for prototyping, design, and visualization and has opened up many new avenues in art, education, engineering, and applied sciences. Even as access to 3D printing facilities is quickly becoming ubiquitous across college campuses, the process of taking a mathematical idea and making it into a printable model presents a big hurdle for most mathematicians. Alongside two hands-on workshops which tackle this task, the Short Course will focus on the role of 3D printing in mathematical art, education, and visualization together with a thorough discussion of the challenges in current approaches to the technology. The main objectives of the course are to build skills and confidence with 3D modeling and to provide a springboard for future engagement with 3D printing.

The course is oriented towards a broad audience and requires an elementary background in undergraduate mathematics. Participants will be able to use their own computers and tablets for several stages of the training sessions through easily accessible software. Instructions and guides on the software will be available prior of the Short Course. Participants are also encouraged to bring their model ideas and visualizations including objects from geometry, topology, combinatorics, dynamical systems, algebra, and any other area of mathematics.

Topics and Lectures

The primary goal for the first day will be to introduce participants to 3D printing concepts and to provide a hands-on experience with printing their first model. The first two lectures, “Visualization of Mathematics with 3D Printing” and “Introduction to 3D Printing,” will showcase existing works and give a detailed dive into printing technology. The afternoon of day one will be devoted to a tutorial of printing software aimed at learning slicing, infill, supports, and model clean-up techniques, followed by a workshop where participants will collaborate to prepare a model for printing. Each group will be able to pick up their printed model at the end of the course. Day one will conclude with an Art Exhibition of works by the speakers, participants, and local artists. Participants should contact the organizers if they would like to exhibit their work.

Day two will begin with a discussion of the speakers’ experiences with “3D Printing and the Classroom” as well as an overview of projects and efforts at other institutions. This will be followed by a lecture on the “Mathematics and Challenges behind 3D Printing,” which will discuss the geometric and algorithmic aspects and constraints of current 3D printing technologies. The afternoon will begin with a lecture on “Designing a Model with Mathematics” to illustrate the process of going from a mathematical concept, to a visualization, and finally to a printable model. The tutorial for that day will focus on using different software tools and techniques for building and editing mathematically-inspired models. During the workshop, participants will get help and guidance while designing a model themselves or in groups. Several guided examples will be provided, but participants are always encouraged to be creative and work on their own ideas

The course will conclude with a Panel Discussion with speakers and outside experts. The panelists will speak on their motivations, successes, and failures in working with printing technologies and mathematical visualizations from artistic, research, and pedagogical perspectives. They will also discuss available resources, training, and objects that desperately need to be printed. The panel will include a Q&A and discussion with participants.

Lecture #5: Augmenting 3D printed objects for interactivity

3D printing is a wonderful way to illustrate mathematics. We get tangible objects. By augmenting them with additional features, we can make our pieces interactive. This talk will present a family of similar objects, with various features for interactivity. The major addition to the plastic is electronics, powered by a student-programmed Arduino. By adding effort beyond the build platform, we gain access to a world of projects for show, outreach, and teaching.

David Bachman is a professor of Mathematics at Pitzer College in Claremont, CA. He received a PhD in 1999 from the University of Texas at Austin, and has since published over 20 research articles, three books, and received two grants from the National Science Foundation. Eleven years ago, David's background in mathematics and his affinity for working with his hands converged when he began to experiment with 3D printing. Since then he has created unique two and three-dimensional pieces by using several CAD modeling packages (most notably, Rhino 3D and Grasshopper), a variety of laser cutters, pen plotters, and 3D printers, and a garage full of tools. David is a certified Rhino specialist (Levels 1 and 2) and has written a book on Grasshopper, the visual scripting plug-in for Rhino.

Lecture #6: Tutorial of model design and Workshop #2

This tutorial will demonstrate the software and tools used to take a mathematical idea, describe it analytically, and encode it as a 3D model. We will discuss three main approaches and tools for model creation: programmatic generation (scripting), mesh based sculpting, and NURBS modeling. The presentation will conclude with ideas and suggestions for the next workshop.

Lecture #3: Tutorial and demonstration of 3D printing software and tools and Workshop #1

In this talk we will give a down to earth demonstration of how to use an extrusion-based 3D printer, going through an entire example of how to turn a digital model into a physical one. We will go through the process of preparing a model for printing, explaining how to make sure a digital model is printable, and giving tips on how to recognize and troubleshoot common issues that arise.

She is also interested in using sewing, 3D printing and virtual reality in mathematical art and education.

Lecture #4: Mathematics and challenges behind 3D printing

3D printing is still a developing technology that faces many challenges, mainly mechanical, material, computational and algorithmic. The process of printing can be divided into three steps each offering its own mathematical problems: model design, preparation for printing via slicing and infill algorithms, and physical process of layer deposition in the printer. Optimizing these steps for printing time, cost, and physical qualities of the final product drives many challenges in this area. The printing processes itself can be quite complicated and prone to error. A common problem is a loss of alignment leading to splitting layers. Error correcting for such issues is an active field of research involving automatic feedback mechanisms and machine learning. Materials and dynamic properties of printed objects (i.e. their 4D behavior) are fundamental to successful uses in both industry and research. The goal of this lecture will be to introduce and explain approaches to these problems and discuss open questions and ideas.

I will also discuss generative work coming from dynamical systems and computational biology. Finally, I will talk about mechanisms and puzzles, both of which take advantage of the physicality of 3D printed objects to give experiences that cannot be matched by computer generated renders and animations

Lecture #2: Introduction to 3D printing

In this talk we will discuss the history of 3D printing and the revolutionary shift to additive manufacturing (AM), which differs dramatically from traditional manufacturing, allowing for fast prototyping and production of small or complicated pieces. Current applications include industry, dentistry and medicine (crowns, custom hearing aids, implants, prosthetics), footwear, architecture, aerospace and home products. In addition, AM is considered to be more eco-friendly than traditional because it uses material more efficiently. The lecture will include a detailed discussion of the variety of printer designs (extrusion, stereolithography, selective laser melting, etc.), fabrication materials (plastic, plaster, metal, glass, ceramic and even food), and solidifying process (drying, laser cut, and thermal.
