by Tasia Williams

This fall 2016, Tasia Williams, graduate student in Museology at the University of Washington presented a poster at the Western Museum Association Conference in Phoenix, Arizona.  She presented research about her work experimenting with producing 3D printing replicas of archaeological artifacts from the Burke Museum, including a walrus bone cup found in Seattle.  This project arose out of an interdisciplinary class offered through the Mechanical Engineering Department and the Burke Museum and was taught by Steven Weidner.  This class focused on digitizing and printing paleontological fossils from the museum’s collection.

According to Tasia “I applied what I learned in that class to solve the unique problems involved with modeling and printing artifacts. 

The Solheim Additive Manufacturing Lab was invaluable in helping me experiment with this project.  I wanted to try out non-extruding printers (powder printing or ASTM binder jet printing), but I found that I needed help.  Kim Sokol, a senior Mechanical Engineering student, assisted me by using her knowledge to print out several artifact replicas on the powder bed printer.

I am incorporating this research into my thesis which will examine the ways museum visitors learn from 3D printed replicas of museum artifacts.  I want to thank Professor Ganter, Kim, and everyone else at the lab for helping me with this project.  I couldn’t have done this project without them!”

Abstract:

Purpose:   The purpose of this paper is to explore the improvements in speed and precision achievable using straightforward closed-loop control for the gantry motion in additive manufacturing machines. The authors designed and built an economically viable demonstration system to quantify the performance improvement.

Design/methodology/approach: The authors develop and evaluate a low-cost closed-loop controller for the X and Y axes of an entry-level three-dimensional (3D) printer. The system developed captures and compensates for the dynamics of the motor and the belt-driven stage and detects mechanical errors, such as skipped motor steps.

 
Findings: The system produces path-following precision improvements of 40 and 75 percent for two different sample trajectories. Correcting for skipped steps increases reliability and allows for more aggressive tuning of motion parameters; time savings of up to 25 percent are seen by doubling acceleration rate.
 
Research limitations/implications: The system presented provides an appropriate platform for further investigation into more complex, application-specific controllers and inclusion of more details of the printer dynamics that could produce still greater improvements in speed and accuracy.

 

Practical implications: The performance, low cost (40 USD/axis) and applicability to the majority of sub-2000USD 3D printer designs make this work of practical significance.

Originality/value: The CNC machining industry has for many years used similar approaches, but application to 3D printers has not been explored in the literature. This paper demonstrates the value of even a simple controller applicable to almost any 3D printer, while maintaining cost-effectiveness of the solution in a competitive market.

 

Acknowledgments: This material is based on work supported by the National Science Foundation Graduate Research Fellowship Program under Grant No. DGE-1256082, which supported the lead author throughout the research process. The authors also gratefully acknowledge the insight of Matthew D. Sorensen, as well as the helpful comments of the reviewers.

Congrats goes out to the team of researchers:  John Klein, Michael Stern, Giorgia Franchin, Markus Kayser1, Chikara Inamura, Shreya Dave, James C. Weaver, Peter Houk, Paolo Colombo, Maria Yang and Neri Oxman.

This team has presented a working 3D transparent glass printing system!   While we know of three other teams working in this exact idea, this teams successful results are amazing!

And upcoming article in 3D Printing and Additive Manufacturing:

“Additive Manufacturing of Optically Transparent Glass

Abstract
We present a fully functional material extrusion printer for optically transparent glass. The printer is
comprised of scalable modular elements, able to operate at the high temperatures required to process glass from a molten state to an annealed product. We demonstrate a process enabling the construction of 3D parts as described by Computer Aided Design (CAD) models. Processing parameters such as temperature, which control glass viscosity, and flow rate, layer height and feed rate, can thus be adjusted to tailor printing to the desired component, its shape and its properties. We explored, defined and hard‐coded geometric constraints and coiling patterns as well as the integration of various colors into the current controllable process, contributing to a new design and manufacturing space. We report on performed characterization of the printed material executed to determine their morphological, mechanical and optical properties. Printed parts demonstrated strong adhesion between layers and satisfying optical clarity.

Demonstration of this molten glass 3D printer and fabricated objects demonstrates the production of parts, which are highly repeatable, enable light transmission, and resemble the visual and mechanical performance of glass constructs that are conventionally obtained. Utilizing the optical nature of glass, complex caustic patterns were created by projecting light through the printed objects.    The 3D printed glass objects described here can thus be extended to implementations across scales and functional domains including product and architectural design. This research lies at the intersection of design, engineering, science and art, representing a highly interdisciplinary approach.”

{Pilchuck Glass School}

In Session 3 of the 2015 summer program at Pilchuck Glass School, a new class on Digital Fabrication was offered.  The instruction team consisted of Fred Metz,  Mark Ganter,  Josh Kopel,  Matt Sorensen,  Tim Belliveau, and  Julia Chamberlain.   The class consisted of hands-on exposure to the latest 3D CAD and 3D printing software as well as both plastic material extrusion (filament) and binder jetting (powder) 3D printing systems.    Our students were brave and fierce in their desire to absorb new techniques and technology.

{Class getting ready for a metal casting pour into Lost-PLA investment molds}

The class designed and 3D printed their hearts out for the fabrication of press molds for sand casting glass, and lost-PLA investment molds for metal and glass.

The instruction team also brought a 3D binder jetting printer (powder printer) to Pilchuck to directly 3D print molds and glass.

{3D printed hydroperm molds for kiln casting glass}

One of the very last events of the class, direct 3D printing of boro-silicate glass (compliments of David Winship).   David brought along some samples of recycled boro-glass and his ball mills for the production of glass powder.  He screened the powder for printing and we 3D printed it.

pgs4v2

{3D printed boro-silicate glass via VitraGlyphic process}

This is a first in the 3D printing community (as far as I know).   This was the very first 3D printing of boro-silicate glass using 3D binder jetting.   It was a great success.

Overall, the class was a smashing success.   We came.   We designed in 3D CAD.   We 3D printed.   We made glass and metal artifacts.  We celebrated our success.  We had a blast.

Four sophomore students who were all members of the student 3D printing club:WOOF, set out to design and fabricate a large format printer (during one academic quarter of 2014).  They are the third team to undertake this task. The team was composed of  Jeff Bergeson,  Nicole Bentzen,  Daniel Palomaki, and Kim Sokol.

{Rendering of the overall design concept}

“Over the past ten weeks our team has designed and built a large scale, multi-format
3D printer. Our project began where another project left off, with a preexisting printer that was very limited in many aspects. Our goal was to create an entirely new printer with the ability to extrude a variety of paste materials while still maintaining a high quality resolution and large scale. In addition, we aim to make the printer easy to use, and easy to transport. We went through the entire process of redesigning, building, and testing a new KiloPrint.”

{KiloPrint with the design/fabrication team}

“KiloPrint has a maximum build volume of 21”x33”x32… The cost of building KiloPrint, taken directly from our Bill of Materials, is around $1300. Though KiloPrint has a smaller build volume than the Brand-X, it is literally 1/10th the cost. Furthermore, the price of KiloPrint would continue to go down if it was manufactured in bulk. In addition, KiloPrint is also mobile and can print in multiple materials… we have plans to retrofit it with the ability to print in plastic as well. KiloPrint is still in the first stage of development; therefore it is not yet refined enough for retail sale. With these things in mind, it is safe to say that KiloPrint is rapidly becoming more and more competitive in the large scale 3D printer market.” – 6/15/2014

Over the course of the current school year, the KiloPrint team has been busy with their studies. However, they HAVE tested several versions of plastic filament heads on its gantry.   They printed several full size rocket bodies and other rocket assembly parts {a future post}.   Recently they added a volcano style extruder to KiloPrint with some very good results.

It seems like everyone is getting on the DLP bandwagon in the 3D printing space as of late.  While we have known about DLP 3D printing (i.e. vat photopolymerization process – ASTM F2792 − 12a)  for some time, we had chosen to stay away mostly due to resin issues.   Over the past few years, many new resin formulations have become available and many are both low in odor with toxicity within reasonable limits (in fact several resin systems are open sourced).  When you combine the improved resin systems with substantial activity in crowd funding sites and IRC chat, we decided to jump in to see what all the flashing lights were about.  We purchased a couple of systems and have been exploring both overall print system and resin concepts.

We have been experimenting with creation and printing of structured and unstructured tetrahedral meshes over the past several months.  Our work has just been for fun and experimentation.     It currently involves multiple steps through different software systems (we are working on reducing what’s required).  Please notice that the animals are completely filled with tetrahedral structures (it is not simply a surface shell structure).

We are pleased to present:
