Interview: Grace X. Gu, UC Berkeley, developer of a self-correcting 3D printer

In 2017 multinational pharmaceutical firm Johnson & Johnson, launched the WiSTEM2D Students Award program to extend the illustration of ladies in six scientific and technical fields. Open to assistant and affiliate educational professors from throughout the STEM area, winners of the prize are awarded $150,000 in funding and three years of mentorship from Johnson & Johnson to assist assist crucial advances of their careers.

The 2019 winner of the WiSTEM2D is Grace X. Gu. A part of the Mechanical Engineering school at UC Berkeley, Professor Gu has carried out pioneering work within the area of additive manufacturing, together with current work on a self-correcting 3D printer. 3D Printing Trade received in touch with Professor Gu to to be taught extra about this specific challenge, and future hopes for 3D printing in training.

A self correcting 3D printer

Gu has been concerned in additive manufacturing for the final 5 years, and joined the UC Berkeley school of Mechanical Engineering in 2018 after ending her PhD. Since then she has been seeking to tackle the restrictions of additive manufacturing.

An necessary pillar of Gu’s work has been the event of a self correcting 3D printer. The purpose is to create a 3D printer able to “detecting frequent points” throughout manufacture (resembling overhanging, underextrusion, stringing, porosity, dimensional tolerance) and regulate printing parameters to repair the problems in actual time. With a purpose to obtain these outcomes, Professor Gu has developed a machine studying program for the 3D printer.

“In the course of the printing course of,” Gu explains, “pictures of the half might be fed right into a machine studying classification mannequin that may classify the issue (or no drawback) and use information generated throughout its coaching interval to information the subsequent knobs to show to repair the issue.”

“At present, we’re engaged on this mannequin for numerous polymers (PLA, ABS, TPU, PC) however hope to increase it to metallic supplies as nicely sooner or later. We consider comparable framework might be utilized for numerous supplies (although classification labels could also be barely totally different for various supplies).”

The general purpose of Professor Gu’s work is to make quicker, extra dependable 3D printers that waste much less materials, and have implications for the broader manufacturing sector. Professor Gu provides, “We consider that bringing this streamlined manufacturing course of to the economic degree will assist introduce the merchandise of tomorrow, resembling custom-made medical units and environment friendly photo voltaic cells, to our on a regular basis lives.”

Information is vital

The event of the self correcting 3D printer is what earned Professor Gu the 2019 Johnson & Johnson Girls in STEM2D award within the area of producing.

Commenting on her win she stated, “I’m so grateful to Johnson and Johnson for this award and am excited to make use of the funding to work with the undergraduate and graduate college students in my lab to additional develop the self-correcting expertise.”

Gu now plans to spend time together with her college students to develop the code and interface mandatory to construct these school-friendly 3D printers.

Nevertheless these printers should not very helpful if college youngsters don’t know the right way to use them, which is why Gu goes to nice size to contain herself in decrease training.

Talking on the subject of introducing consumer pleasant 3D printers for the classroom, Gu stated, “At present, there are quite a lot of limitations to 3D printing as a result of studying the right way to create the designs utilizing Pc Aided Design (CAD) has a steep studying curve. I hope to collaborate with academics and produce to their school rooms user-friendly, accessible 3D printers.”

Her goal to create a simplified CAD software program, like Tinkercad with “pre-defined” shapes that college students will be capable of use as “primary constructing blocks” for his or her designs. “I need to make it open-source in order that educators world wide can additional develop this 3D printer and incorporate it into their college curriculum,” Gu stated.

Not limiting studying to varsities both, a lot of Professor Gu’s central concepts concentrate on enabling finish customers – of any age – to manufacture objects of curiosity with out information of fabric science and design.

“On this case, customers should not restricted to inputting CAD drawings to a printer interface, however moderately high-level descriptions of the thing they need (weight, operate, property necessities) which the pc will use to generate shapes and select supplies that fulfill the consumer’s necessities,” she stated.

Getting extra girls curious about additive manufacturing

Regardless of her personal successes Professor Gu nonetheless sees steep studying curves and insufficient infrastructure as a barrier to girls getting into the additive manufacturing sector.

“Personally, I’m curious about growing a summer time workshop for highschool females to get a hands-on 3D-printing expertise” Gu explains. “On this workshop, they’ll experiment by way of design modulus the place they discover ways to use CAD, design their very own contraptions, and watch them be manufactured with 3D printers.”

By way of this the scholars may have the chance to realize a deeper understanding of additive manufacturing by getting palms on with supplies and 3D printing machines.  

Gu added, “I hope with this early publicity to additive manufacturing, we are able to empower extra females to pursue careers on this area.”
