3D Printed Chip Packages Could Supercharge Semiconductor Manufacturing
AUSTIN, Texas — Engineers at The University of Texas at Austin are leading an academic and industry all-star team that aims to revolutionize the production of semiconductor chips with a new 3D printing method. The new approach, which the researchers are calling Holographic Metasurface Nano-Lithography (HMNL), aims for faster, more efficient and environmentally friendly production of advanced electronics.
HMNL has applications ranging from smartphones to robotics to aerospace. It can create designs that were previously impossible, such as 3D printed capacitors, which store energy in electronic devices, or electronic packages that fit into unconventional spaces. For example, it would make it possible to embed artificial intelligence in customized configurations to fit the specifications of robots or rockets.
“Our goal is to fundamentally change how electronics are packaged and manufactured,” said Michael Cullinan, an associate professor in the Cockrell School of Engineering’s Walker Department of Mechanical Engineering, who is leading the team. “With HMNL, we can create complex, multimaterial structures in a single step, reducing production time from months to days.”
The team, comprising researchers at the University of Utah, Applied Materials, Bright Silicon Technologies, Electroninks, Northrop Grumman, NXP Semiconductors and Texas Microsintering, has received a $14.5 million grant from the Defense Advanced Research Projects Agency (DARPA) to pursue this work.
Electronics manufacturing today is a complex, time-consuming process that involves layering materials one step at a time. This approach not only limits design flexibility but also generates significant material waste. HMNL offers a faster, more sustainable alternative.
The key to this technical leap lies in metasurfaces, which are ultra-thin optical masks capable of encoding high-density information. When exposed to light, these metasurfaces create holograms that enable the simultaneous patterning of a hybrid resin made of metal and polymer into intricate 3D structures. The process is so precise that it can achieve resolutions smaller than the width of a human hair.
Additionally, by eliminating multiple production steps and reducing material waste, the process minimizes the environmental footprint of industrial activities. The increased speed will make it easier to develop unique prototypes.
The researchers created four prototypes as part of this project for a variety of applications:
- Commercial electronics: A fan-out module for consumer devices, showcasing faster production and improved design flexibility.
- Defense systems: Advanced prototypes for high-frequency communication and reconfigurable electronics.
- Nonplanar designs: Electronics packages that fit into challenging spaces.
- Active packages: Structures that serve mechanical and electrical functions, such as precise beam-pointing systems for optical applications.
“This isn’t just about making electronics faster or cheaper; it’s about unlocking new possibilities,” said Cullinan.
The researchers plan to commercialize the technology through Texas Microsintering Inc., a startup founded by Cullinan.

Austin Animal Services Hosts Free Spay/Neuter Clinic
Austin Animal Services is hosting a free, high-quality, high-volume spay/neuter for cats and dogs now through March 2 in North Austin.
The five-day clinic, which is being held in partnership with Greater Good Charities, is taking place at 11580 Stonehollow Dr., Suite 160. Registration and drop-off begin on-site each day from 7:30-10 a.m. or until capacity is reached.
In addition to free spay/neuter surgeries, pets receiving surgery will also receive vaccinations, flea and tick prevention, and microchips, ensuring that they return home healthier and better protected.
Spaying and neutering is the most effective tool in preventing unplanned litters and reducing the number of stray and surrendered animals entering local shelters. Managing overpopulation helps individual owners and also strengthens community health by reducing roaming animals, easing shelter overcrowding, and decreasing long-term strain on animal welfare resources.
This is the seventh free clinic the city has hosted since 2024. The previous six clinics provided spay/neuter services to more than 6,000 pets. The upcoming clinic is expected to complete approximately 1,200 surgeries in just five days. It is a significant investment in prevention that helps reduce future shelter intake and supports responsible pet ownership across Austin.
High-volume, high-quality spay/neuter clinics offered at no cost are rare, and many pet owners face procedure costs ranging from $75 to several hundred dollars, along with wait times that can stretch for weeks or months. This clinic removes those barriers by providing same-day services at no charge.
“This clinic is about prevention,” said Austin Animal Services Director Monica Dangler. “When we provide accessible spay and neuter services, we’re helping families care for their pets while also reducing strain on shelters like ours and improving safety across our community.”

Why is Austin so warm in February?
AUSTIN, Texas — February is typically one of our cooler months in Austin, Texas.
In 2021, a series of ice storms and snow storms caused mass chaos and is a winter storm that Austinites will never forget. Now, instead of worrying about scraping ice off of our cars, we’re grabbing the swimsuits.
Austin is in the midst of one of the warmest February’s in the city’s history. This year’s January cold snap lingered around for Feb. 1, but since then, only two days have been slightly below average. Compare that with 20 days above average, with the rest of this month expected to have temps in the mid to upper 80s.
But how does this compare to our warmest February ever? We don’t have to go back too far to find the hottest February on record in 2017. The average high temp was 76.5 degrees with 12 out of the 28 days spent above 80 degrees.
Other years in the top 5 were 1999, 1976, and 1957 with each year having numerous days above 80 degrees. So far, 2026 has ten. Plus, I’m forecasting 2 more 80 degree days. Should we hold onto this weather pattern, this will be in the top five hottest February’s of all-time.

For some, this heat may be just another day to grab the swimsuit or head outside and work up a sweat, but this has meteorologists sweating for different reasons. We are in a serious drought now.
The latest drought monitor released on Feb. 26, 2026 has 9 of the 13 counties in the CBS Austin viewing area in an “extreme drought,” which is the second worst category of drought conditions.

In the past 190 days, two of those days have had rainfall over 1 inch. Our current streak of 123 days in a row with less than 1 inch in rainfall is one of the longest since 2000.
Combine the heat and the rainless days, and you get a flash drought. Opposite of a flash flood, hot temperatures rapidly dry out the soil and drought conditions can worsen quickly. With the dehydrated vegetation, dry air, and above average temperatures, you’re now looking at dangerous fire weather.
We’ve already had several fires reported across Central Texas in just the past week. The Nebo Mountain Fire in Gillespie County and the Cedar Gulch Fire in Burnet County. With this above average heat and below average precipitation, we are especially vulnerable.
But there is some good news.
The start of March looks to be starting off very warm, but our pattern looks to become a bit more active. Our long-term futurecasts look to be favoring more showers and storms possible for the first few weeks of March.
Remember that we are also getting closer to our severe weather season. So while we do need the rain, we must remain safe in case we get locally high rainfall amounts in these thunderstorms and be mindful of tornadoes and damaging winds.
Hopefully we can see an improvement in this drought and heat, but history is made in different ways every year nowadays. Maybe it’ll be for the right reasons this time around.
