A 3D printer that can make a structure in about 20 seconds sounds like a lab claim wearing a cape. The clever bit is real. The catch arrives before anyone starts dreaming about instant replacement parts.
University of Utah researchers have demonstrated a holographic 3D printing technique that hardens tiny structures in one exposure instead of building them layer by layer. That one-shot approach could avoid the weak, leaky seams that stacked printing can leave behind. For now, though, this is a tool for microstructures, not a shortcut to printing whatever object pops into your head.
How one shot replaces layers
The technique borrows from photolithography, then pushes the idea into thicker material. A nanopatterned mask sits in front of the laser and shapes the light before it enters the print material.

That material is SU-8, a substrate whose polymer strands harden when exposed to laser light. After the targeted volume sets, the unexposed material can be washed away. Instead of tracing a shape through slice after slice, the system hardens the useful structure at once.
Where the catch shows up
The breakthrough is narrower than 3D printing sounds. The printer can control the length and width of a pattern, then extend that pattern through height. That makes it powerful, but still boxed in.
That limitation explains why the first demonstrations involve microtubule arrays and lattice patterns rather than tiny desktop ornaments. The approach suits intricate designs that need to run through a thick volume. Objects that require different geometry at different depths still need a more flexible version of the technology.

What this could print next
The useful version of this probably won’t resemble a home 3D printer. It looks more like a manufacturing tool for tiny parts where internal structure does the hard work.
The printed microtubules were tested for liquid movement through capillary action and for toughness under compression. That points toward lab-scale structures where small details have to survive real forces. The next step is clear enough. Researchers need to turn a fast extended-2D trick into true 3D control without losing the 20-second advantage.
Reality makes for some stellar storytelling. If you’re looking to stream movies that are based on true events, Netflix has an extensive collection of biographical-style dramas that go beyond your typical selection of documentaries.
From historical tragedies to stories of resilience and ambition, these films bring some notable real-life events to your screen. Here are five Netflix Original movies that feature strong performances, storytelling, and visuals that you need to add to your watch list for the week.
The Two Popes

The Two Popes is an incredible film that is based on one of the most memorable recent transitions in modern Catholic Church history, led by strong performances from Anthony Hopkins and Jonathan Pryce.
Inspired by real conversations and events surrounding Pope Benedict XVI and the future Pope Francis, The Two Popes follows Cardinal Jorge Mario Bergoglio as he travels to Rome and plans to resign from the Church. Instead, he finds himself pulled into a series of personal and philosophical conversations with Pope Benedict, who is struggling with his doubts about leadership and the future of Catholicism. The character focus of the movie keeps you hooked despite the mellow pace, with Hopkins’ and Pryce’s chemistry making for an impeccable watch.
The Two Popes received nominations at the Academy Awards, Golden Globes, and British Academy Film Awards.
Society of the Snow
Hope is within the group
One of Netflix’s most notable, foreign-language survival thrillers is Society of the Snow. Based on the real 1972 Andes plane crash, the Spanish movie follows a Uruguayan rugby team whose flight crashes deep in the snow-covered mountains, leaving the survivors stranded for weeks in brutal freezing conditions. As supplies start to run out and hope fades, the group is forced to make some unimaginable decisions just to survive.
The thriller was shot mainly in Sierra Nevada, Spain, and features some phenomenal filmmaking. Although survival is a core element of the movie, it also highlights the grit and humanity of the party amid a disastrous situation, alongside the grim reality. Society of the Snow received two Academy Award nominations for Best International Feature Film and Best Makeup and Hairstyling.
The Good Nurse
The case of a prolific, unexpected killer

The Good Nurse was haunting to watch at night, but it’s a thriller that has stayed with me for years. The crime drama tells the true story of Charles Cullen, a nurse and serial killer who was responsible for the deaths of dozens of patients across multiple hospitals in the United States. The film is based on the 2013 true-crime book of the same name by Charles Graeber.
What’s fascinating about the movie is that, instead of giving us Cullen’s perspective, the story unfolds from the POV of Amy Loughren, a single mother and ICU nurse who was key in Cullen’s confession and eventual conviction. As his new co-worker, her suspicions build over the course of the movie after she starts noticing something strange about his patients. The Good Nurse also does a good job of touching on another vital aspect of the case, the hospital’s negligence.
Jessica Chastain and Eddie Redmayne drive the movie with incredibly controlled performances. To know more about the real case, you can also check out the Netflix documentary Capturing the Killer Nurse.
Mudbound
Life after war is never easy

The (mandatory) war film addition to this list is Mudbound, a Netflix exclusive that stands out for its incredible character-focused storytelling. The story is set in rural Mississippi after World War II and follows two veterans, one Black and one white, whose lives become intertwined while working on the same farmland. The soldiers and their families deal with the PTSD of war in their own ways. Mudbound explores themes like racism, trauma, class divides, and poverty through its gripping plot.
Directed by Dee Rees, the film received four Academy Award nominations, including Best Supporting Actress, Best Original Song, and Best Adapted Screenplay. It became the first Netflix movie ever nominated for Best Cinematography — Rachel Morrison became the first woman nominated in the category. It also earned two Golden Globe nominations.
Nyad
An impossible feat is nothing for this resilient athlete

If you’re in the mood for a sports thriller and a true story, don’t skip NYAD. This biographical drama follows marathon swimmer Diana Nyad and her attempt to complete the seemingly impossible 110-mile swim from Cuba to Florida without a shark cage. The film takes place years after Nyad initially gave up on the challenge.
The athlete decides in her sixties that she wants a final shot at achieving the record-breaking swim and sets her mind on the incredible goal. Alongside her best friend and coach, Bonnie Stoll, Nyad begins preparing for the physically exhausting journey while facing dangerous weather, exhaustion, and many failed attempts. NYAD is led by Annette Bening and Jodie Foster, with both actors receiving nominations for Best Actress and Supporting Actress, respectively, at the 96th Academy Awards and the 81st Golden Globe Awards.
