Prusa MK4 3D Printer, Out Now, Follows Up Best in the Business

Prusa’s latest offering is said to be nearly three times faster than the excellent MK3, with better quality and accuracy. It’s available now for $1,099.

What’s happening

Prusa Research, a leading 3D printer manufacturer, has announced the MK4, the latest update to its popular Original Prusa line.

Why it matters

The original Prusa MK3 has been one of the best 3D printers for a long time. This new upgrade is supposed to make Prusa’s flagship even better.

What’s next

You can order the Prusa MK4 fully assembled for $1,099 or wait for the kit to ship for $799 in the coming weeks.

Prusa Research on Wednesday launched the Original Prusa MK4. Based on the same design as its MK3S Plus — a frequent pick as the best 3D printer on many sites — this new version has been upgraded in almost every way.

While there are few aesthetic changes to the shape of the MK4 compared to the MK3, there have been a lot of changes under the hood to bring it up to speed with the latest innovations in 3D printing. Many smaller details are quite technical, but the main points can be seen below. The upshot of these upgrades is a printer that promises accurate and detailed prints almost three times faster than the previous generation.

Faster print speeds through «input shaper and pressure advance» firmware updates
Hardware upgrades to better support speed and quality changes
Fast-swappable hot ends to let you use different size nozzles quickly
Nextruder extruder system
32-bit mainboard, which allows for Wi-Fi and Ethernet connections
Upgraded color LCD with model preview
Fully automatic bed leveling to improve your first layer
New multimaterial unit available as an add-on

Prusa has a reputation as a leader in the open-source 3D printing community. The MK4 will continue that tradition, allowing people to customize the machine how they want in the years to come. The company has also announced several upgrade kits that can upgrade your existing Prusa MK3 to variations of the MK4 — called the MK3.5 and MK3.9 — that will allow you to get almost all the MK4’s features, starting from $250.

Prusa announced the Prusa XL last year, but many of these have still not shipped. Because of this, the company has offered to switch preorders of the Prusa XL to the MK4 if you would rather pick up the smaller machine.

The Original Prusa MK4 is available now in a limited run, with more units to follow for $1,099, while the MK4 kit is due in the coming weeks. You can also order the upgrade kit for your MK3S Plus now if you want to upgrade rather than buy a new machine.

Bill Gates Has Published the Original Microsoft Source Code

It’s «the coolest code I’ve ever written,» the Microsoft co-founder says.

If you want to see the original source code that started Microsoft, Bill Gates is now sharing it. On Wednesday, the Microsoft co-founder posted it on his Gates Notes blog, reminiscing about the company’s early days for its 50th anniversary. Gates has written plenty of code in those five decades but he called this «the coolest code I’ve ever written.»

Sharing a photo of himself holding a huge pile of paper showing the code, Gates wrote that he was inspired by the January 1975 copy of Popular Electronics magazine. The magazine had featured a cover photo of an Altair 8800, a groundbreaking personal computer created by a small company called MITS.

The 19-year-old Gates and his Harvard pal Paul Allen reached out to Altair’s creators and told them they had a version of the programming language BASIC for the chip that the Altair 8800 ran on. Such software would let people program the Altair.

«There was just one problem,» Gates wrote. «We didn’t.»

Micro-Soft is born

Gates said he and friends «coded day and night for two months to create the software we said already existed.» Gates and Allen then presented the code to the president of MITS, who agreed to license the software. «Altair BASIC became the first product of our new company, which we decided to call Micro-Soft,» Gates wrote. «We later dropped the hyphen.»

And the rest, as they say, is software history. You can download that 50-year-old code from Gates’s post. «Computer programming has come a long way over the last 50 years, but I’m still super proud of how it turned out,» he wrote.

Melinda Gates: new book

Also making headlines this week was Gates’s former wife, Melinda French Gates, whose new book, The Next Day, comes out April 15. As that date approaches, she’s opening up about the end of her marriage to Gates.

The couple divorced in 2021 after 27 years and three children. According to People magazine, Melinda French Gates wrote in the book that in 2019 she was «having nightmares about a beautiful house collapsing all around her — and then waking up in a panic night after night.»

She acknowledged what Bill Gates has publicly stated — that he wasn’t always faithful in the marriage — and said she was also disturbed by Gates’s meetings with child sex offender Jeffrey Epstein. Bill Gates has since said he regrets meeting Epstein.

Melinda French Gates said her bad dreams would eventually change into images of her family on the edge of a cliff where she «plummeted» into a void. «I knew, in that moment, that I was going to have to make a decision — and that I was going to have to make it by myself,» she wrote, according to the People article.
