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.

Roblox Will Pay $12 Million to Settle Nevada Child Safety Lawsuit

The deal with the Nevada attorney general will require Roblox to have stricter safeguards to protect children online.

Popular gaming platform Roblox agreed to pay more than $12 million and implement new safety features as part of a settlement with the state of Nevada. This settlement comes amid several lawsuits accusing the company of an alleged lack of protection of children on the platform.

The agreement resolves potential litigation over allegations that Roblox failed to adequately safeguard children while they played the online game, Nevada Attorney General Aaron Ford said in a press release on Wednesday.

As part of the deal, Roblox will spend $10 million over three years to encourage children to engage in non-digital activities, as well as institute age verification for all users. This will include «facial age estimation technology and government-issued ID for age assurance, and will use behavioral monitoring to identify users who may have been aged incorrectly,» according to the press release.

«The injunctive relief that Roblox has agreed to will give parents the tools they need to protect their children on the platform; institute default protections to block predators from engaging with children; and ensure that messages involving minors are not encrypted,» Ford said in the press release.

Roblox also committed to spending $1 million over two years on a campaign to educate minors and adults about online safety and another $1.5 million to develop a law enforcement liaison position to work with state law enforcement agencies over concerns about the platform.

Roblox Chief Safety Officer Matt Kaufman said it’s part of the company’s «work to establish a new standard for digital safety.»

«This resolution creates a blueprint for how industry and regulators can work together to protect the next generation of digital citizens,» Kaufman said Thursday. «We have no finish line when it comes to safety.»

Roblox is under significant legal pressure amid more than 140 lawsuits, according to Reuters. The suits, filed in 2025, allege the company knowingly created a gaming platform that allowed child predators to target minors.

The company also faces lawsuits from state attorneys general in Texas, Kentucky, Louisiana, Iowa, Nebraska, Tennessee and Florida over similar accusations.

Age-based accounts coming soon

Two days before the settlement announcement, Roblox CEO and founder David Baszucki revealed new accounts for younger Roblox users.

Roblox Kids will be available for children between the ages of 5 and 8, and Roblox Select is for those ages 9 to 15. Roblox is reportedly used by nearly half of US children under 16. Children who are older than 16 will be in their own age group, simply called «Roblox.»

Kids and Select accounts would be available in those age groups as determined by Roblox’s age-check technology or by a verified parent.

Unmonitored chat in the game has been a point of criticism for the platform, as it allows predators to chat with children. Kids’ accounts will have chat turned off by default, with limited access to Minimal or Mild games as determined by the platform. Select accounts will have chat with safeguards and access to games with Moderate content, which is described by the platforms as having «moderate violence, light realistic blood, moderate crude humor, unplayable gambling content, and/or moderate fear.»

These new age-based accounts will roll out sometime in early June.

Opera Adds Browser Connector Feature to Integrate AI Chatbots Into Browsers

New feature will allow users to include the AI tools of their choice.

Opera announced Thursday the launch of a new tool that allows users of its browsers to include more AI chatbots in their browsing experience.

Browser Connector is a free feature for Opera One and Opera GX browsers that allows users to integrate AI tools such as OpenAI’s ChatGPT and Anthropic’s Claude into their live browsing sessions via Model Context Protocol. MCP is an open standard developed by Anthropic that allows for a secure two-way connection between AI models, external data sources and tools such as search engines.

(Disclosure: Ziff Davis, CNET’s parent company, in 2025 filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

Last month, Opera introduced MCP compatibility to Opera Neon, its subscription-based agentic AI browser. Opera says the new feature willallow a user’s AI of choice to provide real-time context of open tabs and active content.

«With Browser Connector, Opera ensures users aren’t bound to a single company’s ecosystem, but are instead free to combine the best tools for their specific needs,» Mohamed Salah, senior director of product at Opera, said in a statement.

To enable the feature, which is now available in Early Bird mode, users need to go to Settings in the browser, search for «AI Services» and install the Browser Connector feature. They then have to connect ChatGPT or Claude to the feature.
