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.

AI-Voiced Darth Vader Can Swear, Say ‘Skibidi Toilet’ in Fortnite: How to Find It

Expletives are apparently not off the table as a foul-mouthed AI Darth Vader is added to Fortnite.

It didn’t take long after Epic Games unleashed famous Star Wars Sith lord Darth Vader into the game Fortnite — complete with the AI-enabled voice of late actor James Earl Jones for conversations with players — for Vader to drop the F-bomb.

As seen on multiple social-media videos, Vader can be prompted to say lots of things you wouldn’t find in a Star Wars script, such as curse words, «Skibidi toilet» and to share his thoughts on breasts.

A representative from Epic Games pointed to a post on X saying that the company has already addressed the apparent lack of language filtering. The post reads, «We pushed a hotfix immediately and this shouldn’t happen again.»

But gamers were apparently able to capture footage of inappropriate banter from Vader in the time before the fix was issue. Epic is asking gamers to report any additional problems.

Safety filters to stop the swearing

A representative for Epic Games told CNET on Friday that there are three layers of safety filters built into the feature to prevent this from happening again.

Also, parents must enable the option to «allow voice and written communication with AI features» for kid accounts to speak with Vader.

And even the Dark Lord of the Sith can still get kicked out of the game.

«If a player is repeatedly attempting to get Darth Vader to violate our settings and instructions, he will eventually leave the squad, and the player will be unable to recruit him again in that gameplay session,» the representative said. «If we become aware or receive a bug report that Darth Vader in Fortnite responded in a way he shouldn’t, we investigate it and if needed, make adjustments to avoid similar responses in the future.»

Where is this F-bomb dropping Vader?

It’s likely you’ve missed the window to have an R-rated conversation with Luke Skywalker’s father — although you can find clips that others have saved and posted on social media.

But Vader can still be found in Fortnite’s Battle Royale mode in the Samurai’s Solitude area in the southwest of the map. Your party can recruit the new Vader, who replaced Samurai Vader, and have an AI chatbot conversation with him. Epic used Google’s Gemini 2.0 Flash model for the responses.

The family of Jones, who voiced the character since the first Star Wars movie, gave Epic permission to use his voice with AI models.

«James Earl felt that the voice of Darth Vader was inseparable from the story of Star Wars, and he always wanted fans of all ages to continue to experience it,» the family said in a statement. «We hope that this collaboration with Fortnite will allow both longtime fans of Darth Vader and newer generations to share in the enjoyment of this iconic character.»
