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.

Hint for today’s Strands puzzle

Today’s Strands theme is: You need to chill

If that doesn’t help you, here’s a clue: Brrrr!

Clue words to unlock in-game hints

Your goal is to find hidden words that fit the puzzle’s theme. If you’re stuck, find any words you can. Every time you find three words of four letters or more, Strands will reveal one of the theme words. These are the words I used to get those hints but any words of four or more letters that you find will work:

GONE, ABLE, TABLE, FOOD, TEEN, LEAF, GOOF, GOOD, SAFE

Answers for today’s Strands puzzle

These are the answers that tie into the theme. The goal of the puzzle is to find them all, including the spangram, a theme word that reaches from one side of the puzzle to the other. When you have all of them (I originally thought there were always eight but learned that the number can vary), every letter on the board will be used. Here are the nonspangram answers:

PIZZA, SHERBET, POPSICLES, WAFFLES, VEGETABLES

Today’s Strands spangram

Today’s Strands spangram is FROZENFOOD. To find it, start with the F that is five letters down on the far-right row, and wind backward.

#2: Thar she blows! I guess marine biologists might ace this one. Toughest word: BALEEN or RIGHT.

#3: Off the hook. Again, it helps to know a lot about sea creatures. Sorry, Charlie. Toughest word: BIGEYE or SKIPJACK.
