Supercharge Your 3D Printer With This Must-Have Upgrade

The new Revo Six hot end from E3D is an easy way to swap in different nozzles on your 3D printer.

Almost all the best 3D Printers can be upgraded in some way with new parts and accessories. One of the most important potential upgrades is to the machine’s hot end assembly, which controls the temperature your printer prints at, and houses the nozzle that helps determine the filament flow.

The Rapidchange Revo Six is a replacement hot end for your 3D printer. It’s from E3D, a company that’s been making parts for 3D printers for years and is one of the gold standards, especially for nozzles and hot ends. This new model has really changed how I use my 3D printers and how I think about the models I’m making.

With the Revo Six, you can swap out the nozzle part of a printer’s hot end easily, which allows for lots of variation in the materials and line thickness for your project. Normally you need to remove the filament from your nozzle, heat the nozzle to loosen the threads, undo it with a socket wrench while it’s hot, then let it cool. After that, you can install your new nozzle, but you need to install it cold, then retighten it once it’s hot.

The $93 Revo Six (£77 GBP) takes out a lot of steps by making the nozzle and other parts of the printing assembly one piece and fully removable by hand. Take out your filament, immediately unscrew the nozzle, and swap it out. This saves a lot of time when replacing nozzles that’ve worn out, but the real magic is swapping different-sized nozzles for different models.

Why you want different nozzle sizes

Often the purpose of your 3D model dictates the settings you’ll use to print it. When printing something delicate with a lot of details, you need a smaller nozzle diameter. With something structural that requires strength, you need a larger diameter. Most 3D printers come with a 0.4mm nozzle as standard, which is fine as a happy medium but won’t always be enough in either direction.

The genius of the Revo Six is the ability to change nozzle sizes almost on the fly. Each nozzle size is color-coded and available from 0.15mm all the way up to 0.8mm and can be replaced in less than a minute. The $89 kit comes with a 0.4mm nozzle but the $139 fully loaded kit has four nozzles ranging from 0.25 to 0.8mm.

I’ve printed a set of brackets for a machine I needed to mount to the wall. The mount is completely hidden and layer lines don’t matter, so I used the 0.8mm nozzle to print extra thick, extra strong parts as quickly as possible (larger layer lines mean faster printing too). As soon as I’d finished the brackets, I immediately swapped the nozzles on the Revo Six to the 0.25mm one and started printing a Flower Dragon with tiny details from Fotis Mint. Having that flexibility in a single machine is fantastic. It saves money on different printers and, more importantly, saves me time, something I have very little of day-to-day.

Upgrade the upgrade with the E3D Obxidian

Like all good 3D printing accessories, even the Rapidchange Revo V6 can be upgraded. Not only did E3D produce low-cost replacement nozzles for all the different sizes you might want, they made a specialty nozzle for the exotic filaments too.

The Obxidian (pronounced obsidian, like the rock) is a nozzle from E3D that’s specially designed to help combat the wear and tear you get from using abrasive materials infused with other mediums, such as wood or carbon fiber. It’s made from copper, rather than a brass alloy, and has a special coating that helps move the fibers through the nozzle without sticking. It’s also designed to work with the Revo system for quick changing.

Buzz phrases like «the last nozzle you’ll ever need» feel hyperbolic, but at the same time, the longevity of the $59 Obxidian compared with standard nozzles — it can last indefinitely as long as you aren’t using glow-in-the-dark filament at high speed — makes me wonder if it’s even worth buying a standard Revo nozzle again. Actually, the Obxidian comes only in 0.4mm and 0.6mm diameters, so it’s worth having the other nozzle sizes around for other print jobs. Filaments with other materials in them — wood or carbon-infused PLA for example — benefit from a high flow rate, so larger nozzle sizes work better for the Obxidan. For standard prints, though, the Obxidian has everything covered.

An accessory that elevates your entire machine

All the best 3D printing accessories improve your experience in some way, but the Revo Six coupled with an Obxidian nozzle will fundamentally change how you print. Because so many manufacturers have used the E3D V6 hot end in some fashion, the company was able to create Revo Six systems that are easy to replace on a huge variety of 3D printers. From Creality to Prusa, E3D has Revo to help you convert.

I’m convinced that the Rapidchange Revo Six is the next big change to hot ends moving forward, and though I haven’t managed to convert all my 3D printers, if you have just one or two, then investing in a fully loaded kit is well worth it.

Apple Launches Creator Studio Package as $13 a Month Subscription

Mac users can still buy the apps individually, but subscribers get access to Final Cut Pro and other Studio tools.

Apple is bundling its pro filmmaking and audio tools including Final Cut Pro with its productivity apps Keynote, Pages and Numbers into a subscription software suite called Apple Creator Studio.

The package, which includes apps for Mac, iPad and iPhone, includes Logic Pro, Pixelmator Pro, Motion, Compressor, MainStage and the whiteboard app Freeform. Creator Studio will be available starting Jan. 28 at a cost of $13 per month or $129 per year, or $3 per month or $30 per year for students and educators. Mac users will still have the option to purchase software like Final Cut Pro for a one-time free. The current price for Final Cut Pro in the Mac App Store is $300.

While apps such as Keynote and Pages are already free on Apple platforms, it appears that new versions of those apps will receive access to beta features that will roll out first to Creator Studio subscribers. The announcement by Apple alludes to «new AI features and premium content» in some of the apps it otherwise makes available to use for free.

What the Creator Studio bundle comes with

The star of the show in Creator Studio is Final Cut Pro, the video editing software that will now include Transcript Search on both Mac and iPad. There is also a new Beat Detection feature Apple says uses an AI model to analyze a music track and display a beat grid, making it easier to cut video to music rhythms. The software also will include a new Montage Maker on iPad for quick social video creation.

Motion, the 2D and 3D graphics tool, and Compressor also integrate with Final Cut Pro. Apple touted Motion’s Magnetic Mask feature for isolating objects or people without the need for a green screen.

Logic Pro has new features for musicians, including a Synth Player addition to AI Session Players. Chord ID, a new AI feature, can create chord progressions from audio or MIDI recordings. A new Sound Library will have hundreds of royalty-free clips, samples and loops.

A revamped MainStage app gives subscribers access to instrument, voice-professing and guitar rig tools. Pixelmator Pro arrives with new tools and filters, and there will be an iPad version in addition to the Mac tool.

Freeform in the Creator Studio package will add premium content, including curated photos, graphics and illustrations. It will also get new AI features that include image creation.

Reddit Outage Resolved: Here’s What Happened

Did you have trouble reading your favorite subreddits today? You weren’t alone.

If you had trouble accessing the news and discussion forum Reddit on Tuesday, you weren’t the only one. However, as of 10:15 a.m. PT, the site appears to be back up and running normally. Reddit’s status monitoring page, RedditStatus.com, notes that «all systems (are) operational» after the brief outage.

But earlier, at 9:30 a.m. PT, RedditStatus.com said the company was «investigating elevated errors across reddit.com and native apps.» RedditStatus.com reported degraded site performance for both desktop web use and native mobile apps.

Earlier on Tuesday, the site-monitoring service DownDetector also reported issues at Reddit, providing additional details. At one point on Tuesday, DownDetector received over 100,000 reports that the site was having problems. At 10:25 am PT, the report numbers fell to under 600. (Disclosure: Downdetector is owned by the same parent company as CNET, Ziff Davis.)

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

«Reddit is currently experiencing a significant internal outage causing widespread service disruptions,» the site said earlier Tuesday. «The impact is categorized as Very High, primarily affecting mobile app access (55%) and website connectivity (39%). While reports are heavily concentrated in major hubs like New York City and Chicago, the lack of ISP correlation suggests a broad, nationwide issue stemming from Reddit’s internal servers rather than external network providers.»

A representative for Reddit did not immediately respond to a request for comment. Another social media site, X, formerly Twitter, also showed problems on Tuesday, according to DownDetector. Those problems seemed to spike around 6:30 a.m. PT and improve after.
