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.

Pope Francis’ Funeral: How to Stream Live or Watch the Replay

Here’s how to stream the pope’s funeral very early Saturday, and what you can expect to see during the service.

After a week of global mourning for Pope Francis, who died on Monday at age 88, the pope’s funeral will be celebrated on Saturday . Francis’ funeral will be held Saturday at 10 a.m. local time at St. Peter’s Square in Vatican City (which is very, very early if you’re tuning in from the US or Canada), and he will be laid to rest at the Papal Basilica of St. Mary Major in Rome.

The Vatican will be livestreaming the papal funeral and procession, though not the burial, on its YouTube channel as it happens. The funeral will also be televised live on CBS, NBC, ABC and Fox, as well as on streaming services like Disney Plus, Hulu, Peacock and Paramount Plus. Due to the time difference, it seems likely that many interested North American viewers will catch it when it’s replayed later on Saturday. Numerous networks will rebroadcast the service later that day.

If you choose to stay up, or get up early, here’s when the live broadcast of the pope’s funeral will air in your time zone in the continental US on April 26:

ET: 4 a.m.
CT: 3 a.m.
MT: 2 a.m.
PT: 1 a.m.

The papacy of Pope Francis was notable for the progressive reforms he brought to the Roman Catholic Church. He appointed more than half of the current College of Cardinals and attempted to foster more positive attitudes toward members of the LGBT community and migrants worldwide.

What to expect from the funeral

The funeral will follow many rituals, though not all traditional protocols will be followed. Most popes are buried in St. Peter’s Basilica or its grottoes, but the AP reports Francis chose the St. Mary Major Basilica to reflect his veneration of an icon of the Virgin Mary that is located there, the Salus Populi Romani (Salvation of the People of Rome).

His funeral will be less elaborate than those of other popes per his own wishes. Francis simplified papal funeral rites last year, permitting his burial outside the Vatican, and emphasizing his role as a bishop rather than as pope (the pope is also the Bishop of Rome).

Previous popes were buried in three coffins: one of cypress, one of lead and one of oak. Francis requested to be buried in a single wooden, zinc-lined coffin and not to be placed in an elevated bier as other popes were.

The coffin will be taken from St Peter’s Basilica and placed on a dais in St Peter’s Square, where Cardinal Giovanni Battista Re will lead the service. After the service, the coffin will return to St Peter’s Basilica before it is carried across the River Tiber and to the Papal Basilica of Saint Mary Major for burial. The ceremony is estimated to end around 2 p.m. local time, or four hours after it begins.

Pope Francis’ funeral Mass will be the first of nine Masses held daily at St. Peter’s until May 4. This is an ancient tradition of the Catholic Church that observes nine days of consecutive mourning. According to Vatican News, a different group of mourners will participate each day, though the Eucharistic celebrations are open to everyone.

Who will attend Pope Francis’ funeral?

Hundreds of people, including world leaders and royals, are expected to attend Pope Francis’ funeral.

US president Donald Trump confirmed on his Truth Social Platform that he and first lady Melania Trump will be at the funeral. This will be Trump’s first foreign trip in his second term. He is expected to have a seat in the third row, though the Vatican has yet to release an official seating chart. It is tradition for the first row of seats to go to Catholic royalty, and the second row to non-Catholic royals.

Prince William, who is attending on behalf of King Charles, will sit in the second row, which is reserved for non-Catholic royals. Former president Joe Biden and first lady Jill Biden, devout Catholics, will also attend the funeral.

Conclave: What happens next to choose the new pope

After Pope Francis’ funeral, the cardinals of the Roman Catholic Church will vote on his successor in an assembly of cardinals known as a conclave.

There are many matters for the cardinals to settle before the conclave begins, but once it does, it can take days or even weeks to conclude. Two-thirds of the cardinals’ votes are required to elect the next pope. The conclave occurs behind closed doors and the vote tally is never made public.

Look for the white smoke

The ballots are burned after each round, and chemicals are added to the flames to produce black smoke if there’s no majority. When a new pope has been selected, the chemicals will be added to the flames so they produce white smoke. Crowds gather in St. Peter’s Square to watch for the results.

If you’re fascinated by the process, you can watch a dramatized version of the events in 2024 film Conclave.

In the movie, Ralph Fiennes stars as Cardinal Thomas Lawrence, who spearheads the election of the next pope while investigating rumors about potential candidates. The film is based on the 2016 novel by Robert Harris and is completely fictional — though it does represent some of the events of how actual papal conclaves take place. In March, the film won the Academy Award for best adapted screenplay.

You can stream Conclave on Amazon Prime Video, or rent it for $6 on Apple TV, Fandango at Home, YouTube or Google Play Movies.
