Prusa Unveils New Mini three-D Printer, Shakes Up The Competition

For the final couple of years, shopper desktop three-D printer possible choices within the below $1,000 USD vary have fallen into two huge classes: the whole lot bellow $500 USD, and the newest Prusa i3. There are a number of first rate printers made by means of firms equivalent to Monoprice and Creality to choose between on that decrease finish of the size. It wasn’t a luxurious everybody may justify, however when you had the finances to swing the $749 for Prusa’s i3 package, the selection become glaring.

Of path, that used to be ahead of the Prusa Mini. Available as a package for simply $349, it’s a long way and away the most affordable printer that Prusa Research has ever presented. But this isn’t only a few rebranded {hardware}, and it doesn’t compromise at the beliefs that experience made the corporate’s flagship system the de facto open supply FDM printer. For lower than part the price of the i3 MK3S, you’re now not handiest getting many of the better printer’s highest options and Prusa’s famend buyer improve, however even functions that probably gained’t make it to the i3 line till the MK4 is launched.

Josef Průša used to be readily available to formally unveil his newest printer on the 2020 East Coast Reprap Festival, the place I were given the risk to rise up shut and private with the diminutive system. While it may well be awhile ahead of we will be able to do a complete evaluation at the Mini, it’s secure to mention that this small printer goes to have a large affect at the entry-level marketplace.

A Simplified Design

Considering the large worth drop, you may be expecting the Prusa Mini to have got rid of lots of the options that made the new entries into the i3 circle of relatives so widespread. But for essentially the most phase, the Mini will have to ship roughly the similar enjoy Prusa homeowners have come to be expecting.

The Prusa Mini makes use of a 3:1 geared Bowden extruder

That way automated mesh mattress leveling by means of inductive probe, a magnetic spring metal print mattress (in each clean and textured variants), near-silent operation due to the Trinamic stepper drivers, out of the field improve in PrusaSlicer, and the self-checks and security measures that a long way too continuously are lacking on lower-cost printers.

Of path, there must be some cuts someplace. For one, the Prusa Mini does away with the sensor (even though it’s to be had as an possibility) that pauses the printer if it runs out of filament. This used to be one of the important thing upgrades made within the i3 MK3, and is undeniably a pleasing characteristic to have on lengthy prints. But making an allowance for how few different printers even be offering this capacity, the truth that it doesn’t come usual at the Mini definitely doesn’t put it at an obstacle. The indisputable fact that it’s even to be had as an authentic possibility and now not one thing you need to Mod in combination your self is in reality an development over different printers on this worth vary.

To cut back weight, the Prusa Mini additionally switches from an immediate pressure to a Bowden genre extruder. Again, this isn’t in particular peculiar at this worth, and could be very paying homage to the association used at the Monoprice Mini. But it is going to definitely be an adjustment for Prusa homeowners which might be used to an immediate pressure extruder. For instance, Bowden extruders have a tendency to be quite extra finicky and are notoriously tough to get operating with versatile filaments. Incidentally, the transfer to a Bowden extruder additionally way the Prusa Mini isn’t suitable with the corporate’s Multi Material Upgrade (MMU).

Finally, it’s price noting that the Prusa Mini forgoes an built-in energy provide and as a substitute makes use of a laptop-style “energy brick”. While a quite unglamorous exchange, this isn’t more likely to be a deal-breaker for somebody. But definitely one thing to imagine when considering of the place you’ll put the system, or when designing an enclosure for it.

Printrbot referred to as, they would like their energy provides again.

Now You’re Playing with Power

While the mechanical facets of the Prusa Mini were simplified in comparison to its better predecessor, the electronics have long past in the wrong way. At least in that appreciate, the brand new printer is in reality rather just a little extra complex than the i3 MK3S. It stands to reason why that the Mini will function one thing of a check mattress for the electronics that may cross into the following era of Prusa printers, so potential consumers could be smart to be expecting some rising pains.

The show is shiny and simply visual from a distance.

The Mini options an absolutely made over regulate board and accompanying person interface. The new 32-bit ARM STM32F407 provided “Buddy” controller is hugely extra robust than the 8-bit board Prusa makes use of within the i3, and because of its onboard Ethernet and USB, can carry out the entire duties you’d recently must do with a Raspberry Pi operating OctoPrint.

Or a minimum of, it is going to at some point. Prusa says the ones extra complex options, together with webcam improve, are coming down the road as a device replace. Speaking of which, the Buddy board is in a position to pull its personal firmware updates down over the Internet; so not more plugging it into the pc to manually flash the newest hex report. With the DIY addition of an ESP module, it’ll even be capable of do this over WiFi.

Increased computational functions within the controller additionally permit some quite flashy graphics at the printer’s 2.8 inch LCD. Not handiest does the 320×240 display screen glance worlds higher than the i3’s relatively dated show right through standard operation, nevertheless it lets in for three-D rendered previews of the chosen STL. Users will be capable of visually verify what they’re about to print, relatively than having to bear in mind the report title of a specific object.

Though for the entire new functions of the Buddy board, there may be a minimum of one omission that long-time Prusa homeowners would possibly in finding extraordinary: there’s no improve for SD playing cards. STLs are actually loaded both over the community or from USB Mass Storage. Arguably that is an development, however nonetheless quite surprising for the reason that just about each and every desktop three-D printer for the reason that MakerBot Cupcake has had an SD slot.

A New Member of the Family

One factor made abundantly transparent used to be that the Prusa Mini isn’t supposed to compete with the i3 line, a lot much less serve instead for it. Josef Průša says that the i3 MK3S remains to be going robust, and can proceed to be up to date as time is going on. He additionally says the staff is operating on a brand new CoreXY printer codenamed “Prusa XL”, however that we’ll have to attend till subsequent yr ahead of we see the rest concrete on that one.

The Mini is envisioned as an excellent starter printer, or in all probability at the same time as a secondary printer so you’ll be able to get started tackling large jobs in parallel. Prusa says its small dimension and built-in far off regulate functions additionally make it an excellent selection for print farms. Whatever folks might be purchasing them for, at this worth, we predict the Prusa Mini goes to be in prime call for for the foreseeable long run.
