New Authentic Prusa MK4S 3D printer takes ‘cool’ to 360° | VoxelMatters

Czech AM firm Prusa Analysis has launched its newest 3D printer for the desktop market: the Authentic Prusa MK4S. The brand new system introduces options like 360° cooling, a high-flow nozzle, a brand new Prusa app for distant monitoring and firmware updates for quicker printing speeds. The system, now obtainable, is being offered as both a completely assembled plug-and-play system ($1099) or as an meeting package ($799). For current homeowners of Prusa’s quickest promoting 3D printer, the MK4, an improve package for $99 can be obtainable by the tip of the month. With out additional ado, let’s leap into all of the updates and enhancements that the Authentic Prusa MK4S 3D printer provides.

360° cooling

One of many key enhancements to the Authentic Prusa MK4S is a very redesigned cooling system. Particularly, the machine integrates a fan with high-performance 360° cooling that unlocks quicker printing with out sacrificing high quality. The upgraded cooling system additionally permits the extrusion of steep overhangs (as much as a 75° angle) with none helps. As Josef Průša, founding father of Prusa Analysis, stated: “We spent a very long time searching for a brand new fan that will substitute the present answer. This was fairly difficult, because the cooling on the MK4 was already superb, and there was a protracted listing of necessities to satisfy (weight, strain, noise, PWM, and extra) if we needed a brand-new print fan.” In the end, an answer was developed from scratch, leveraging a high-pressure turbine and redesigned fan shroud mounted on the extruder.

“Its place is exactly calculated in order that it doesn’t quiet down the nozzle or blow the recent air again towards the heatsink,” Průša added. “As at all times, we went somewhat additional than what was wanted – the brand new turbine is highly effective sufficient to run at 60-70% of its max velocity more often than not (it goes to 100% solely in particular conditions), so it’s nonetheless very quiet whereas delivering a lot larger efficiency in comparison with the previous mannequin.”

Excessive-flow nozzle

The MK4S additionally integrates a high-flow nozzle designed by Prusa Analysis and based mostly on CHT know-how. This high-flow nozzle, which comes commonplace on the brand new 3D printer, can be utilized with all commonplace filaments and might obtain volumetric movement charge will increase between 45 to 114%. “A high-flow nozzle primarily allows you to print quicker as a result of the fabric contained in the nozzle can be melted quicker (and higher) which ends up in improved volumetric movement,” Průša defined. “If you wish to print quick, it’s not nearly shifting the extruder quicker, however you additionally must get the filament to its optimum melting level, in any other case, the print can be completed quick, however the interlayer adhesion can be extraordinarily poor.”

That is attainable because of the high-flow nozzle, as could be seen within the knowledge provided by Prusa Analysis evaluating the volumetric movement of a normal 0.4 mm nozzle and the Authentic Prusa MK4S high-flow nozzle with identical diameter:

The high-flow nozzle together with firmware updates lead to a 3D printer that’s considerably quicker than its predecessor, whereas additionally reaching superior print high quality. In response to Prusa Analysis, the updates make the brand new system on par with the quickest extrusion 3D printers in the marketplace.

Prusa app

Alongside the brand new {hardware}, Prusa Analysis has additionally developed and launched a brand new app for iOS and Android which facilitates distant print administration and print monitoring. The app, which could be arrange utilizing the 3D printer’s Wifi and an NFC faucet, permits customers to handle a number of 3D printers without delay, visualize energetic duties, and begin, pause or cease prints from distant areas. The Prusa app additionally offers customers direct entry to Printables, and permits for one-touch printing with out the necessity for slicing.

We have now a model new native iOS and Android Prusa app for print monitoring and distant print administration permitting you to print tasks instantly from Printables with out utilizing a slicer. The app is already obtainable in respective app shops and it additionally brings one other helpful function – you’ll be able to merely arrange the printer’s Wi-fi with an NFC faucet. The app is non-obligatory and is suitable with the MK4S in addition to all different Prusa Join-compatible 3D printers. In response to Průša, we must always anticipate updates and new options for the app, together with digicam help, superior notification settings, widgets and extra.

Extra options

In true Prusa Analysis style, the brand new MK4S system is open to consumer mods and hacks and even comes with  non-obligatory equipment for superior customers: a GPIO hackerboard and an accelerometer add-on. “This small electronics board connects on to the mainboard and you may management it utilizing G-code instructions,” Průša writes of the GPIO hackerboard. “So, for instance, you’ll be able to solder an LED strip to it and let it flash in particular colours when a print is completed. You too can arrange a distant digicam set off, activate filtration, or design your individual print harvester. The chances are just about infinite and we will’t wait to see what loopy concepts you’ll provide you with!” The accelerometer, for its half, is an non-obligatory accent that permits guide calibration for customers that make drastic adjustments to their MK4S 3D printer.

In the end, all of the upgrades to the brand new system translate to a 250 × 210 × 220 mm desktop 3D printer able to printing at quicker charges and with superior high quality. To exhibit the upper high quality of the Authentic Prusa MK4S, Prusa shared a graphic evaluating a MK4S print to a competitor’s print. Inexperienced signifies the place dimensional accuracy is highest, whereas the yellow and crimson areas determine the place there are inaccuracies.
