Prusa releases updates for Authentic Prusa i3 MK3 and SL1


Prusa Exploration, an award-winning Czech 3D printer and filament maker, has announced the hottest updates to its components and program.

Composing for the official Prusa 3D printers group, Josef Prusa, the founder of Prusa Investigate, claimed, “Some time in the past we did a significant study about our merchandise and it was immensely useful. I want to thank everybody who participated. Constructive criticism is the finest point we can would like for and it served us shape the current items of MK3S and MMU2s.”

Prusa also explains, “We have been developing as speedy as at any time, and we by now attained the incredible milestone of 100,000 3D printers delivered! Just in January, we dispatched 14,000 orders (not all of them are printers).”

Smoother extrusion

Prusa Exploration is regarded for its open up-resource First Prusa i3 MK3 3D printer, elements of which are manufactured in a enormous 3D printer farm housing a few hundred Prusa i3 MK3s.

Just after a consumer study, Prusa Study has redesigned the extruder for the Unique Prusa i3 MK3S package. The extruder now has a new optical sensor which can detect filament owing to a mechanical lever attached to the sensor.

Prusa explained, “The new sensor is employing the optical sensor which is activated by a simple mechanical lever. This sensor doesn’t care about the optical homes of the filament (it can be entirely invisible) and are not able to die because of mechanical don.”

The Prusa person local community also instructed that servicing the extruder really should be a lot more practical. As a result, the new extruder is built in such a way that nozzle or PTFE tube can be changed with out disassembling the extruder.

“The MK3S includes all the cumulative upgrades from the entire everyday living cycle of the MK3. Right before the launch, we have produced a number of enhancements – like working with authentic Gates belts, we also replaced the spiral wraps with textile sleeves, developed a new Einsy case, extra an anti-rust coating on clean PEI sheets (a lot more info below) and, of course, there are dozens of firmware and plastic parts enhancements.”

Multi substance 3D printing certification

Very last year Prusa Study released the Multi Material Improve 2. (MMU2) for the Authentic MK3. This improve kit lets user print with five distinct filaments enabling shade 3D printing certification as properly. Nevertheless, it seems that the user opinions for the MMU2 upgrade has not been all constructive. Problems with filament tangling and filament reloading have been documented by the end users.

Prusa wrote, “The consumer study confirmed that the prior current spool holders perform thoroughly if the filament guides are eliminated and the spools are positioned much ample from the printer. Regrettably, it took a ton of house.”

“The tangling of the filament when unloading was a tougher nut to crack but we solved it by having a different buffer which consists of the unloaded filament.”

The reloading mechanism has been mounted by earning confident that the redesigned MK3S extruder is capable to perception that the filament has touched the Bondtech gears.

To evaluate the MMU2 deal with, in excess of a two-month period, Prusa Research 3D printed 478 exam blocks. These blocks assessed the efficacy of recurrent filament improvements. Twenty 3D printers have been used for this job with a full variety of filament alterations amounting to 600,000.

The greatest detail about the newest MMU2 improve is that “every latest owner of MMU2 will be obtaining the up grade to the MMU2S (self-printed areas for the extruder up grade) for free no issue in which in the entire world you are.”

Finally, new firmware for the MK3S/MK2.5S (model 3.5.3) are also becoming launch which will also improve the functionality of the MK3 and MK2.5 (3.5.2).

“One of the standouts is a distinctive method for controlling the heatbed electric power which reduces the PSU clicking noise.”

SLA printer by Prusa

Very last yr, Prusa entered the SLA/DLP market and launched the SL1 SLA printer. Issues noted with the SLA printer have now been solved.

The major situation with the SL1 was that the exhibit display screen cracked when printing large types. With most areas of the screen now changed this issue has been preset. Additionally, the tilting system has been modified to minimize the stress from the screen.

Z-axis precision has also enhanced, “We modified the supplier of rods and added a second spring to the Z-axis motor. Z-axis precision is now guaranteed and print good quality is fantastic,” wrote Prusa.

In addition to the significant updates Prusa also noted some slight updates which involve an enhanced textured mattress plate sheet, updates to the Slic3r PE, and print profiles categorized dependent on ‘quality’ and ‘speed’.

Finally, Prusa Analysis is also operating on a documentary on how the corporation arrived out of the basement to capture the 3D printing certification market.

Nominations for our 3D Printing certification Marketplace Awards 2019 are open up. Title the greatest 3D printer now!
