The Potential Revival of Slower 3D Printers: Transforming from ‘Junk’ to High-Speed.


There is a fascinating implication that arises from the achievement of high-speed printing on the Prusa Mini. The world of desktop 3D printing is now being dominated by high-speed 3D printing. Thanks to the introduction of vibration compensation, also known as input shaping, desktop 3D printers can now operate at much higher print speeds. While typical 3D printers run at speeds between 40-80mm/s, those with the new feature can reach astonishing speeds of up to 600mm/s under certain circumstances. This means that prints can now be completed 3-5 times faster.

Having recently used a series of high-speed devices from various manufacturers, I have been truly impressed by their capabilities. The prints now finish in such short durations that it almost feels like something out of science fiction. However, there is a downside to experiencing these rapid print speeds. Once you get accustomed to the convenience and efficiency of completing a print job in just a few hours, it becomes difficult to go back to using slower printers.

Looking around my workshop, I can’t help but view my “slow” 3D printers as obsolete. They are perfectly usable machines, but the fact that they take so much longer to complete a print makes them unappealing. It seems that many others might share this sentiment after experiencing high-speed desktop 3D printing. We are headed towards a world where these slower printers will become obsolete and eventually be discarded.

But perhaps there is another way forward. Prusa Research, in an attempt to catch up with Bambu Lab’s ultra-fast devices, has introduced the MK4, which is touted as a high-speed machine. However, the firmware that truly enables high-speed operations has not been officially released yet. Interestingly, they have managed to port their high-speed firmware onto their smallest machine, the Prusa Mini. This experimental firmware is now available for download at no charge, allowing Prusa Mini operators to upgrade their machines and enjoy supercharged printing speeds. It’s worth noting that this firmware is still in the alpha stage, so users should exercise caution.

This development got me thinking about all those “junk” 3D printers I mentioned earlier. If Prusa Research can resurrect one of their basic printers with advanced firmware, then couldn’t the same be theoretically possible for other desktop 3D printers? The conventional wisdom suggests that random printers wouldn’t be capable of high-speed printing due to their mechanical systems not being robust enough to handle faster motions and rapid momentum changes. Consequently, high-speed operations have thus far been limited to new machines with suitable motion systems and rigid frames.

However, the Prusa Mini defies this conventional wisdom. It is a cantilever design, offering far less rigidity compared to typical bed-slinger style printers. If Prusa Research can make the Mini print significantly faster through firmware upgrades, it should be feasible to do the same for most other printers. But will other manufacturers follow suit, like Prusa Research, and offer free firmware upgrades for their older printers? Or will they simply release new high-speed machines in the hopes of generating sales? My suspicion is that most companies will choose the latter, meaning we shouldn’t expect widespread availability of high-speed firmware upgrades from manufacturers.

This leaves the task of firmware upgrades to third-party providers and individual DIY operators. The DIY community is resourceful and will likely find ways to install Klipper or similar high-speed firmware on their older machines. However, there could be a potential business opportunity for someone to develop packaged high-speed firmware upgrades for various older machines. Considering the millions of slow printers currently in use worldwide, many of which are likely capable of high-speed printing, there could be a viable market for such upgrades. Machines like the Prusa MK3 and the Creality Ender-3 are widely adopted, making it financially feasible to cater to this demand.

In conclusion, the achievement of high-speed printing on the Prusa Mini has opened up new possibilities and implications for the world of desktop 3D printing. While this development may make older, slower printers seem obsolete, it also presents opportunities for firmware upgrades and the potential for a new business niche. As the industry evolves, it will be fascinating to see how manufacturers and the DIY community adapt to the demand for high-speed printing and whether older machines can be revitalized through firmware updates.
