Print Speeds

There is a marketing war with 3D FDM printer makers of who can advertise the fastest printing machine.  Within the last year, the brag print speed has moved from 100 mm/s, to 300mm/s, and now to 600 mm/s.

Acceleration has leaped from 1,000 mm/s^2 to 20,000 mm/s^2

There are practical and physical limits on how fast hot melted plastic can flow from a pin-hole size orifice and be deposited in multi-layer, super thin layers. At the same time producing the highest quality practical printed item.

Activity Cetus2 Snapmaker J1


Been cranking hard printing on my two newest 2 filament printers. The Snapmaker J1 and the Cetus2. Best of both flavors, IDEX and single nozzle.

Neither, do I consider perfect a printer. Once I learned their individual weaknesses and work with their strengths, it has been all production and fun. Use them properly and 2 color FDM prints are very nice.

The Real Story of SMJ1

The Snapmaker J1 is not a perfect IDEX 3D printer, but it is a very good one. That’s my personal opinion.

Online and FaceBook user forums are available and have a lot of interesting threads (stories) of user experience. But forums are not a good place to seek service or repairs when something goes wrong. Highly experienced people like myself soon tire of the rhetoric and misunderstanding of the hardware functions, and limited understanding is clearly displayed in most non-qualified user postings.


The Quantum Domain

The smallest common denominator when reducing anything to the basic truth, resides in the Quantum Domain. Where nothing is as simple as it seems.

It’s why I can blame Quantum Mechanics when something goes wrong with one of my three dimensional prints. I know I probably overlooked a higher dimension. My reality becomes entangled.

I discovered my primary method of digital communication (email) sometimes seems to operate in a new dimension. Attracting very strange offerings from spooky creatures beyond an obvious 3 axis environment. Somewhere really “FAR OUT!

I created a new email organization I call ““. It’s not a website. It’s an email domain. I use it to communicate instantly, anywhere in the universe. It works for me.

Don’t get too alarmed if you see one of my emails from my favorite email domain. ~DK



Hear the beat of the drums. Bongo drums. I wonder if it is a bongo drum or because there are two it should be plural? I think its a Bongo drum because the male and female (That’s what they are called) drums are joined as one and sometimes just called Bongos.

If I made two sets, then I would have Bongo drums.

I have an adult son, Steven. He is a professional class percussionist and started playing about 45 years ago. He presently has a huge drum collection. I bet he doesn’t have a set of baby Bongos. 


Speed VS Quality

I recently ran a small test with one of my Cetus printers. Speed against quality. No doubt (again) that high speed and best quality do not hold hands. 

I am saying “best” quality. High speed and “acceptable” are friends, they get no where close to “best” quality.

Printing FDM at high speeds is much improved with the new hardware I have seen released in year 2022. But the results are still not in the best category.
