Snapmaker J1


I really have a workhorse 3D printer in my Snapmaker J1s. It’s an independent dual extruder FDM printer with a build area of 210x324x200 mm. Extruder temp range is up to 300 C and the bed is good to 100 C. That provides the ability to print a wide range of materials. As you can see in the picture, it is also totally enclosed. 



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. 


Why 0.40mm?

Quantum mechanics makes me look at things in new ways. A recent browse through current topics on 3D printing revealed some pundits are questioning how in FDM printers, did 0.40mm nozzle become so dominate with the 1.75mm filament.

I am not going to explore the reasons here. Best to say, for the typical size prints made by hobbyist, it is a very good choice. It works very well.

That is not saying it is the one and only good option. 


Bowden Worm Hole

Just finished a lot of Print testing with my Anycubic Vyper Bowden tube FDM printer. As I suspected much of the pros and cons about bowden tube systems and retraction issues is pure misinformation or speculation.

Some of the “gospel” may have been true years ago when systems were built up from available tube ID materials. But I have proved to my own satisfaction most of todays machine are built for purpose with correct hardware.


Monster Math

I was working in the quantum-lab, late one night
When my eyes beheld an eerie sight
For my 3D models from their slabs, began to rise
And suddenly to my surprise

I did some math, I did some monster math
The monster math, it was a graveyard smash
I did the math, it caught on in a flash
I did the math, was this Junque or a waste of cash?…

Hah! Just a little jest. If you are old enough you will recognize the words,  rhymes, and meter of the lines above.

The inspiration was my constant feeling of always spending too much time and money making plastic Junque. But the reality for me is this is what hobby-class 3D printing is all about.

Quantum Junque?

A little history

Haven’t been playing with Quantum physics for any length of time. But I have thought about it for probably decades. I don’t know if that counts for anything. Probably not. 

So I just invented using quantum physics as a new source of inspiration for things happening when doing 3D printing. There are many quirks and possibly a few quarks when developing science skills involved in 3D printing.
