My 3D Junque Factory

Not MY Plastic!

I have taken a serious look at hobbyist level 3D printing. Two kinds of hobbyists. The ones tinkering with the hardware and software (firmware) still stuck in the RepRap phase (and loving it!) – building a “better” machine that can build itself. The other hobbyist is the plastic Junque maker (like me) printing tons of plastic on Chinese made hardware. 

No US manufacturer of 3D printers can really compete (in price) in the base hobbyist market with US made hardware. Printing Hobby Junque doesn’t make sense using a $2500 to $10,000+ commercial US machine.

Perhaps a few deep pockets may go there.

As a […] Continue reading » My 3D Junque Factory

Seizure Research

I thought researching something as mundane as what type of anti-seize compound would be proper for my 3D printer nozzle would be an easy task. What I found was a few standard ingredients for a variety of applications. But then a very poor (meaning non-specific) explanation of how, when, where each “blend” of materials should be selected.

What this indicates is not many makers of the anti-seize material have taken the time and effort to publish (on the internet) a substantial product selection guide. It may exist but it is just been difficult for me to discover with a  key word search.

Suffice to say, I did find enough […] Continue reading » Seizure Research

Little Mama Cetus

Little Mama Cetus

Sheee’s Baaack!  Mama Cetus has been replaced courteous of my insurance. Original MamaCetus got fried in the lightning strike. Since the first was called “MamaCetus” and the second named “BigMamaCetus” (BMC) (as she was equipped with all the features), the new arrival has been dubbed “LittleMamaCetus” (LMC).

LMC is nearly an exact copy of MamaCetus, a MK1 version. LMC is a MK3 basic and the only real difference is LMC has travel end switches rather than stepper motor stall “home” sensing. It has the original style extruder, which is good as I have a collection of new […] Continue reading » Little Mama Cetus

Last Strike?

Thought I found all the lightning damage. Not so… 

I knew the power supply for the older Cetus 3D printer was burned out. Zero voltage output. I needed a new power supply to test the printer. I have two Cetus 3D printers as shown in the pictures, but their power supplies are very different.

The newer printer on the left has a much higher wattage supply than the one that has failed on the right and a different plug. I had to order a new power supply for the right-hand printer as it was definitely dead, with zero output.

The replacement power supply came today all […] Continue reading » Last Strike?

Creative Manufacturing Art and My Personal Philosophy Best of Both

I have one outstanding way of creating wax masters for lost wax casting. I use a high-speed spindle (up to 25,000 RPM) on a Taig Micro Mill. If I can draw it properly, I can machine it in 3D.

The limitation is the 4-axis ability of this machine. That doesn’t sound like much of a limitation to most machinist. 4 axis means X, Y, Z movement with an additional rotary A axis. There is a huge amount of work that can be accomplished with 4 axis milling.

But there are some designs that can benefit from additional movement freedom. […] Continue reading » Ramblin’ On
