3D Printing — Ramblin' Dan

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

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?

A20M Repair

The A20M is my Geeetech (brand) dual color 3D printer. I also own and operate a Geeetech A20T which is a triple color 3D printer.

The new dual extruder

The A20M has been an excellent quality printing output. However the dual print head as been a fairly serious issue. I just installed the second replacement printhead so it is now running on its third.

The second head is identical to the first but the third is anodized black (see pictures). Geeetech has not said what is different on the new black extruder. (print head). They do claim it has been improved and I suspect a few internal […] Continue reading » A20M Repair

Junque Plastic

My Plastic Junque Collection

My creative efforts (making tangible art and thingies) are expanding through the world of three-dimensional printing. It’s a new-age process of additive manufacturing. If you don’t yet know what that is, you have been under your rock too long… Ha! Excuse me while I holster my plastic gun…

Three-dimensional printing at my budget level is mostly Fused Deposition Modeling (FDM) which means hot plastic is extruded through a tiny nozzle and drawn (deposited) as a line, one thin layer at a time on top of the last layer. I also do DLP (Digital Light Processing) which prints a full solid layer rather than […] Continue reading » Junque Plastic
