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 […] 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 […] Continue reading » Junque Plastic

All Things Plastic?

Feeling rooked?

I am writing this as I think the “blush” of a new love has worn off. The love was infatuation with the process of three-dimensional printing. I truly like using the process but now only for purposes where it makes real sense. Printed plastic parts have a place in many things I like to make. That’s not going away.

I have also made a huge box full of useless plastic junk just because it was possible. Yes, it was fun. But it is still useless junk. I gave most of it to my young granddaughter as “toys” to play with. […] Continue reading » All Things Plastic?

The K0BSR Ring

I was contacted by email from an amateur radio operator, Ben K0BSR, in Colorado. Hams reading this will know how to find out more about him.

He saw my silver work and wondered if I could make him an amateur radio callsign ring. I have made several versions for myself and my own radio call sign.

I asked him for suggestions and he came up with the idea that he wanted it to look like a portable HF radio. That seemed like a good design challenge for me.

I have been playing with three-dimensional printing and thought this was a great project to create […] Continue reading » The K0BSR Ring

3D Printing, Not for Everyone

Merry Christmas!

I am amazed by the number of people attempting 3D printing. It’s a wonder, and a curse. Or perhaps I should say causes a lot of wondering, curses and cursing.

I am afraid that because of the reduction of cost, 3D printers are a popular holiday purchase. Many will be in the hands of totally inept owners who expect a plug-and-play experience.

Plug and play (P&P) may be possible on some brand-new units, but in the long term, 3D printing is very far from P&P. A keen aptitude for observation and trouble shooting is a major requirement. The […] Continue reading » 3D Printing, Not for Everyone
