    Choosing Filaments for First Time 3D Printing

    One of the first questions a person new to 3D printing has to sort out is what kind of filament to use. The novice is presented with a large number of choices, all with three-letter-acronyms (TLA’s). The most common filaments are PLA (Poly Lactic Acid), ABS (Acrylonitrile butadiene styrene)...

    Conductive filament for 3D printers

    I'm curious to know if anyone has played around with the conductive filament that Proto Pasta has available? Electrically Conductive Carbon PLA Composite – ProtoPlant, makers of Proto-pasta While probably not good enough to route a PCB due to resistance, it seem to offer a very interesting...

    What do you use for 3D CAD?

    I'd be curious to know what people are using for 3D CAD for their 3D printers. I know that Fusion360 is getting traction. I found a lot of the low end free programs to be too simple for the things I wanted to make. I used Sketchup for a while, but the lack of parametric capabilities limited what...

The ~$300 price tag made getting one a simple choice. But I took on the risks of supporting a kickstarter - there is no guarantee...

    Milling machine or 3D printer?

    I bought a micro milling machine before I bought a 3D printer. I did this because I wanted to mill my own PCB's. The milling machine, made by Other Machine Company (Home) also allows me to precision cut materials such as soft metals, wood, plastic, etc. I am about to get my first 3D printer...

    3D printing for home or industry?

    I am waiting for my first 3D printer to arrive in March. I contributed to the Kickstarter for Micro3D, a $350 3D printer for home use. But it seems that the bigger push in 3D printing will take place in industry. I've see announcements from HP on a 3D printer for commercial use. But by far the...

    Raspberry Pi 2 announced - 6X faster processor, same low price

    Yesterday I saw that the Raspberry Pi Foundation announced a new version of their popular Raspberry Pi board that runs 6x faster than the previous version. It now uses a quad core 900 MHz ARM A7 core built by Broadcom. It also has 1GB SDRAM. And is fully compatible with the previous version of...
