New Matter's MOD-t 3D printer on sale for $399

A couple of weeks ago I reviewed New Matter's MOD-t 3D printer. It was $400 at the time, but the price has temporarily dropped to $340. This is a great deal for an excellent 3D printer. I've been using mine like crazy since I got it. Read the rest

3D printers needed to crowdsource a giant Rosie the Riveter

Todd writes, "We the Builders brings together 3D printer operators from all over the world to create sculptures that inspire makers. Our sculptures have toured maker-related events of all sizes around the northeastern United States, from local STEAM education events all the way to the White House. They are crowd-sourced, made up of hundreds of pieces 3D printed by people like you, and then mailed to Baltimore." Read the rest

Using my 3D printer to fix broken stuff around the house

I'm slowly getting the hang of using my 3D printer to make useful things. Last week, I made sliders for the legs on our pool chairs. This weekend, I made a doohickey to hold our freezer's ice cube container lid in place. The container would often crash to the floor when the freezer door was opened because a plastic hook had broken off. It took me a lot of trial-and-error to make this little doohickey (my failed prototypes are in the picture below) but once I arrived at a solution that worked, it felt good!

If, for some reason, you want the 3D model, I put it on Thingiverse. Read the rest

I finally 3D printed something useful

We have two 30-year-old poolside chairs. They might be 40 years old. They are excellent metal chairs with adjustable backs. The problem was that the plastic sliders on the bottom of the legs had long ago disintegrated, leaving nothing but bare metal. So, when my wife or kids dragged the chairs across the concrete, the legs would make a brain-curdling screeching sound. I had been thinking about making wooden plugs to stick into the hollow legs like corks, but then I realized I could easily make custom sliders with my 3D printer. Read the rest

The $100 Peachy 3D Printer is amazing

$100 buys you a snap-fit 3D printer. Whitney Hipolite of says the resin-based Peachy Printer is "amazing."

One of the great things about the Peachy Printer is that since it is only available in kit form, it can can be completely customized to the size you want. The build volume can be modified depending on the size of an object you need printed, and even the color resins can be mixed in order to create new colors. Want a yellow-green color? Then mix the perfect amount of yellow and green. Peachy Printer will offer 8 completely mixable colors.

Makerbot announces three new 3D printers, including a massive 47.5cm tall monster

Yesterday at CES, Makerbot CEO Bre Pettis announced three new 3D printers, including a massive, fifth-generation Replicator capable of producing objects that are 45.7cm tall and 30.5cm wide/long. Interestingly, all three new models -- there's also a simple, one-button version and a desktop prosumer version -- sport clear plastic sides. 3D printers are very susceptible to disruption from even slight breezes (the wind cools the plastic between the nozzle and the previous layer) but there's a completely batshit patent on the totally obvious "invention" of putting see-through sides on a 3D printer, so in general printers don't ship with sides, and manufacturers don't publicly advise their customers to add plastic sides to their machines.

Engraving a Klein bottle with an Eggbot

The Evil Mad Scientists were presented with a challenge: inscribe one of Cliff Stoll's hand-blown Klein bottles, an object of surpassing beauty and odd topology. They modified an Eggbot plotter to etch the surface of a Klein bottle with a diamond engraver attachment. Read the rest

Scratch-building a keyboard

When Jesse Vincent's boss stole his beloved keyboard, it set him on a long journey to make his perfect and ideal keyboard from scratch (ish -- he bought the keycaps premade). This slide deck documents nine generations of scratchbuilt keyboard prototypes. Vincent is now planning a Kickstarter based on his experiences, making some kind of custom keyboards for the world.
