I got my kit and am assembling it. I am taking longer than the estimated 3 hours, but I want o make sure I do it correctly.

I have gotten most of the extrusion parts assembled plus the frame. I have done all the loose precision stuff and now I have to adjust more precisely, as I add the motors and do the final assembly.

Overall not too bad so far.

Hey, someone else that appreciates the smelly effectiveness of Static Guard! lol

I decided to add an LCD panel to it. The kit came with the LCD mount included even though I didn't buy and LCD at the initial point of sale.

The vendor wanted 45 bucks after market for the smart LCD but amazon had it for 15.

It took some work to install because some of the pins weren't cut, so I dremelled out the back of the wood to get the lcd to fit flush ( i didnt want to cut the pins).

Once it was mounted and connected, the backlight turned on, but no display. I updated the controller firmware, and restarted. No display. I started messing with the configuration options in the firmware source. No display.

Two hours later, I looked at the back of the lcd pcb, and there was a tiny screw. Labeled "Contrast."

d'oh.

Works great now.

I just tried printing with thermoplastic polyurethane (TPU). It produces a flexible object similar to rubber.

Feeding it is a pain because the filament is flexible and buckles with any resistance. I finally got my printer calibrated and I am going to attempt a iPhone bumper this weekend.

It's amazing some of the different materials that are coming out for 3d printing applications.

Startup 3-D prints house in hours for a fraction of average home cost

It costs about $237,000 and about three to six months on average to build a home in the United States, but crews in Austin, Texas, say they've figured out a way to build a house in less than two days for a fraction of the cost.
"This just isn't – isn't a technology that's gonna help a little niche of the way we think about shelter, this is a paradigm shift in the way we build houses," Jason Ballard, the co-founder of Icon, one of the companies behind the project, told CBS News' Omar Villafranca.

The technology starts with a one-ton, 3-D printer, which squeezed out enough concrete to build a small, two-bedroom, one-bathroom, single-family home.
"It's a house-printing robot," Ballard quipped.

"So this house right here was printed in 47 hours at quarter speed.... At full speed, could have printed this house in 11 or 12 hours," Ballard said. "And that's on version one of the technology."
Brett Hagler runs a nonprofit called New Story. He's hoping to bring the technology to poor communities in El Salvador by the end of next year.
"It's designed to take families that have been living in tents or shacks and to bring them into what we believe is a beautiful home that they can build their lives on for the next few decades," Hagler said.
University of Texas Engineering professor Raissa Douglas Ferron is an adviser on the project. While she sees the potential for 3-D printed homes, she questions how the concrete mix will stand up over time. She said there's not enough data yet to say whether these kind of homes can be safe, but believes they need to be built in order to collect that data.

"If we wait until there's data in order to build it – you're never going to build it," Ferron said.

Icon will use the model home as an office for the next few years while third-party labs test its long-term durability.
"We're gonna make ourselves the guinea pigs before we put another family's life in the mix," Ballard said.
The design does have limitations. Utilities like electricity and plumbing still need to be installed outside the walls. Even if all goes as planned, it will likely be years before 3-D printing becomes a mainstay of U.S. residential construction.
