MakerBot says its new print process reduces times and costs by around 30 percent

Brian Heater  
MakerBot’s MinFill arrived quietly last night as a firmware upgrade for existing customers, and the company is already calling it a “big benchmark in speed and widespread adoption of 3D printing.” Many are understandably a bit cautious around such grandiose proclamations from players in this space, particularly when it comes to something as unabashedly unsexy as infill — the support structures inside a model that keep it from collapsing.
At a bare minimum, however, the newly released MinFill setting boasts some potentially impressive numbers. The technology, designed in-house for the company’s Print software, runs an algorithm that determines the minimal amount of material required to create sufficient infill for a model, saving on material and print costs — both major sticking points in the technology’s adoption.
“You can imagine as you print a complex shape, you get a lot of interesting internal geometries that support the shape in the right places,” the company’s VP of Engineering Dave Veisz tells TechCrunch. “The net effect is that it’s going to reduce the amount of filament used and reduce the print time. So, you’re printing less to get your finished product.”
The time and cost savings varies, naturally, from project to project, owing much to different sizes and shapes of objects, but Veisz says the savings to both average out around 30 percent, effectively cutting the amount of material required to print an object by nearly one-third. Really geometrically complex objects, on the other hand, can have savings of upwards of 80 to 90 percent.

Mechanical Xylophoneneilmendoz 
This Instructable will actually show you how to make a mechanical glockenspiel as the keys are metal rather than wood (xylophone is a far better word though featuring very underused letter X). This instrument was a part of The Rock Band, composed of instruments that make music with rocks by throwing them through the air, slapping them and making them vibrate. The project was created at Autodesk's awesome Pier 9 digital fabrication workshop as part of their artist in residence program.
The rock parts of this instrument are the small pebbles that are launched at the keys. However, any small hard object would probably work. The aluminium keys were fabricated using a water jet cutter. If that tool is not available to you, then wooden keys could be used instead provided that the rest of the design is updated to accommodate their design. The xylophone will be controlled by MIDI so it is possible to control it to using most common music composition software, e.g. Logic, Cubase or Ableton.

The Easiest Arduino High Altitude Balloon Data Logger

Spaceshark 
High Altitude balloons are effective tools in conducting experiments and measuring data in the stratosphere. A successful launch can cost less than $200 and give insight and video of how our planet functions.
For hundreds of years, humans believed the Earth to be flat. High altitude weather balloons prove the Earth is in fact round. The idea of high altitude balloons or HABs is to mount a payload on a giant helium balloon. The balloons are then released, flying to heights of 100,000 feet. Once at these altitudes, the balloon pops and uses a parachute to float back to the ground often many miles from where it was first launched. HABs are great vehicles to get footage from the stratosphere, conduct science experiments, and collect data from high elevations.

3D Printer Buyers Guide

Alastair Jennings 
Frustrated with Fused Filament Fabrication? Read our 3D printing troubleshooting guide to the most common 3D printing problems and their solutions.
It’s amazing what your 3D printer can produce. But we’ve all had those infuriating moments when, despite everything, a seemingly simple model just refuses to print successfully.
You’ve checked the model, seen countless others make it without issue, but try as you might it just won’t print. What is it that keeps going wrong?
Here at ALL3DP, we’ve had our fair share of print failures. But the upside to those failures is that we’ve become finely tuned to recognizing and solving many common 3D printing problems.

DIY Carbide Lathe Tools for Cheap

jimustanguitar 
I recently got into wood turning, and I wanted to have a nice set of tools. Most lathe gouges and chisels are high speed steel (HSS), but they require constant sharpening and leave something to be desired. The premium wood turning tools use replaceable carbide inserts that stay sharp considerably longer, but you also pay a premium for them.
Instead of paying around $100 per tool, I set out to make my own. After it's all said and done, I've got $53 dollars invested in two carbide cutting tools, and I've got 6 regular steel chisels and gouges left from the materials that I bought for the project.
Not too shabby - here's how it's done!

Louvável.









3D printed Peristaltic pumpMarco Arduino channel
A peristaltic pump is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained within a flexible tube fitted inside a circular pump casing (though linear peristaltic pumps have been made). A rotor with a number of "rollers", "shoes", "wipers", or "lobes" attached to the external circumference of the rotor compresses the flexible tube. As the rotor turns, the part of the tube under compression is pinched closed (or "occludes") thus forcing the fluid to be pumped to move through the tube. Additionally, as the tube opens to its natural state after the passing of the cam ("restitution" or "resilience") fluid flow is induced to the pump.

Spirograph-Inspired Maker Blasts Kickstarter Goals By 224%, Then 544%

Could a free toy in a package of candy change the trajectory of your life? For Aaron Bleackley, it did. 
It all started one day in early 2013 when one of his coworkers got a tiny geometric drawing toy when purchasing some candy. They passed it around the office and played with it. Never having a Spirograph® set as a kid, Aaron was enthralled.
This kind of drawing toy works using simple gear interaction. Just place a gear in a larger ring and use a pen to rotate the gear around the inside of the ring. The result: A multitude of interesting geometric patterns can be created.
That night, he bought a Spirograph kit. Throughout the next several weeks, he purchased several more geared drawing toys and spent his evenings admiring the beautiful designs that he made with them.
Eventually he became frustrated, however. There was a lack of variety of design options. He wanted more pieces. The plastic from which the pieces were made was fragile and imprecise. And the gears often slipped and hopped out of the rings.
“I scoured the internet for a really good Spirograph but didn’t find anything to satisfy me,” Aaron says. “So I concluded that I would have to make my own.”

Raspi Compute 3! E Colunas Bluetooth em Cabono? Mais Qr Code com o vosso Logo, converter 3D, e cortar com discos... De PAPEL!

A Família Raspberry Py conta agora com este Compute 3, duas vezes o RAM, e quase 10 vezes o desempenho de CPU do Module original!




COMPUTE MODULE 3 LAUNCH!James Adams 
Way back in April of 2014 we launched the original Compute Module (CM1), which was based around the BCM2835 processor of the original Raspberry Pi. CM1 was a great success and we’ve seen a lot of uptake from various markets, particularly in IoT and home and factory automation. Not to be outdone by its bigger Raspberry Pi brother, the Compute Module is also destined for space! 
Since releasing the original Compute Module, we’ve launched 2 further generations of much faster Raspberry Pi boards, so today we bring you the shiny new Compute Module 3 (CM3); this is based on the Raspberry Pi 3 hardware, providing twice the RAM and roughly 10x the CPU performance of the original Module. We’ve been talking about the Compute Module 3 since the launch of the Raspberry Pi 3, and we’re already excited to see NEC displays, an early adopter, launching their CM3-enabled display solution.

Um Forno de temperar metal! E fotos da passarada, uma Serra de Fita portátil, o vosso póprio Aduino Nano, e uma Mega-Lanterna LED

Se quizerem temperar Metal duma forma científicamente controlada, podem agora fazê-lo, a preceito, com um baratíssimo forno de Toradas, e uns truques!
É bom!
Muito importante para obterem peças em Aço com a dureza e flexibilidade que quizerem, molas ferramentas de corte, etc. 






PID Temperature Controlled Oven

kai.h  
With this instructable, we will take a cheap toaster oven and turn it into an accurate, temperature controlled tempering oven that will be able to achieve a stable and accurate temperature controlled by a microprocessor.
We will combine some common and off-the-shelf components to easily and safely achieve this goal.
Why do we want to do this? After heat treating steel, it's in a very hard and brittle state. So we can use it with less risk of it snapping, we want to temper it. Tempering will slightly soften steel, but more importantly will restore flexibility to it. Most steel manufacturers specify particular temperatures to temper steel at so you can achieve a given hardness rating.










Para fotos da passarada do vosso Quintal, enquanto não lá estão, que é quando eles estão à-vontade, contem com esta Engenhoca, que detecta os vossos amigos de asas, e os fotografa, enquanto vão às compras:






Simple PIR DSLR Camera Trap

stinkyabb

The biggest problem I have capturing images of wildlife is not getting close enough to the subject. I never have enough time to sit and wait for them to come to me or they are easily spooked, and fly away at the first sign of movement. Using an simple, widely-available PIR motion sensor, I can leave my DSLR in the yard to capture images while I run errands, cut the grass, or even leave it out overnight.












Uma Serra de Fita que podem levar às Exposições, Trabalho de Campo, Campos de Aero-modelismo, e o mais que queiram, já existe, mas o que fazem com esta adaptação, é terem uma base fixa que vos permite tabalhar duma forma precisa, como nos modelos maiores:







Portable Bandsaw Metal Stand

seamster 
I recently got a portable band saw for cutting metal.
In order to get the full potential out of it, I built a metal stand so I can use it like a traditional vertical bandsaw.
My stand is essentially a metal version of this wooden one made by Honus, coincidentally made to use with the same model of saw (DeWalt DWM120 Portable Band Saw).
If you're looking to make a metal stand for your portable bandsaw, hopefully this will help you out. It's a great project to practice some welding as well as a bit of precision metalwork. Thanks for checking this out.
