No último post, falei-vos de reciclagem de plástico, desta vez, vou falar-vos de Filamento 3D feito em pástico re-aproveitado:






WHAT WE DO

Spools of 3D printing filament are currently sourced from scratch, but CLP has developed technology to produce this material from everyday plastic waste instead. Compared to other recycling processes, making filament from plastic waste (think cups or packaging) is small-scale, quick, and low-energy. CLP will make 3D printing more sustainable by bringing high-quality recycled filament to a growing market of consumers.
CLP manufactures ready-to-use 3D printing filament spools in Irvine, CA. The current product line includes PS, and we are actively working towards ABS, PP, PLA, and PETG. CLP sources the waste plastic from local Materials Recovery Facilities as well as direct waste generators such as local resorts and university campuses.












Moldagem em Silicone é do melhor que há, em preço e facilidade, e torna-se uma maravilha, se este Projecto continuar, um Programa que vos habilita a produzir moldes bem complexos, em 2 partes, a partir da vossa Impressora 3D!







Metamolds: Creating ideal 3D printed silicone molds faster and cheaper
Thomas

Silicone molding is an affordable production method that can allow you to make a series of identical objects for prototyping and functional testing. Until now, however, fabricating molds for casting complex objects required a lot of experience and also involved manual work, which made the process slow and expensive. Scientists at the Istituto di Scienza e Tecnologie dell'Informazione (ISTI-CNR) and the Institute of Science and Technology Austria (IST Austria) have developed a new tool for fabricating digital objects through reusable silicone molds. The tool automatically finds the best method to design the molds, and also delivers templates for so-called "metamolds": Rigid, 3D printed molds used to fabricate the optimized silicone molds.

Homemade CNC with 3D Printed Parts - Redesign
Leon van den Beukel

This is the second version of my DIY homemade CNC. It's a complete redesign because of some issues that I've had with the first one. The main issue with the first version was that the wooden Y axis was getting warped (by moisture I guess). Also the bearings were too small and the aluminium X rails were not strong enough to carry the weigth. That's why I've switched over to use 20mm x 20mm square steel tubes for both Y- and X axis. I've designed the 3D printed parts with Fusion 360 and used Inkscape for the Y axis drilling template. To control the machine I'm using an Arduino UNO with GRBL firmware and an Arduino CNC Shield. There are plenty of tutorials to find on how to connect and use it so I did not show it in the video. Here are some useful links:














E para terminar por hoje, um Instructable para tele-controlarem o que quizerem, usando o Arduino, ou o Pic, ou qualquer outro Micro-controlador!







RF Transmitter and Receiver
OEsirik

In this project, I will use RF modules with Pic 16f628a. It will be a short tutorial about rf. After you learn ho rf modules communicate with each other you can use these modules with pic microcontroller, ardunio or any microcontroller. I controlled RGB LEDs but If you can control many thing motors or relays.

Embossed Metal Artwork From a Pop Can
paigenoelle

While pop cans have a deposit in my state, other canned non-carbonated drinks like lemonade do not. The recycling center is a bit out of the way from me, so I wanted to give reusing these cans a try first. There’s a lot of flexibility in materials and methods in this project, so I’ve tried to highlight substitutions as best as possible.
Note: this project involves sharp edges and cutting tools. If you are looking for a project suitable for children, consider using aluminum foil as discussed in “Substitute Materials.”

Impressoras 3D... De Sucata? À medida? E outras máquinas à medida, como orientar as vossas peças 3D, Impressoras maiores, e Impressão sem-fim!

Isto é uma maravilha!
Não só podem construír uma Impressora 3D, a partir de Sucata Electrónica, como, ainda por cima, aquela que vocês puderem arranjar!
 
À medida das vossas possibilidades! 

A partir dum programa que descarregam, Retr3d, e do FreeCad, ambos grátis, é calculada uma Impressora que vai usar o que apanharam, para poderem ter 3D por quase nada...
Impecável. 




Retr3D Building 3D Printers from e-waste
How Does it Work?

NOTE: The Retr3D printer has been redesigned and now is as shown above. Designs for V2.1 can be found here. For build instructions see the file named "Build Documentation Master.pdf" in the Documentation folder. If you need help preparing V2.1 STL files for your printer please send an enquiry to enquiries@techfortrade.org.
Retr3d is a framework dedicated to affordable 3D printing equipment for developing economies that can be locally sourced, locally maintained and locally improved.
We believe that 3D printing can be as transformative in developing countries as the mobile phone. As with the mobile phone, which has already changed the way people across the Africa communicate, introducing 3D printing at the community level offers the potential to localize manufacturing. Which is why we are making it possible to build Retr3d machines from the thousands of tonnes of e-waste which would otherwise end up as landfill.

Retr3d creates 3D printer designs based on the materials that you have access to. Retr3d can create printers form mismatch parts gathered from e-waste. All you need to do input the important the important dimensions of what you are using and Retr3d will handle all of the design changes required to make a functional printer. The designs are created using a series of Python scripts that are run in FreeCAD. When the design is finished, a folder is created with all of the design files and STL files needed to build the printer. With Plater and Slic3r integration, Retr3d can even arrange and slice the STL files for you.
Getting Started
 Read the safety documentation.
 Download and install Retr3d and FreeCAD.
 Download and read the note: "E-Waste Components" from the files tab.
 Download the "Retr3D BOM" from the files tab and gather your materials.
 Follow the "Retr3D instructions" from the files tab to design and build your printer.













E é também à medida, que podem fazer Máquinas-Ferramenta, como esta, que soa mais próxima das Indústrias Portuguesas.
Para que nâo tenham a ideia de que a Vention é só para Impressoras 3D, vejam   aqui   uma Cortadora de Tecido, idealizada na Net, por quem precisou dela, e pronta a ser-lhe mandada, às peças.
Um trunfo para Empresas e Indústrias Nascentes...



Fabric Cutting Machine
Stephen Galle

DESCRIPTION:
Machine to cut fabric at different lengths, max. 3m. A pneumatic gripper on gantries, driven by 2X timing belt actuators, grasps the fabric on one end of the table. It pulls the fabric all the way to the other end, in sync with feeding rollers. When the required length is reached, clamps hold the fabric in place and another timing belt actuator allows for a circular blade to cut.











O que se imagina, e o que acaba por saír da Impressora 3D, raramente coincidem, à primeira, por isso, para evitar dores-de-cabeça, eis este belo Artigo, da Sculpteo, sobre como orientar as vossas peças, de forma a terem os melhores resultados:






How does part orientation affect your 3D printed parts?
Katarzyna Plewa

In all the traditional manufacturing processes, orientation is a parameter which has an impact on the feasibility of the part. A bad orientation choice will make the part complicated to produce, and will raise the cost of the final part. With machining, you try to minimize machining time, and thus, to minimize the number of operations and positions. With casting, you try to find the most simple mold. In all cases, the technology and the orientation of manufacturing are parameters that need to be taken into account as soon as part conception begins.

Some additive manufacturing processes are not impacted by orientation when it comes to the feasibility of the part, that’s mainly the case for powder-based technologies such as SLS or HP Multijet Fusion. With these technologies, part orientation mainly has an impact on the quality of the final part.

Quando quizerem fazer uma Impressora mesmo grande, não se fiquem pelos 12 Volts das pequenas, vão até aos 24 Volts, e uma placa aquecida, a funcionar a 110 V!
E está aqui abaixo, como o fazer.








Upgrading 3D Printer From 12 to 24 Volt
Core3D

My CoreXY is a beast. It has 4 2A stepper motors, 4 TMC2130 stepper drivers, 110 Volt heated bed, enclosed case and for almost 3 years now has been running on a 12 Volt knock off RAMPS 1.4. It's like a corvette running on a corolla engine.
There is anecdotal information about things heating up faster (which I'm not convinced of as you will change the heater cartridge) but most importantly, I've read that TMC2130 Stepper drivers operate better on 24 Volt and stepper motors have more torque when upping the voltage.
If anything, as you can see from the images above, upgrading to 24 volt certainly has made me revisit my wiring. That alone brings a feeling of immense satisfaction.
In this instructable I will discuss the 24 volt upgrade of my printer which is a CoreXY with 2 2A steppers, 2 1.7A steppers, Direct extrusion, parts cooling fan, controller cooling fan and LEDs.
In my upgrade I'm using a KFB2.0 controller board but there are many other alternative boards that can handle 24 Volt. The RAMPS 1.4 happens to be one that is not built to handle 24 Volt (there are upgrade options to that).
Many of the items will be similar in your printer and might be handled the same.

New conveyor belt 3D printers Polar3D Flash and Printrbot Printrbelt
Michael Petch

3D printing with conveyor belts has seen a flurry of activity this year. Now, Bill Steele of Polar3D has posted several interesting videos featuring new 3D printers.
The Polar3D Flash FDM printer uses a conveyor tilted at an angle to produce a continuous stream of parts. In the video the print head moves in the X and Y axis, as in any cartesian FDM machine, however the Z axis is a conveyor belt – angled at 45°.
Another video posted this week shows a 3D printer Steele calls the Printrbot Printrbelt. This machine is the result of a partnership between Polar 3D and Printrbot.
Brook Drumm from Printrbot demonstrated the Printrbelt ahead of sending it down to the machines first public demonstration at the International Society for Technology in Education (ISTE) event in Texas earlier this week.
The Printrbelt’s printhead moves on an X axis angled at 35° to the Z axis composed of a heated print bed conveyor belt.  Drumm got in touch to tell use, “It’s out of beta and for sale for early adopters who want to get on that bleeding edge.”
The Printrbelt also features automatic part ejection.

E-Waste Quadcopter Lifts Your Spirits While Keeping Costs Down
Rich Bremer

The advancement of Quadcopters and their capabilities over the last few years has been amazing. Unfortunately, the price point to get into the sport with a decent size, non-toy, vehicle is still several hundred dollars. And what’s the fun with buying one when you can built it?!? Strapped for cash and feeling the same way, [Hans] over at the hackerspace Knackatory decided to build a quadcopter from e-waste.
The + shaped frame is made from lightweight plywood. It’s pretty obvious that the main rotors are PC Fans, 140mm in this case. Normally, these wouldn’t be able to create enough lift to get out of their own way except the on-board 24v Dewalt cordless tool battery bumps up the fan speed to 15,000 rpm. The one orange fan allows the operator to maintain a visual reference to which side of the ‘copter is forward.

Para quem tem problemas com a Impressão 3D, usando Policarbonato, cá vem metacolin, da Prusa, ajudar-vos com uma mão-cheia de Dicas, e a melhor, penso eu, é a de assim, substituír as peças feitas em ABS, em tudo o que seja máquinas...





Polycarbonate: Here's how to print it without warping, delamination, or an enclosure, with better-than-ABS results.
metacollin

You're probably a bit skeptical, the title sounds to good too be true. But benchy don't lie:

All of the parts in the attached photos were printed using the crappiest/cheapest polycarbonate filament I could find on a stock Prusa i3 Mk2s, the glue stick it came with, and some fairly unusual Slic3r settings.
If you aren't familiar with polycarbonate, it's what bullet proof glass is made out of. And it is notoriously difficult to print. To the point that the 'action shots' of eSun etc. shows, well, pretty crappy results in the 3D printed objects.
But I think that's because we're taking a fundamentally incorrect approach to printing PC. I'm getting excellent results. I see no reason to print ABS, PETG, or even nylon at this point - all polycarbonate, all the time. Er, I'm obviously more about practical prints that need strength, PC is not going to be a good replacement for PLA for aesthetic prints :).
I'm currently in the process of replacing all ABS parts on my printer with polycarbonate ones, now that I have a good printing process figured out. Let me tell you - aside from being comically strong (PC's nickname 'King of the Filaments' is well-earned), the dimensional accuracy is just killer. I remember having trouble getting a few nuts in their holes when assembling my Mk2s from a kit, the ABS tolerances just weren't that great. Nothing some percussive maintenance couldn't fix, but still.

Glowforge Launches the 3D Laser Printer That Made Crowdfunding History
Glowforge

For the first time ever, laser cutting and engraving technology has been freed from the factory and made easy and affordable for home and small business use.
“From the very start, we designed the Glowforge 3D laser printer to unlock people’s creativity,” said Dan Shapiro, CEO of Glowforge. “We set out to re-invent the idea of ‘homemade.’ What if you could print what you wanted, when you needed it? What if you could sketch a design, then turn it into something real you could use, without complicated software? What if your gifts were personal instead of purchased? What if it was easy to print your ideas a hundred times, so you could launch a business?”
Glowforge sets up in just minutes and works via Wi-Fi. No software is required, as it uses the web browser or app on any Mac, PC, tablet, and smartphone. Users can create and print from software including Adobe Illustrator, Inkscape, CorelDraw, Adobe Photoshop, GIMP, Autodesk 360, and Sketchup. They can also bypass software altogether – the onboard cameras can scan a drawing and transform it directly into a beautiful print on almost any material.

Digital Alloys raises $12.9M Series B from G20 Ventures, Boeing for metal 3D printing
Thomas

Boeing HorizonX says it’s investing in Digital Alloys, a Burlington, Mass.-based company developing high-speed, multi-metal additive manufacturing systems that produce 3D printed parts for aerospace and other production applications.
The $12.9 million Series B financing round was led by G20 Ventures, while Boeing HorizonX Ventures, Lincoln Electric, and Khosla Ventures also participated. Khosla Ventures is a prior investor which led Digital Alloys’ $5 million Series A round of funding in 2017.
Digital Alloys was founded in 2017 when it was spun out of New Valence Robotics. Digital Alloys developed a patented Joule Printing™ metal additive manufacturing technology, a radically simple new process that uses wire feedstock and high deposition rates to print hard metal parts faster. This new 3D-printing approach can rapidly combine multiple metals into each part, which enhances thermal, electrical, magnetic and mechanical properties. Digital Alloys says its technology avoids the cost and complexity of powder-based systems, and delivers higher resolution than other wire-based 3D-printing techniques.

Tinijet — Affordable Waterjet Cutting At Home
James Hobson

While laser cutting remains the dominant force for rapid prototyping anything made of plastic, MDF or wood, the real holy grail is the ability to cut metal — something most laser cutters are just not capable of.
In the industry, this is done using extremely high-powered laser cutters, plasma cutters, or water jet cutters. All of which are very pricey equipment for a hacker. Until now anyway. Introducing the Tinijet, the missing tool for affordable water jet cutting.
We first covered this project a few years ago when it was just a university research project called Hydro — it’s since evolved immensely, and will be available for sale very soon.

Step-by-step Guidance to Build a Drone From Scratch Using Ardupilot APM Navio2 Flight Controller
Simkaisheng

Ardupilot is a widely used open source unmanned vehicle autopilot software that is capable of performing many functions. Documentations and various sources have provided us with the basic knowledge of the setups and use each separate component of a drone but none has provided a detailed guide on how to put them together to build the drone’s hardware with guided steps of component setup and assembly from scratch, together with all necessary configuration and setups.
This article is written to combine all scattered information into one piece, to provide a step-by-step guidance from head to tail of how to build and assemble a quadcopter from scratch and how to perform all setup configurations required using the Navio2 Ardupilot flight controller. Other flight controllers from APM or others can also partly rely on this guide.

How To Print Resin-Like FDM Minis on $200+ 3D Printers (Printing The Game #3)
3D Printed Tabletop

In this video I show you how to get even your $200, stock FDM printer printing nearly layerless, detailed, miniatures in no time. No, these aren't meant to be a replacement to resin prints - but this is a great alternative until you can afford an SLA/DLP resin printer. I used a Creality Ender 3 to print the minis in this video, but the profile down below works with other printers in the Creality family as well (like the Ender 2 and CR10/CR10S). I also share the secrets of this profile for those who don't have a Creality printer so you can make your own profiles and/or adjustments to start getting better quality minis on your FDM printers in no time.

Waterbot: Arduino Robot Boat
Slant Concepts

The Waterbot is a robotics arduino boat. He can be programmed from scratch using arduino tools or just built and contolled using the LittleBots app. It is currently Live on Kickstarter.
At Slant, for the past two years, we have been developing and manufacturing 3D printed arduino robotics kits. Up to this point we have created 5
When we started on the 6th bot, we knew that we wanted to go where no robot had gone before. So we chose water. No one in the entire Arduino community had created a robotics kit for the pool or the puddle. We fixed that.
Now STEM students and hobbyists have a programmable arduino platform for exploring small ponds or just being creative in the water. You can use this kit to learn basic robotics, flotation, hydrodynamics, electronics, and programming.
