Get a discount as Endurance Lasers put metal engraving to the test

Beau Jackson

Endurance Lasers gives makers the ability to upgrade 3D printers, CNC routers and other DIY machines with multi tool functionality. By installing a laser diode, these machines become cutting tools and engravers, capable of writing on acrylic, wood, leather and metal, maximizing workshop productivity.
The lasers can be installed on any 3D printer or CNC machine to extend capabilities.
Read on for an exclusive discount.

The 8.5W+ laser, exclusively available to order from the company’s website, is the second most powerful diode in Endurance Laser’s arsenal. Providing “infinite continuous power,” the 8.5W is capable of writing on all manner of surfaces, from stone and wood to leather and sheet metal.
In a series of Endurance experiments, we see how the 8.5W+ makes short work of matte & hard steel, and glossy & composite aluminum.

Não hajam dúvidas, a Impressão DLP é o melhor que há, em fidelidade ao Modelo 3D.

Este Modelo, até é melhor que os anteriores, porque em vez dum Laser a andar, usa uma Imagem por camada, e são camadas ínfimas, o que, claro, dá numa fineza de acabamento, de fazer chorar as pedras da calçada... E a menos de 500 Dólares!

Mas, menos de 500 Dólares, também significa um volume máximo de 11,5 x 6,5 x 15,5 Cm, e atenção, há uma cura do Objecto a fazer, e limpezas a executar, porque isto de resinas, é mesmo assim.

Anycubic Photon Review: A DLP 3D Printer For Less Than $500
Anatol Locker

Too good to be true? Not at all! Read our Anycubic Photon DLP 3D printer review and follow us on the journey from unboxing and assembly to the first prints.
As far as low-cost desktop DLP 3D printers go, the new Anycubic Photon DLP 3D Printer has emerged as one of the most appealing options on the market. Anycubic has a reputation for building reliable and affordable printers like the Anycubic i3 Mega FDM 3D printer. When it comes to the price, the Anycubic Photon is no exception – it’s one of the cheapest DLP 3D printers out there.

Don’t miss: 20 Best Resin (SLA/DLP) 3D Printers 2018
We recently got our hands on the Anycubic Photon, and decided to give it a test run. Although this isn’t a full-fledged review, we wanted to document our first experience with this unique 3D printer, as well as the unboxing and assembly process. We will continue to update this review as we get more familiar with this beastly little machine.

The Anycubic Photon DLP 3D printer is generating some serious buzz across the community, and for good reason. Priced right around $450, this machine is a potential game-changer for the SLA/DLP desktop 3D printing sector. But talk is cheap; we wanted to see this 3D printer in action.

Learn How to Make Your 3D Prints Truly Transparent

Pinshape Blog

3D printing continues to advance in its ability to create visually accurate prototypes, but most machines are still unable to produce optically clear parts. In this post, you’ll learn why 3D printers struggle to make objects clear straight off the build platform, and you’ll discover 3 techniques for making optically clear parts.

Why Aren’t 3D Prints Clear?
A smooth lake reflects surrounding objects, but when agitated the image warps and distorts. On a smaller scale, this is the effect that causes 3D prints made in a clear material to appear slightly opaque. Layers of a 3D print take on a slightly oval shape creating small gaps between layers that refract light and distort the image.

The above graphic from Taulman3D shows how light travels and bounces inside the layers of a 3D print. The purpose of the techniques you’ll learn today is to either add or subtract material from the print in order to flatten the layers and allow light to pass through without refraction.

The Back Pocket Soldering Kit
Bean_MD

As a budding electronics enthusiasts, I made alot of things on my farm autonomous. With that came the problem that my soldering skill is a bit dodgy.
Recently I had to repair a few of these dodgy solders, which means I had to disassemble and take the part with me to the workshop.
This is a 10km + drive.
So as it is said, necessity is the mother of invention.
This is my kit I can drop in my back pocket, in my cabby hole, I even have one in my sun visor.

CES17: ARDUINO UNVEILS LORA MODULES FOR THE INTERNET OF THINGS
Brian Benchoff 

WiFi and Bluetooth were never meant to be the radios used by a billion Internet of Things hats, umbrellas, irrigation systems, or any other device that makes a worldwide network of things interesting. The best radio for IoT is something lightweight which operates in the sub-Gigahertz range, doesn’t need a lot of bandwidth, and doesn’t suck down the power like WiFi. For the last few years, a new low-power wireless communication standard has been coming on the scene, and now this protocol — LoRa — will soon be available in an Arduino form factor.

Cheap precision drill stand

andrea biffi

When I begun to etch my custom pcb I felt the need to improve circuit drill tecnique. I drilled my first circuits by free-hand with my Dremel, but despite it's very fast, it's subject to errors, and it's also dangerous, because the drill bit is very narrow and weak.

I've searched a column drill as the "Proxxon Bench Drill Press TBM 115" but it's a little too expensive. I've found also a vertical stand for Dremel alt 50€, but it was a model with a single metal column as rail, similar to the most you can see with a "drill stand" search, and it had a low precision in horizontal movement of the bit. In fact you felt the head moving of about a millimeter, which is a lot when your bit is so narrow. So I decided to build it by myself.

E ainda fora do alcance do Público em geral, eis uma Impressora...

Mas bnão se assustem, que é uma Impressora de Filamento, com um Extrusor normal, mas que pode inclinar a placa de deposição, em 2 eixos, e daí 5D, ou mais exactamente, 5 graus de liberdade, no movimento.

O que isto traz de muito útil, é que esta máquiina imprime não só em camadas planas, mas em camadas CURVAS, o que para além dum sem-fim de usos possíveis, e do fim das "escadinhas", significa sobretudo, Objectos com um grau de resistência muito maior...
Por serem feitos seguindo as Linhas de Força exercida sobre esse Objecto, tal como os Edifícios, que seguem a arquitectura da maior força com o menor Material.

 

3D Printing is So Last Week...Say Hello to "5D Printing" at Mitsubishi Electric Research Labs!

Clare Scott  

 

We all know what 3D printing is – obviously. (If you don’t, here’s a handy overview. Welcome, newcomer.) We’ve also explored 4D printing, which involves printed objects that mutate and morph into different shapes when exposed to an outside stimulus such as light, water or temperature changes. So what’s involved in 5D printing? Printed objects that levitate? Printed objects that teleport? Time-traveling printed objects?!

Well…no. You can 3D print a TARDIS, but you still can’t make it travel. 5D printing is simply another name for five-axis additive manufacturing, and while it may not be as exciting as teleportation, it’s still pretty cool – and useful. The term “5D” as applied to five-axis printing is being used by Mitsubishi Electric Research Laboratories (MERL), the North American subsidiary of the multinational corporation’s research and development branch. They’ve been experimenting with a print bed that actually rocks back and forth on two axes, creating a fourth and fifth axis as a result.

What this means for the final printed part is that instead of being created as a series of flat layers, the layers are curved. William Yerazunis, Senior Principal Research Scientist at MERL, describes the advantages of this process as applied to a pressure cap. A cap printed using standard 3D technology will be quickly ripped apart along the adhesion lines when pressure is applied, he explains. But if that same part is printed with the 5D method, curving the lines where the maximum stress will be applied, the part will be three to five times stronger – and will use 25% less material.

Chimera: $60 DLP High-Res 3D Printer

matstermind

I have been on a hunt for the past several years to find a cheap and simple, yet moderately high resolution 3D printer. I had 3 different 3D printers partially constructed when I heard about the amazing technology of DLP Stereo lithography (SLA) printers. I have finally found enough parts at the right price to construct a fully functional printer capable of amazing quality with spending less than $100. Top down DLP printers in their simplest form have only one axis of motion, a video projector, and minimal electronics. They do not require a heated or perfectly level bed, there is never a clogged or wrong temperature in the extruder as it does not use an extruder. And the resin used has a comparable price to FDM printers.

The chimera (ky-meer-a) is a mythological creature that is made up of 3 different animals, this printer is made using the recycled/modified parts of 3 different categories (projector, toys, and old computer stuff), hence the name.

I am always looking for constructive criticism, let me know if you think i can improve on the project, or the instructable!

E se quizerem uma Impressora capaz de imprimir objectos maiores, têem esta, que fica um pouco mais cara, mas faz com que a diferença valha a pena!

E, francamente, é bem mais sólida.

"Little Dipper" SLA/DLP 3D printer for under $500 (projector included)

marshallpeck

A brief overview:

This Instructable is about building a simple yet versatile resin (SLA) 3D printer that uses a cheap DLP projector to build the part from the "top down". This orientation of the light source is similar to other large scale industrial SLA machines. It has some advantages in simplicity, scalability and disadvantages in minimum feature size and print time.

This version build is budget conscious, has a low part count, can easily be upgraded and scaled in size. The entire 3D printer (projector and resin included) can be built for just about $500 or less which makes it one of the cheapest bang-for-your-buck 3D printers using SLA resin out there.

There are many good Instructables and resources that contain more exhausting detail about DLP resin 3D printers and background information. If you are interested in learning more about this http://www.buildyourownsla.com/forum/ will be one of your best community resources for knowledge relating to the topic.

Making Custom Lenses

Robb

The world of optics and lens manufacturing has traditionally been closed off to non-experts. It doesn't have to be that way. Using rapid prototyping tools like 3D printers and CNC routers, making a lens is easier than you might think.

You can use the technique outlined in this Instructable to make very large lenses, lenses that produce special effects, and sculptural lenses with freeform shapes. You'll need to know how to use a CNC router or have access to a nice 3D printer. With one of the two you'll be able to start making lenses right away.

Long Bed Printed 3d Printer

dmserve

The Long Bed 3d Printer was created to see how much of a 3d printer could be printed. That lead me to design a frame that could be printed on a heated bed, soon discovered I needed a larger build surface. After making a way to accurately control a larger bed, I had the maximum size that the frame pieces could be. By combining different parts I was able to get the main frame down to 9 pieces.

Gigabot Proves Even 3D Printing is Bigger in Texas
Tyler Winegarner

After their wildy successful first Kickstarter back in 2013, re:3D’s latest iteration of Gigabot, an extra large 3D printer, is Open Gigabot, which currently has two days left on its Kickstarter campaign. The Open Gigabot files are being released on Wevolver, a social enterprise for open source hardware.
Make: spoke with re:3D Co-Founder Katy Jeremko about the ecological inspiration behind the jumbo-sized printers. She says that re:3D wanted to “allow individuals worldwide to 3D print composting toilets or other human-scale solutions from trash.” The team decided to focus on developing a toilet printer, now known as the Gigabot.
