Façam a vossa Impressora 3D! E imprimir em 5 eixos(!), afiar Serras, Caixas em chapa, e uma Bomba de Àgua!

 


Podem, façam!
Esta maravilha ode ser vossa, se se deram ao trabalho, e assim ficam com uma máquina bem respeitável, em Volume de Impressão, e Qualidade, e carregada de extras.
Bem melhor que comprar uma Impressora da tanga, por montar... 






3D Printer Cantilever 2.0 C3Dt/c
Core3D

This is my latest completed project to date. I'll be happy to build one for you (see update below), but if you must go it yourself; here is the instructions for the C3Dt/c (c for cantilever) by Core3D.tech. This printer was presented at MRRF2018
It is the culmination of many of my other intructables and I will refer/link to those as needed.
The 3D printer is a Cantilever printer with the following features:
  •  200mmx200mmx260mm Build volume
  •  Heated bed
  •  Auto Bed Leveling using inductive sensor and Aluminum bed
  •  Linear Rails (MGN12 250mm) on both X and Y axis
  •  Dedicated Parts cooling
  •  Runing KFB2.0/Marlin 1.1.8
  •  Bowden Extrusion with MK8 Extruder
  •  8080 Inc 1010/1020 frame
  •  Auto tensioning on X and Y Axis
  •  Double Rod Lead Screw Z axis using 12mm rods for extra stability.
  •  V6 All metal hotend with cooling adapter for Noctua cooling fan (ultra quiet)
  •  SD card reader as well as accessible USB port for direct computer access or OctoPrint











Imprimir em 5 eixos, é, numa só frase, imprimir às curvas!
Pode parecer caricato, mas não é de beber, é antes, uma maneira de imprimir formas impossíveis com as actuais,  e imprimir objectos muito mais fortes!
Porque a base onde de imprime roda, as camadas podem ser curvas, o que permite uma estrutura muito mais resistente...
Bem pensado!


In a nutshell, this  makes the Printer lay Filament in CURVES. 
Witch allows both for print jobs not possible on today's 3D printers, and for a very strong print, as it can follow a curved deposition path.
Good Idea!









5D Printing: A New Branch Of Additive Manufacturing
Jessica Van Zeijderveld

3D printing has already been around for quite a few years. Then, a bit more than a year ago, talks of 4D printing started to circulate – which we have wrote an in-depth blog post on as well that you can read here. But now, the idea of 5D printing is being talked about and experimented with. 5D printing is not an evolved version of 3D or 4D printing as it is with audiovisual aspects of different dimensions – it is less complicated than that. You can see 4D and 5D printing as roots originating from 3D printing. In this blog post, we will first explain to you what 5D printing is, then we will tell you what the benefits are and how it can be applied. Last but not least, we will tell you what the differences are between 3D, 4D and 5D printing along with how you can keep up with the latest technological advances related to additive manufacturing.

Eis como podem afiar as vossas serras de Mão, mas suspeito que este conceito ainda servirá para sabe~se lã que outros fins...



A Gizmo Maker's life will occasionally lead him into... Woodworking!
So here's how to keep those Hand-saws fit:




Filer Guide for Hand-Saws
Mikhandmaker.

Sharpening a saw can be one of the most "difficult" tasks for a woodworker. I built this guide for sharpening hand-saw teeth at the required relief angles, for both rip saw and crosscut saw.
Inspired in an old tool from 1987 hard to achieve (at least where I live) and using materials available to anyone, I show you the step by step to make it by yourself.
  •  It is very important to clarify that the files work only forward. Therefore, the force when sharpening only has to be in that direction and the backwards without pressing, thus, we will avoid premature wear of the file.

Hydraulic Ram Pump
habolooby

Pump water with no electricity, no gasoline, just gravity!

Sound crazy or impossible? Don't worry, it does obey the laws of physics, but I'll try to explain the operation later. This instructable shows how to build a fairly simple water pump that needs no energy input other than water flowing from a higher point to a lower point. Most of the pump is constructed from PVC, with a couple of bronze pieces thrown in for flavor. I was able to source all of the parts from a local hardware store (Lowes) for a bit under $100.

To function, the pump does require a reasonable amount of water that will drop at least 3'-5'. The level that the pump can raise water to depends on the water's head (total drop the water will make).

Um PC por menos de 150 Dólares, é o que podem fazer com um Raspberry Pi, seguindo este Instructable.
Assim, evitam comprar um PC Desktop, para usos que não o justificam, como controlar gigajogas, ou jogar Jogos...





Pocket Pi - a Raspberry Pi Computer for Under $150
TheInventionMaker

This is a affordable $100 raspberry pi computer. This computer is not the thinnest or prettiest thing on instrutables. This is for getting the job done. The shell is 3D printed. There is 1 charging port, for the motherboard. The keyboard has a wire designated for charging the keyboard and will not be noticeable on the outside. There are 3 USB 2.0 ports are for input. 1 will be used by your bluetooth + wireless USB stick. Luckily, I have included a USB holder that holds your USB's.
The screen is 4.3 inches and is not a touchscreen. You can easily make it touch screen compatible. The raspberry pi is a zero. This is because the Adafruit Kippah currently does not support the zero w. You will still need a wifi network! It runs NOOBS, but you can still download PC games on it. All you have to do is to search on google how to install PC games on NOOBS.
You can use this to check up on things, play games, and use applications that are normally on PCs. It can do a lot of things that phones can do, but the computer is significantly cheaper. The parts are spread across 3 different websites. If you do not have a 3D printer or a soldering iron, you will have to but different parts. This will be explained in the steps. It should take you around 1 hour to build, but with shipping times and how long your 3D printer takes to print the parts, it could be longer.

A Pocket $200 Night Scope, now, that sounds real Neat!









3D Printed Night Vision Scope
Happy_Mad_Scientist

Hey everybody!!! Hows it going?!?!?! Ok, so for a long time (~3 yrs.) I have been building these digital night vision cameras, and after over $1,000 and hundreds of hours in R'n'D later, I give you the "Eagle Scope 1.0" (named after the camera inside)!!!
It's a pocket-sized, 3d printable night vision monocular that you can build yourself for ~$200!!! Oh, and it is top of the line, sporting a near-eye display (that doesn't burn out your eyeball), a .00001 lux camera with an OSD, a rechargeable 3hr battery, and an (optional) external DVR for recording the footage!!! Best of all, it fits in your pocket!!! Over-enthusiastic!!!!!! But seriously, this thing kicks some major buttocks.















Um Motor feito com Ímanes Permanentes, que é um Anel, com a Hélice no meio!
Vejam o Vídeo, para perceberem as vantagens dum tal Sistema, que vale a pena...





Rolls-Royce | Permanent Magnet Technology

The AZ-PM thruster is the latest in a range of Rolls-Royce propulsion products using its permanent magnet technology. This technology is based on electric drive where the motor is in the form of a ring round the propeller. The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets. The rotor, fitted within a series of magnets, turns within an outer ring which form the stator. When current is supplied to the motor from the variable frequency power supply the electromagnets are excited in a particular sequence and the resulting magnetic fields interact with the field from the rotor magnets creating a torque that turns the rotor and its propeller blades.

Plástico acessível? E peças de encaixar, reciclar Esferovite, as melhores impressoras, e XnView











A note: I'll add some words in English, only IF the title is not self-explanatory, and I think of anything else I found that can be said about these Posts.




 

Esta história dos rolos de Filamento, é muito limitadora das possibilidades reais da Impressão 3D...
Cortesia da série de vídeos deste nosso amigo, sob o pseudónimo de Ray Makes. 

Isto é muito promissor. Não só porque há Plástico muito mais barato em grão, mas também porque, com uma misturadora como esta, podem-se até obter misturas de plásticos e outros materiais!
Usa filamento, granulados, e até, fitas, de se cortar garrafas de plástico!
Bravo.



A great way to save money, and re-use your spent filament. 
But...
Will this also allow for different Ingredient Material mixes?
Looks that way!



Pellet Extruder for 3D PRINTER HOTEND
Ray Makes

For 3D printing, the holy grail has been to print directly with AFFORDABLE pellets instead of the expensive rolls of filament. I found this pellet extruder On YOUTUBE of all places. Mahor Muñiz Cadenas (link to his channel below) had spent much time effort and investment developing his pellet extruder and my curiosity got the better of me (but in the good way). From what i have seen of this pellet extruder, it holds alot of promise, so my hopes are very high. build quality Appears great, but the kit had missing hardware and a few design issues that Mahor is still Working out. i purchased the pellet extruder (this is more than just a hotend) a few months ago but wasn't in a hurry to assemble it since i already knew i didn't have a test machine to try it on. now that i have the Folger Tech FT5, i will be experimenting with it VERY SOON. the plan is to learn form this and then use that information to build a MUCH larger scale 3d printer... one that would be too expensive to purchase, but affordable to build.

Imprimir em 3D não é tudo fácil de se concretizar...
Há alturas em que 2 ou 3 peças encaixadas, facilitam muito a coisa, e para isso, os encaixes têem de ser os melhores possíveis.
Para isso, sigam estes conselhos da Sculpteo:



How to connect two parts with 3D printed joints and snap fits
Amandine Richardot

How can you efficiently connect two 3D printed parts? You could glue some components to connect them, but there are other ways to do it, more convenient. Indeed, you can integrate some specific design features directly in your 3D models. These interlocking features will help you drastically reduce assembly time, and designing snap-fits or other kinds of 3D printed joints is not so hard! To learn how to create the best 3D printed joints and snap fits for your parts, follow the tips of our 3D designers from Sculpteo Studio, our 3D design studio specialized in additive manufacturing!

What are 3D printed joints and snap fits?
3D printed joints are all the design features you can insert in your 3D model to connect parts together without using external components (not even glue).

One of the most common kinds of joints for 3D printing is snap fits. These special connections work as follows: a design feature similar to a hook is inserted in another part, where there’s a special hole or space made for it. This is made possible thanks to the fact that this hook is quite flexible and moves while being inserted, and then gets back to its normal position when in the right spot, which blocks it.















Sejamos sinceros;
Para uma peça que é apenas uma placa, ou um bloco de material, não é necessário uma Impressão 3D!
Para esses casos, porque não, utilizar Esferovite, ou Isopor, reciclados com Limonene? 
E ainda...
Pode-se assim usar as Impressões, como Moldes, e sem Injecção de Plástico, apenas moldando essa pasta criada, como se fosse Plasticina!


Limonene is nice...
Both to turn that bulky Styrofoam Junk into a lots less bulky goo, but also, because that goo can serve as Molding material, and 3D prints used as Molds.
Saves time and headaches.








Recycling Styrofoam (EPS) Into Useable Castable Styrene Plastic at Home
killbox

Scope of the project and feature creep:
Recycle small old Expanded Polystyrene foam insulation coolers I get monthly with a medication. Our city has no program that accepts EPS, and so I looked into some experiments with it, and in the process come up with a 'Easy' technique to Recycle EPS (Expanded Polystyrene Foam) not only reducing its size, but also making it into something usable/useful (im calling it “Maker Goop” for now). In a relatively safe and health conscious way.
‘Maker Goop’ Can be handy for making small plastic parts, castings, or just to make the EPS a flowable product for makers, or for Recyclers which could have the solvents extracted and reused commercially, or burned (as is done in the EU for power. It does emit co2 and water vapor and not much else.)
Below are some notes on my experiments on found on Degasifying the EPS (EPS is 90-99% empty space, and 1%-10% Polystyrene. First steps were to isolate a way to turn it from foam into a liquid to both save space, and make it useable. This is also the first step in commercial recycling too. But at this point i'm experimenting on the small scale for home/hobby reuse.
