[Project] 3D Printing Sticks for PLA Hot Glue GunTyler Koslow
Who needs a 3D printer when you have a hot glue gun? This Hackaday project from Donald Papp shows us how to use molten PLA filament to glue 3D printed objects together.
When 3D printing ambitiously sized projects, hot glue guns come in handy as a tool to join two separate things together. But what if you could bind these objects with the very same PLA filament that you used to 3D print in the first place?

Cimento neles!
Já viram que bacansa de Impressoras 3D se faziam, com partes em CIMENTO, para tornar a máquina muito mais sólida?
Até TORNOS se podem fazer com Moldes, seguindo este método.


Useful both for 3D printers a lot more solid, AND even for Lathes, using this Cement Mold idea!



Create Concrete Products With 3D Printed MoldsFurther Fabrication  
In this Instructable I wanted to show you my process, for making 3d printed moulds, to create cost effective prototype products, with cast concrete.

Note, although Metal on the Microwave is a big NO-NO, removing the Kiln, at a certain temperature, and quckly pouring it onto a Mold...
That's feasable.



Derreter VIDRO no Micro-ondas!
E sabe-se lá que outros Materiais não-metálicos.
Porque Metal, no Micro-ondas...
NÃO!

Mas... Isso não impede de se poder retirar o Cadinho, com uma boa temperatura...
E, rápidamente, inserir um pouco de Metal, e logo, se verter para um Molde! 
MEWAHAHAHAHA!





DIY Microwave Kiln | Fuse Glass in Your MicrowaveShakeTheFuture 
In this Instructable, we'll look into way to make a microwave kiln.
For those who don't know what is a microwave kiln, here is a quick introduction.
Microwave kiln is a kiln that you can put in your regular microwave oven.
It does not use a wire heating element or gas to heat up. Microwave kiln is covered with silicon carbide.
Silicon carbide absorbs microwaves and turns them into heat.
Microwave kilns are usually used to fuse glass.
You can turn broken glass into amazing jewelry.

Annealing PLA Prints for Strength – 2 Easy WaysMiroslav Sarcevic 
Background Information
Annealing, when referring to metals, is when you heat up a material to make it less brittle and more pliant. In order for this physical change to occur, you have to heat the material to a sweet spot that’s cooler than its melting point but hotter than the temperature it recrystallizes at. You have to maintain this temperature for a while and then let it naturally cool down.
...
Annealing Plastic
Though this definition refers mostly to metals, a similar process can also be used with plastic. The technology behind plastic annealing is not new. It has been used for decades in the production of injection-molded plastic objects. Annealing is used to reduce internal stress in molded parts and make those parts stronger and less prone to warping.

IS PLASMA THE MISSING LINK IN ASSEMBLING 3D PRINTED PARTS?
UMAIR IFTIKHAR

Creabis, a Kirchheim-based 3D printing service bureau, is using Relyon Plasma’s piezobrush PZ2, a handheld cold plasma device, to bond 3D printed parts.
The piezobrush PZ2 uses plasma to activate surface particles of a substance which strengthens the adhesion between joined parts. With a strong bond between assembled 3D printed parts, it is possible to manufacture large-sized sturdy components on small sized 3D printers. 
According to the CEO of Creabis, Ralf Deuke, plasma-aided bonding will lead to more novel applications in 3D printing.












Peguem numa Raspberry PI, e numas coisitas mais, e fazem o vosso próprio Computador Portátil todo manerinho, que cabe num bolso, dobrado! 
É bom!






Make a Portable Computer Using a Raspberry PiTylerJohnson

Have you ever wanted a portable computer you can take with you? This is the easiest way to build your own. For those of you who do not know what a Raspberry Pi is, it is a complete computer about the size of deck of cards that can run many different kinds of Linux. This portable computer will be complete with a screen, keyboard, wifi, and a battery. This is just to show how to make the components work on battery, this indestructible does not have instructions for building a case. There are a lot of interesting ideas for cases and I did want to limit anyone's options. I tried to find the easiest way of making a portable all in one battery powered computer.
For this project you will need to be comfortable doing electrical soldering and desoldering; if you are have not done electrical soldering before, there are many tutorials online.

Aerogel feito em casa! E um 4º Eixo CNC, um Modelo de Motor Radial, uma Bio-Impressora(!), gravem a Laser com a vossa Impressora 3D, e o vosso Filamento feito em casa!

Ficam a saber que há uma Org que vos ensina a fazerem...
AEROGEL!
Impecável!
Tudo, desde a aparelhagem, até aos diversos tipos desse sólido incrível que é o Aerogel, o que não é nem rápido nem barato, mas para Universidades, e diversos Grupos de Nardos, deve dar...









How-To: Make Your Own AerogelSean Michael Ragan 
The folks at Aerogel.org are serious about it: The “Make” section of their exhaustive “open source aerogel” site will teach you how to make high-quality monolithic aerogel the way the pros do it, from building your our own supercritical drying apparatus (“manuclave” is their neologism), to mixing up the wet ingredients, to actually performing the supercritical drying operation. It still won’t be easy or cheap, but all the information you need is right there, well organized and clearly explained. 
https://makezine.com/2012/02/01/how-to-build-a-supercritical-dryer-and-make-your-own-aerogel/














A vossa Fresa CNC pode melhorar muito, com este 4º Eixo, que a transforma quase num Torno CNC de origem...
É bom!









CNC Router Rotary Axis
mkmra2
My router was a 3-axis machine. Adding a 4th rotary axis allows considerably more flexibility as the part to be machined can be rotated to expose different faces for cutting. I'd previously done some 4-axis router work at Stamps School of Art & Design - here's that post. I really wanted to add this capability to my router.
After exploring a few options - most of which were very expensive - I chose to go with an inexpensive kit from China. It was only $358 including shipping. I'd have to figure out how to get it hooked in to the electronics then build my own mount.














Eis algo de nada banal, para fazerem com as vossas Impressoras 3D...
Um Modelo de Motor Radial de 7 Cilindros!
E sem complicações de montagem, por isso, de que estão à espera?







[Project] 7-axis Hand-Cranked Radial Engine ModelMika Yeap 

Hand-cranked and fully functional, this is a model of a seven-cylinder radial engine by plusalphaDesigns. It’s a “reciprocating type internal combustion engine configuration in which the cylinders ‘radiate’ outward from a central crankcase like the spokes of a wheel,” according to Wikipedia.
It’s a relatively painless model to assemble and print, requiring just a handful of plastic parts – you don’t even need any fasteners. So let’s jump right in!

https://all3dp.com/1/project-7-axis-hand-cranked-radial-engine-model/











Isto existe MESMO, uma Bio-Impressora para Laboratórios, e podem fazer uma destas por uma fracção do preço das do Mercado!





Low Cost Bioprinter
mechbioprinter

The goal of this project is to develop a low-cost bioprinter to make bioprinting more accessible to research institutions. Currently, low-end bioprinters cost approximately $10,000 while high-end bioprinters cost approximately $170,000. In contrast, our printer can be built for approximately $375.













Só coisas boas!
Não é que podem transformar a vossa Impressora 3D numa Gravadora Laser?
E não é muito difícl, nem caro!





Convert a 3D PRINTER to LASER ENGRAVER | Under 40$Jakes

- To start this project we are gonna need a laser that is strong enough to burn into most of the household materials. I found that 500 mw laser is just right for this project due to its low price and capability of engraving in almost every material with exception of metals and glass.
-I bought my laser on Aliexpress for a small price. Here is the link: https://goo.gl/obFmFD
-With laser you will also get a laser driver circuit and a safety glasses which are necessarry when operating with lasers.

Build Your Own 3d Printer Filament Factory (Filament Extruder)ianmcmill

UPDATE: Now with wiring diagram !
Long read:
3D printers are cool and they finally start to drop in price. Kickstarter campaigns like the one from QB-UP or M3D are popping up and they are finally "affordable". And with affordable I mean affordable like 200 $ and not "affordable" like 2.199$ affordable. However, once you are a proud owner of a 3D printer you will soon realize that your wallet is far from being let alone. No ! You need plastic filament of course to print those super awesome coat hooks and wheel chocks. Since the price for these filaments tend to top the actual material costs, printing before mentioned life savers is kind of expensive and could become a problem to the development of the ever growing 3D printer community
BUT FEAR NO MORE !! Some clever gents came along - Hugh Lyman with his Lyman Extruder may be mentioned here or the guys over at Filastruder.com - and saved the day ! YAY. And there was much rejoicing ! They have built plastic extruders everyone can build or buy at a decent price. However if you are a fellow Instructable.com user the first thing that should come to your mind is "I can build this by myself...and cheaper...". Building at lower costs is the nature of DIY after all.

2019 FreeCAD Tutorial for 3D Printing – 5 Easy Lessons
Rocío Jaimes Gutierrez 

Welcome to our FreeCAD tutorial for 3D printing. FreeCAD is a 3D parametric modeler, designed to create and customize real-life objects. Its beauty lies on the easiness to modify your designs, together with the open-source principle, and of course, being for free.
In this 5-lesson FreeCAD tutorial, you will learn the basic commands and tools to visualize your ideas on screen for 3D printing. We will construct a seemingly simple object – step by step. After each instruction, you will find pictures highlighting the steps. By the end of this tutorial, you will be ready to print your first self-constructed CAD model.














Ora aqui está um Kickstarter a apoiar, um braço-robot OPEN-SOURCE!
Dito de outra maneira, CNC para o Povo!







Evezor: Open Source SCARA Robot ArmJeremy S. Cook

Per this project’s Kickstarter video seen below, when 3D printing first jumped came into the mainstream, many people thought they could now make anything they wanted, perhaps even many of them to sell with no human interaction. While true in some sense, these machines do require human intervention between prints, and can take a very long time to produce useful parts. Additionally, some designs may require a different tool, such as a laser cutter or CNC router. That, of course, means more space and money, and still there is the issue of machine tending.

SCAD to STL – How to Convert SCAD Files to STLBenjamin Goldschmidt 

SCAD and STL files are two common file types for 3D design applications. SCAD stands for “Solid Computer Aided Design”, and the file format is used to describe 3D objects. It was pioneered by a software called “OpenSCAD,” which is a free CAD software for designing 3D objects. STL stands for “stereolithography” and is a popular file type to use with slicers for 3D printing.
The main difference between these two file types is in the way the models are described in code. In STL files, the 3D model is created using a “tiled” set of triangles along the surface of the object. This creates a fully 3D object. In contrast, SCAD files design an object using mathematical relationships. For example, a cube-like object can be described using its length, width, and height. This type of design can be useful for printing objects such as fractal art on objects.
Because the geometry used by STL files is more capable of conforming to complex designs, you may find you want to convert SCAD to STL. Lucky for you, there are two really easy ways to do this.

3 em 1 diferente! E magnetizar e desmagnetizar, soldar PLA, Carvão dum Rocket Stove, desenhar e passar à fresa, e Mosaicos automáticos!

Aqui está uma máquina bem intrigante, com um mecanismo diferente, que eles dizem ser mais rápido e seguro, e parece mesmo ser assim...

E ainda vem com 3 meios de ser usada;

  • Como Impressora 3D
  • Como gravadora de Alumínio
  • Como fresa de plástico
É bom!







3D printer SkyOne 
3dlaboratorio 
Industrial 3D printer SkyOne is meant for printing by up-to-date plastics with melting temperature up to 260 °С. Fused deposition modeling technology (layer-by-layer formation of an object from as fused plastic) is behind a concept of its operation. The printer is realized according a coupled design SCARA (Selective Compliance Assembly Robot Arm), two motors control levers, which move an extruder in XY plane. Feeding along the Z axis is realized by a ballscrew transmission. Scheme SCARA provides an advantage in printing speed over printers, which use Cartesian ordinates. But at the same time the software for 3D printer SkyOne is much more complicated than for printers constructed according a standard design.

Às vezes, é mesmo útil ter uma ferramenta ou um parafuso magnetizados...
Outras vezes, é bem chato, só atrapalha!

Pois aqui aprendem como tanto magnetizar, como a fazer o contrário, desmagnetizar, e é um instructable bem porreiro:







Tool Demagnetizer and Magnetizer
tonyfoale 
Tools sometimes get magnetised, this can be both useful and undesirable depending on the type of tool and the actual job that you want to use it for. For example there are times when having a magnetised screw driver is helpful to hold a screw when you need to put it in an awkward place but unless you want to do that it can be a disadvantage because it will attract any ferrous swarf, nails and screws nearby. Drill bits are a tools which you would not want to ever be magnetised, it will get covered in chips when drilling ferrous material.
That said, we can see that a means to magnetise and demagnetise tools and other objects like vernier calipers would be a useful workshop addition. To magnetise a tool we only need subject it to a strong uni-directional magnetic field and to demagnetise we subject the object to an alternating magnetic field.

Algo, portanto, que vos vai poupar a muita re-impressão maçuda...
E parmite ainda uma Engenhoca em várias partes! 









PLA Welding – How to Fuse PLA Seams and Cracks

Tian Ooi  
PLA welding is a way to fill in gaps or “glue” 3D prints together.
Using a power drill with a small piece of PLA filament instead of a drill bit, the rotating filament is pushed against the 3D printed plastic. This generates friction, which heats up the filament and softens it. The filament is then free to fill in a crack or weld plastic together. After cooling, this creates a strong bond, as if it had been part of the piece all along. 
Inspired by friction welding, a welding technique typically used to fuse metals, PLA welding applies the concept of utilizing rotational friction to plastics instead. Friction welding is often used in industry to join dissimilar materials at more stable temperatures than other welding methods. Applications include the aerospace and automotive sector, joining together turbine shafts, car frames, and more. 











Algo de bem ùtil, fabricarem o vosso próprio Carvão, a partir do super-económico Rocket Stove, que aproveita TUDO duma Combustão, o Comcustível, os Gases, as partículas, tudo!








Charcoal RetortKuzmanic
I have had a couple of attempts making charcoal using 44 gallon drums and they have worked okay, but needing a new project after buying a mig welder, I decided to make a retort.
The theory of a retort is that you heat the wood to be made into charcoal up to a point where it starts expelling all of the wood gas and impurities, which is then fed back into the fire to keep the process going.
After reading up and watching a number of videos on rocket stoves and retorts, I decided to make one with the idea of combining the two into one rocket stove powered charcoal retort.

[STUFF] Polygonia Design Suite
All3DP  
Offering possibly the simplest way to sketch repeating geometric patterns, this browser-based web app is a surefire resource for intricate 2D designs.
We’re not ones for lattice room dividers, but after spending some time toying around with Polygonia Design Suite, it’s just a matter of time before the All3DP office is a maze of fancy laser cut obstacles. A browser-based vector drawing tool for quickly creating geometric patterns, Polygonia is the result of a visit to the Smithsonian and a smattering of high school math and software engineering by its creator, David Kaufman.
Through the simple UI of an online design app, you can sketch out simple line inputs which get instantly translated into rad looking tiled designs. Multiple parameters allow you to customize the design to suit your project and a variety of output formats including SVG and PNG give flexibility for further design software you use after.
