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.

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.

$99 palm-sized PocketMaker 3D printer launches on Indiegogo 

While 3D printers do honestly come in all shapes and sizes, the vast majority of models feature roughly the same desktop size – with size differences usually being negligible. While the dream is always to go bigger and wider to facilitate larger prints and more ambitious projects, there’s a lot to be said for downsizing as well. Aside from the obvious benefit of making your 3D printer extremely portable, it also means 3D printing smaller, more efficient objects and optimally using your build volume. Why be tempted to go bigger if smaller means becoming more efficient? If this sounds appealing, then the palm-sized PocketMaker might be something for you.

3D Printed 1:10 OpenRC Formula 1 car

Daniel Norée  

This is the OpenR/C Formula 1 car. It´s the third generation 3D printed OpenR/C car and this time around focus is on simplicity! You can print everything in PLA except the tires which are done in NinjaFlex! Of course you can print it in any material you like but for those that want to print a car but only have PLA at hand, this is the project for you!

This guide explains how to assemble the OpenRC F1 car. If you want to add electronics to make it radiocontrolled another step will be added later.

Raspberry Pi Surveillance Rover (Land Drone)

DavidDrones  

Ever wanted to have a surveillance drone to monitor your surroundings? Of course you have!

Using a Raspberry Pi for the on-board logic, this compact, mobile computer, will create a local port that streams a video in real-time while simultaneously creating Bluetooth sockets to read values sent by a custom android app. The app syncs with the drone and uses user input to send instructions to the drone instantly. This project is fairly difficult to make from scratch, so hopefully the following will make life easier and provide some insight for drone enthusiasts like myself. All the software used for this project is provided. The code used was originally written by myself, but a few lines might have come from other sources. Feel free to modify and share the code to your liking. Please use the information provided responsibly and have fun!

Power in the Apocalypse (How to build a Wood-Gasifier)

tatebullrider 

In this Instructable I will be showing you the steps I used to build my Wood/Biomass Gasifier. It was really a fun project and I would encourage anyone serious about preparedness to build one. Now in case you don't know what a Gasifier is (and don't feel bad if you don't as very few people do lol), they are quite simple, let me explain. Essentially all gasification is, is a form of incomplete combustion, heat from the burning solid fuel creates gases which are unable to burn completely because of the insufficient amounts of oxygen from the available supply of air, it then filters those gasses(which is by weight: 20% hydrogen, 20% carbon monoxide, 50 to 60% nitrogen, and a little bit of methane) And you can really use any kind of Biomass(organic material) that will burn. You can even use things like paper, coal, peat, and lignite. You can then use that filtered gas to run any thing from a generator to a car. So now that you have a basic understanding of what gasification is, lets get down to the build!!!

DIY: An Ultra portable Torch knife

pocholox8  

Hey guys! so its been a while since i've written an ible and i must say, its great to be back! Seems like there's a ton of great instructables recently popping out and i hope this one makes it to your list of favorites ;)

Anyhow, here's a short read about how it was made..

As i was working on my cotton candy machine, here's a little list of problems (aka:opportunities lol) i had encountered back then

Due to the lack of tools at home, i really found it difficult to cut the hard plastic enclosure into a decent circle until i tried heating a retractable cutter blade with a lighter and to my not-so surprise, it worked quite well! but then an idea sparked from that simple combination of tools, what if i built a heating system that could be mounted on a cutter? after a handful of developments and instantly cauterized cuts on my thigh, i finally realized an x-acto™ knife would do the perfect job! Both aesthetically and functionally.

Revolutionary 3D printed magnets by Polymagnet can change engineering as we know it 

Alec 

We’ve all played with magnets when we were younger. And to a kid, they are pretty magical with one attracting and one repelling side – until you find out about magnetic fields in high school. However, those conventional magnetic are actually quite limited, as the pioneering work of Correlated Magnetics Research (CMR) proves. The startup has been working on revolutionary new magnets, featuring 3D printed magnetic fields called Polymagnets that can be customized for any purpose – from very tight magnetic twisting seals to ‘magnetic’ springs that seem to float thanks to equal amounts of attraction and repulsion. A technology that can change engineering as we know it.

E uma Dica que é um Instructable, se precisam de reparar alguma peça, ou criar até uma peça pequena em Plástico, eis Plástico Instantâneo...

Basta juntar Maizena!

Ou, dizendo melhor, juntem Super-Cola a Maizena, e terão um Plástico que podem furar, , lixar, cortar e maquinar, para o que der e vier!

Bom para Modelismo, acabamentos em Protótipos, etc. 

Também poderão fixar estruturas desmontáveis, para terem Impressoras 3D mais rígidas digo eu. 

Superglue Hack!

Weaving baskets with newspaper

dezine

I have just discovered how easy it is to weave a basket using newspaper! It's so simple to roll paper tubes out of newspaper and then weave the tubes into a basket. You can bet I will be making plenty of these faux wicker baskets for future projects, as well as for storage in the home.

I discovered this post on a Russian website and the instructions don't quite make sense, so I started putting together my own paper weave basket using newspaper that I normally keep for cleaning windows and messy projects.

Impecável. 

About

Bondic® - The World’s First Liquid Plastic Welder. 

How many times has glue let us down? Fingers stuck together, broken toys that we just can’t fix, having to throw out our stuff because gluing it only made it worse. Not to mention just when we need glue most we discover our 3-month-old bottle is as dry as the Sahara Desert on a hot day.

Bondic® is the only product that works where glue fails. It’s liquid plastic that only hardens when you need it to. YES it stays liquid and won’t dry out like those crazy glues on the market today. Bondic® is a very simple 4-step process (clean, fill, cure and shape) to fix almost anything, saving countless precious items from ending up in the trash before their time.

Never again will we be at the mercy of sticky, messy and exasperating adhesives that do anything BUT what we need them to do. We live in a plastic and disposable world today, so much so that Ken and Barbie almost look human in comparison. Our mission is to save expensive items and hard earned money by not having to replace them every year or even every month! Oh and while we’re at it, contribute to shrinking a landfill or two.

Ora isto também é fantástico, Dica do nosso amigo Eddy de Ridder, para ser usado em de tudo um pouco!

Não há realmente, como testar as coisas no mundo real, e aqui está como saberem se um Móvel que imaginaram é aquilo que querem ter, mesmo, ou não...

Mas pode servir para desde espectáculos ad-hoc, até Hangares temporários para Aeromodelismo, passando por Hexacópteros mesmo grandes, e até para Auxiliar temporário, quando não há ninguém para segurar nisto ou naquilo, quando montam ou consertam algo!

E tudo isto, feito com Fita Adesiva, que se enrola num Tubo!

Protopiper: Physically Sketching Room-Sized Objects at Actual Scale 

Harshit Agrawal, Udayan Umapathi, Robert Kovacs, Frohnhofen Johannes, Hsiang-Ting Chen, Stefanie Mueller, Patrick Baudisch 

Protopiper is a computer aided, hand-held fabrication device that allows users to sketch room-sized objects at actual scale. The key idea behind protopiper is that it forms adhesive tape into tubes as its main building material, rather than extruded plastic or photopolymer lines. Since the resulting tubes are hollow they offer excellent strength-to-weight ratio, thus scale well to large structures.

Transforming Workbench & Storage

polyglot45 

My girlfriend is an artist and has been infinitely patient with the fact that our previous living situations have prevented her from having a nice and functional studio space at home. We bought a house earlier this year which meant that we were no longer living under the constraints of a tenant-landlord-no-major-alterations relationship and we were free to do as we liked. She was away for about a month this summer, during which time I overhauled the room we had designated as her studio space. Though she knew it was happening and had given me some parameters, I was allowed considerable creative license in the renovation. Buuuut, old habits die hard and I tackled the redesign with the knowledge that we will likely move SOMEday and maybe a home studio might not be a selling point for future buyers and maybe she'd like it so much she would like to take it with us. So I set about to create something big and amazing yet still portable. (In all honesty, this project will leave considerably fewer holes in the walls than most other shelves I've installed in apartments....so have no fear!)
