Parafusos 3D! E construír Circuitos, mais uma Impressora 3D Open-source, e testem a Impressora!

Um Parafuso faz falta... 

A muita gente! 

LOL

Por exemplo, nas vossas Engenhocas, pode ser importante imprimir em 3D uns parafusos, mas uns que funcionem, mesmo, sem falhas, e com dimensões e outras características que não encontrem por ai.

Por isso, sigam este Tutorial:

 

Step-by-step easy guide: designing and 3D printing threads
Katarzyna Plewa

In this blog post, we will show you how easy it is to 3D model threads, which are used all around us. We have them in our bathrooms, kitchens, gardens. Most of them have universal size and can be easily designed and 3D printed with an online service like Sculpteo. Our 3D printing experts will show you how simple 3D modeling and 3D printing can be. Let’s get started!

What are the benefits of 3D printing threads?
One would ask, why would you 3D print threads if they are already available on the market? But the benefits of 3D printing threads are numerous. Let’s start with the customization. No other technology in the world gives you that much design freedom and a high level of details. With Additive Manufacturing you can design and produce parts perfectly fitting just your needs.

Para perderem o medo a criar os Circuitos Electrónicos, que precisem, aprendam com este Instructable, porque aprendendo, o que custa mais, é dar os primeiros passos:

How to Build Your 1st Circuit

Building your own circuits can seem like a daunting task. Circuit diagrams look like hieroglyphics and all those electronic parts make absolutely no sense.
I have put this Instructable together to hopefully help and guide you to ultimately build your own circuits. The 10 tips in this Instructable are ones that I have picked-up over the years through much trial and error. I’m no expert (the great thing is you don’t have to be an expert to learn how to create circuits!) so please don’t expect this Instructable to be a complete guide. Rather, I hope it’s used to help anyone who is interested in learning about electronics and circuits, to pick up a soldering iron and get started.

Mais outra Impressora 3D Open Source, para não dizerem que vos faltam opções, e este, com práticamente tudo o que é bom, mas ainda assim, com a possibiliade de ficar melhor!

LightBlue 3D
fkirita

Hello.
In the past 4 years I've played with 3D printers.
I have discovered and learned new skills and knowledge. I designed and printed a lot of objects. I fell in love with 3D printers. And I hated them. And again I fell in love.
And now I've decided to make a 3D printer. An open source printer.
In this instructable I will describe how to build your BlueLight 3D printer. It is the first 3D printer we produced and is the basic model. If you want, you can upgrade to DeepBlue 3D or even to DeepBlue 3D Pro.
Highlights: cube like frame, new cross XY rolling system design, servo Z probe for all bed surfaces, four point translation bed design, simple filament run out sensor, active cooling with laminar air curtain and Marlin 2.0 firmware (early stage).
The DeepBlue 3D Pro, the top of the Blue3D range has an active enclosure, wi-fi connection, raspberry pi with octoprint and direct extruder.

Um Diagnóstico completo à qualidade das vossas Impressões, é o que vos oferece este fichheiro que é um Teste de Impressão, bem mais completo do que o simpático Benchy:

Autodesk and Kickstarter Develop a Free, Downloadable Universal Test Print for 3D Printers

Rain Noe

Before buying one, how do you determine if any given FDM (fused deposition modeling) 3D printer will be able to do what you need it to? Shouldn't there be some universal test print, like those printer test pages that you can use to determine if your printer's up to snuff?
Kickstarter thinks so. As the host for over 200 successfully-crowdfunded 3D printers, most famously Formlabs', the company realizes it would be beneficial if all developers of 3D printers could demonstrate their machines' capabilities by all producing the same complicated object. Hence they've partnered with Autodesk to develop the following file:

É bom!

Extruder Calibration – 6 Easy Steps
Emmett Grames

Extruder calibration is crucial to FDM 3D printing for many reasons. The point of extruder calibration is to ensure your printer is pushing exactly the right amount of filament through the hot end during a print.
Too little filament and a part will have gaps between layers, or the layers themselves will be weak or missing. Adhesion will also not be very good, and prints can be subject to layers delaminating and warping.
Too much filament and your prints will come out with over-extrusion problems, resulting in blobs, stringing, and droopy details. Extreme over-extrusion can also contribute to clogging and filament jamming in the hot end.
To avoid these problems, we suggest following this simple step-by-step guide to calibrate your extruder.
