NASA em 3D, manejar Ímanes MESMO fortes, e KISSlicer

Já podem imprimir em 3D os vossos Modelos de Sondas Interplanetárias, e alguns Asteróides, e Paisagens Planetárias.
Não, o Modelo do Módulo Lunar Apolo ainda não lá está, nem sei se estará em breve, mas a Soanda Voyager, sim, já a podem imprimir.

NASA releases 3D-printable models to the public

David Szondy

If you have access to a 3D printer, then you can build your own space fleet courtesy of NASA – provided you don’t mind spacecraft that are plastic and four inches long. As part of its continuing program of education and outreach, the space agency has released 22 printable models of NASA and European space probes, asteroids, and planetary landscapes for the hobbyist and space enthusiast.

The 3D models are available from the NASA website for free and are printable on any desktop 3D printer using plastic filaments. It’s the latest in a long tradition of NASA science, technology artwork made available to the public going back to its founding in 1958.

Os Ímanes em Neodímio não são brincadeira, e podem-vos esmagar um dedo ou dois, se manejados distraídamente!
Para evitar isso, aprendem com quem sabe, a separá-los, e a juntá-los:

How to Separate Strong Magnets

Neodymium magnets are strong. Really strong. If you have never handled neodymium magnets before, you will be surprised at their remarkable strength. They're not the ceramic magnets you find at craft stores.

Whether talking about relatively small magnets like 1/4" diameter D41 discs, or monstrously big block magnets like our BX8X8X8, separating these magnets can prove challenging to those without experience.

Here, we share some of our strategies and tips for separating strong neodymium magnets.
The Basic Idea

Neodymium magnets pull towards each other with a strong force. If you try pulling two magnets directly apart, you need quite a bit of force to pull them apart. To separate one magnet from another, you'll need to pull with a force equal to the listed Pull Force Case 1 number.

This can be difficult if the magnet is strong, or if there isn't much area to grab onto the magnet. Most methods of separating these magnets do two things:
They provide more leverage and/or a better way to grip the magnets
They move the magnets apart laterally (sideways), which requires less force


Dica de Affonso Orciuoli, eis como operar o KISSlicer, que vos transforma os vossos Objectos em 3D, em G-Code, pronto para a Impressora, Fresa, etc.

Introduction to KISSlicer


This is a brief overview of KISSlicer settings. I cover what most of the fields mean and show how to select a file to slice and placement on the print surface.
