Reverse Engeneering! E ainda mais funções 3D, Realidade Virtual para a Mecânica, e uma faca duma lima!

E se vos dissesse que podem fazer Reverse Engeneering das vossas peças, isto é, podem pegar no Scan 3D duma peça, e transormar isso num Ficheiro CAD?
E isto numa versão-teste dum Plugin para o Rhino... Grátis?
Pois aproveitem, que não vai durar sempre:

Data from measuring machine, laser scanner or touch probe: Transformation to high-quality NURBS faces.
Test it now for free
Rhinoreverse – The plug-in for Rhino for reverse engineering!
  • Accurate CAD data not available? – RhinoReverse provides a quick solution: Import point clouds, STL data and polygon meshes to Rhino – RhinoReverse quickly transforms them into NURBS faces.
  • Easy to use – fast results – With the buttons of your mouse you can easily and intuitively create NURBS faces. Just sketch curves on the mesh and RhinoReverse will automatically fit NURBS surfaces to mesh.
  • Reuse data in the CAx process chain – Prepare your data for the use in further design steps of the CAx process chain. The integrated healing function ensures that the resulting surface model can be used afterwards for solid operations on NC programming without any rework.
Create NURBS faces from mesh data – easily in Rhino!


Agora, existe mais uma Scanner/Impressora 3D, mas esta ainda por cima, vos fresa Material em 3D, fabuloso!
Com a possibilidade de adicionarem peças de outras proveniências, e sem rolos epeciais de plástico, é muito tentadora, esta maquineta...

3D print, mill and scan with the FABtotum hybrid fabrication machine

Heidi Hoopes

If you’re in the market for a personal fabrication machine, you probably already know that your budget might allow for a 3D printer or a CNC machine, but not both, and an additional 3D scanner would just be icing. However, all three are now available together on Indiegogo in the form of the FABtotum, one of the first hybrid fabrication machines in a quickly developing market.
I'll explain the name right off: in Latin, a factotum is a human servant responsible for many different things, literally doing and making everything.
This FABtotum, however, is a shiny and neat 36-cm (14-inch) cube available in many color options. The maximum printing size is 210 x 240 x 240 mm (8.3 x 9.5 x 9.5 in), which is large proportionate to its overall footprint. Tools can be easily swapped out and the company will allow third-party tools and parts to be sold on its website – no proprietary spools of printing material to buy, or expensive upgrades.

Eis uma Aplicação para o vosso Smartphone, que vos transforma em Mecânicos de Automóvel, por meio da Realidade Virtual, no que eles não irão pensar a seguir!



Anyone Can Be a Mechanic With I-Mechanic Augmented Reality App

Car engines and equipment can be a totally unknown universe for many of us. Even if you are a longtime driver with your hands on a new car, you might not know where in the engine the most relevant parts are exactly located. Not to say when you have little or no experience at all and you are finding yourself in the middle of nowhere in need of help on how to refill your engine coolant. With this mobile application, based on an innovative computer vision 3D tracking software, anyone will be able to contextually access the instructions required to maintain their car, where is needed when is needed.

E para terminar, por hoje, eis uma maneira de aproveitarem uma Lima para fazerem uma Faca, algo em que, confessem, já pensaram...
Pois agora, há um Instructable, para fazerem mesmo isso, passo-a-passo, e com as ferramentas que já têem.
É bom!

From File to Knife (with simple tools)


A good "bushcraft" knife is a must-have for every outdoorsman.
It's a tool that lasts a lifetime.
Wouldn't it be awesome to make such an essential, lasting tool yourself?

There are many different types of knives and many ways of making them.
This instructable will show you how to make an excellent, inexpensive (<$20) bushcraft knife with simple tools (such as a hacksaw, file, drill and vice).
The design is based on the popular (but expensive) Ray Mears Bushcraft knife.

So if you have a few basic tools and plenty of elbow grease, lets make the [Your Name Here] Bushcraft Knife :)
