Moldagem por Ultra-som! E um Inventor Brasileiro vende, mais uma bancada para o torno com rodas, e Objectos 3D à farta

Isto vai dar que Fabbar, porque muito Fab-Lab vai querer pôr as mãos nesta Máquina, um Moldador de Plástico, não por Injecção, mas por Ultra-Sons!

Resulta num método de fabrico muito mais eficiente, e capaz de mais detalhe que a Injecção de Plástico, e já imagino que um dia vá ser vendida uma versão caseira, ou algum Hacker vai imaginar algo parecido, Open-Source...

Ultrasonic medical molding machine reduces energy consumption 

Stu Robarts

Injection molding is the widely preferred method for shaping plastic medical components, but now a new type of machine promises to slash energy and materials costs. Ultrasion's Sonorous 1G uses ultrasound to produce highly targeted and efficient heating to melt its plastic base material.

The Sonorous 1G was on show this week at the Medtec UK, a trade exhibition for medical technologies and devices. Despite its uses in the medical sector, it has uses in a host of different industries.

Research into technology used by the Sonorous 1G began about six years ago, with European Commission funding and help from the Barcelona-based ASCAMM technology centre. ASCAMM spun off Ultrasion as a company to take the technology commercial.

É sempre bom ver um Inventor que vende, e este Colega Brasileiro vende mesmo, na Net, o seu Produto, um Abre Latas e Garrafas multi-funcional::

 

Ksplash o Abridor Multifuncional 8  em 1.

​Ksplash o abridor multifuncional.

Desde de o inicio da humanidade, o homem vem observando o mundo que o cerca e, constantemente pensando em como facilitar sua vida, face as dificuldades o aflige.
É desta  busca por  soluções lógicas e praticas que evolui a humanidade.
Observem as grandes ideias que sacudiram o mundo, fazendo com que a vida na face da terra ficasse mais leve, agradável, simples, sem sofrimento.
...
E as grandes ideias não se traduzem necessariamente em produtos grandes, mas sim em grandes produtos, tais como garrafas Pet, embalagens Tetra Pak, latas de alumínio para bebidas, etc.
E, mais uma vez, a observação do dia a dia gerou uma ideia genial que se transformou em um grande produto, o Ksplash.
Neste exato momento, no mundo todo, milhões de pessoas estão abrindo uma lata de refrigerante suco ou de cerveja ou uma garrafa Longneck e tentando rasgar saches de catchup mostarda e maionese
Mulheres lascam ou estragam os esmaltes das unhas, homens ficam com marcas nos dedos e nas mãos abrindo Longnecks, utilizando ou as mãos ou outros processos mecânicos e as vezes não higiênicos. Saches muitas vezes tem que serem  abertos com os dentes, por não terem picotes eficientes .
É ai que entra o Ksplash, com toda a sua eficiência e simplicidade para facilitar de vez a utilização destes recipientes.

Bela ideia, fácil de executar, e ainda por cima, pode ser fácilmente desmontada!

Anti-Wobble Wheeled [Lathe] Table

BoilingLeadBath

When neither a 4-leg nor a 3-leg table will do, a simple suspension allows us to combine some of the best attributes of both: the wobble-free performance of the three-leg table and the high tipping energy of the standard four-leg.

We couple this suspension with a table built for stiffness, a table-top mini-pallet to make it easy to disassemble the thing into parts which can be carried, and a set of cheap, strong, drawers which will stay put while you wheel the whole thing around.

Overall, I'm pretty happy with the way the design has worked out. There's a few compromises (see Design) which you might want to reconsider, depending upon your facilities and needs.

The tables take about 10-15 hours to construct, including one drawer, using a circular saw, a table saw, a radial arm saw, a drill, a pneumatic staple gun, screws, glue, and staples. This time could be reduced substantially with a nice table to do the construction on, and a panel saw or big table saw.

Bicycle Frame Building Jig 

Tanner W

A little over a year ago I took a bicycle frame building class through the United Bicycle Institute. I attended the chromoly brazing class at their Portland campus. Since then I have wanted to build more bike frames. I am interested in making money doing it, and perhaps someday, making it my sole source of income. On the path to becoming a bicycle frame builder one of my biggest obstacles is acquiring a frame building jig. They are expensive, arguably the most expensive single tool you need to accurately build quality bicycle frames. So I, like many bicycle frame hobbyists, decided to build by own. My personal goal for my frame jig however, was to build a professional quality frame jig. I wanted something I could potentially start a business with.

Como ver ficheiros CAD, sem programas CAD?

Com este programa, que tem uma versão de teste Grátis, que tem a possibilidade de se exportar para o formato JT:

Highlights of KeyView V12

• The absolute highlight of KeyView 12 is the new add-on module for JT export.
  JT is a compact ISO-standardized, neutral data format. It is often used in application processes after geometry creation. Teamwork is possible regardless of a CAD system.
• Display of meta-data and other enhancements in the structure-tree
• KeyView V12 is significantly downsized and reduced (approx. 40% smaller). Save valuable time during installation and download as well as space required.
  
  Further innovations:
• New Installation routine
• New „Silent“ Installation (MSI-file)
• License activation through WEB for Floating Licenses
• Quick Open and Precise Open are merged into one
• Update of Importers
• Import of CADDS 3D files
• Improved CGM Export (specially for technical documentation)

Ultrasonic measuring tape

This time I will try something new. To make sure I don't forget about important steps of the build process, I will write the instructable while I am soldering, making measurements, locating software bugs. Hopefully this will allow everyone to follow what I have to say, and why I am saying it. Let's start with the stuff I put on the table now, at the very beginning.

How to Make Homemade Ultrasonic Cleaner Solvent

An ultrasonic cleaner is a cleaning devise that helps to clean delicate and hard to clean items using ultrasonic and cleaning solution. Ultrasonic cleaning is the most effective method of cleaning and can be easily incorporated into any industry as well as home.
Ultrasonic cleaning is not only meant for industrial use. It is widely used for cleaning, fragile, delicate items like jewelry, watches as well as cleaning stubborn dirt. Portable ultrasonic cleaners are boon for home makers cleaning which uses ultrasonic cleaner solution to clean the items effectively.
Ultrasonic cleaners use high frequency sound waves to agitate the cleaning solvents. This in turn makes the ultrasonic cleaner solvent particles to clean dirt from the substances with a very high speed. Thus, even stubborn stains could be completely eliminated.

E o Brasil está de parabéns, Cientistas de lá conseguuiram um Anti-Inflamatório para a Dor Aguda:

Brazilian researchers develop new anti-inflammatory for severe pain

By Antonio Pasolini

Researchers at Butantan Institute in São Paulo, Brazil, have developed a powerful new anti-inflammatory to relieve hard-to-control pain. Initial tests have confirmed the efficacy of the medication, which is based on a protein found in the blood.

The main breakthrough of the research is the successful synthesizing of a protein produced by the human body, the calcium binding S100A9. Under certain conditions, this protein is used by our bodies to keep pain under control. To make the medication, the scientists discovered that only a small part of the protein is required, which leads to reduced production costs.

According to researcher Renata Giorgi, the discovery represents an important step forward in relation to drugs available in Brazil. In particular the new drug offers two important advantages: it is more powerful and it can be administered orally.
