Kappius Components uses laser sintering from EOS for trailblazing bike-hub/drive assembly
Carlos Garcia Pando's insight:

It is very difficult for me to accept calling an EOS Metal machine a 3d printer. I can understand that you call a Z-Corp  machine a printer because it has "printing heads". Obviously an MCor one, or even an Objet because it has injectors.

But don't create false illusions on 3d-printing, as the majority of things you are calling 3d printers are the fused filament cheap things, in the $500 to $50.000 and none of them will ever be able to "print" this high quality Al parts for a hub.

This said, another example of Additive Manufacturing in a very demanding part is having success and makes life easier for a struggling startup.

The company is Kappius components

Next to Use 3-D Printing: Your Surgeon

Next to Use 3-D Printing: Your Surgeon | Additive Manufacturing News | Scoop.it
Surgeons are finding industrial 3-D printers to be a lifesaver on the operating table. This technology, also known as additive manufacturing, has long produced prototypes of jewelry, electronics and car parts.
Carlos Garcia Pando's insight:

I would change it to: "Didn't you know that your Surgeon already uses it?"

When I first heard about Rapid Prototyping (as every layered technology  was called then) the first example everyone told you about was the case of Dr. Henry Kawamoto's conjoined tweens.

http://www.turkcadcam.net/rapor/otoinsa/uyg-medikal-conjoined-twins.html

 But there have been others before: http://www.nyp.edu.sg/seg/working-with-industry/industry-services/medical-prototypes-for-siamese-twins.

 

I would say that this is not yet, but it is close to being mainstream.

 

The innovation in this case is teh use of other materials that give a wetness and texture of a real human liver, making it more suitable to cut with a surgical knife.

Another misleading headline: "How doctors printed my new face"

Another misleading headline: "How doctors printed my new face" | Additive Manufacturing News | Scoop.it
A man has had a new face printed for him after he lost the entire left side of his face in surgery to remove a tumour.
Carlos Garcia Pando's insight:

Once again, a "not-true" story makes a fool of all of us using the 3D printing hook to engage the story.

This is disappointing. The actual procedure was:

*   Scanning his head to a 3D file

*   Mirroring the good side to complete the missing bone and face

*   Milling the necessary bones and screws out of  a Ti billet

*   PRINTING a model of the skull to help make a plastic seal for the mouth

*   PRINTING a polyamide shell to cast silicon into the actual facial mask

 

So despite the interesting applications the headline is absolutely misleading.

Another similar story is http://sco.lt/5iwIKX and this other overrated headline http://sco.lt/95N5jV

On the opposite side we can find these true stories or genuine results: http://sco.lt/7cWogT and http://sco.lt/8qgLkf

3D Industries offers 3D Search: search by shape

3D Industries offers 3D Search: search by shape | Additive Manufacturing News | Scoop.it
Imagine being able to search for components, supplies, designs, industrial parts... using shape and geometry alone. Imagine the ease of no longer having to use vague keywords that differ between companies and countries. Imagine the end of language barriers, misunderstandings and inaccuracies.
Carlos Garcia Pando's insight:
Try it and you won't believe it. While having all that variety and potential floating around out there isn’t a bad thing, it can make finding a supplier that happens to have (and can produce) the same kind of model as the one you need something of a challenge. Naming is part of the problem. What I call a square, you might call a block. If I try Googling service bureaus that can print squares, I’m not as likely to find exactly what I need. 3D Industries (3DI) intends to solve this issue with its new part search service. "What Google did for words and text on the web, we aim to do for shapes and 3D models,” said Dr. Seena Rejal, the founder and CEO of 3DI. “We are ordering the 3D world.”

Rapid Prototyping Continues To Explode While The Stocks Take A Breather

Rapid Prototyping Continues To Explode While The Stocks Take A Breather | Additive Manufacturing News | Scoop.it
The 3D printing and rapid prototyping sector entered 2013 as one of the hottest sectors.
Carlos Garcia Pando's insight:

While ExOne (XONE) had a splashy IPO during February (see Does The ExOne IPO Offer Any Value?) and private Mcor Technologies made an attention grabbing announcement with Staples (SPLS) (see Staples Fires Warning Flare To 3D Printing Market), the public markets are still dominated by 3D Systems (DDD) and Stratasys (SSYS) with market caps approaching $4B. 3D Systems remains the serial acquirer that has the largest revenue and the most questioned organic growth rates. Stratasys merged with Objet to create an industry leader of scale to compete with 3D Systems.

NZ's Customs Minister is Worried About 3D printing

NZ's Customs Minister is Worried About 3D printing | Additive Manufacturing News | Scoop.it

Customs Minister Maurice Williamson says he is extremely worried about what 3D printers will do to border security.

 

Carlos Garcia Pando's insight:

In this interview Mr Williamson mentions two recent press highlights: " 3dprinters will become as common as PCs" and "anyone could print drugs and weapons", so he has asked his officials to think hard about how to keep up with this kind of technology before it becomes an actual border security threat.

 

We know that theres still no way to cheaply print drugs on demand, or working weapons.

Soft tissue prostheses production using 3D colour printing

"For patients requiring the fitting of a soft tissue prosthesis, such as an ear or nose, the process of making and fitting prostheses are archaic at best" commented Professor Ric Van Noort of the University of Sheffield. 

Carlos Garcia Pando's insight:

This is the counterpart of the previous post. In this case, they produce the replacement part directly in a colour Z-corp machine. The part is then infiltrated and covered with a soft biocompatible material that can be worn to replace a missing nose, part of the face, ears, etc.

 

The development of the industrial process also took into account the data capturing technology, separating the colour information technique (any consumer photo camera will do) and the 3D scanner: there are several cheap scanners in the no-color range, but those which also capture colour are very expensive.

Collagen is the main component of animal connective tissues; organized in fibers. This is the inspiration to create these masks with a dedicated software after 3D scanning the face

Carlos Garcia Pando's insight:

Aesthetical sense is always personal, and thus arguable, open to discussion.

I have to say that I both like and dislike the results. But what if we could print in light collagen, or higly resistant nanocellulose?

South Africa to Launch Large Scale Additive Manufacturing Production

South Africa to Launch Large Scale Additive Manufacturing Production | Additive Manufacturing News | Scoop.it

With the aid of government investments, AeroSud has launched Project Aeroswift. The end goal of the project is to create an AM machine that is capable of printing out parts as large 6.5 ft. x 1.5 ft. The South African National Laser Center has pitched their aid to the project by creating a 5 kW IPG single-fiber diode laser to use in the laser sintering machine. The primary material used will be powdered titanium

Carlos Garcia Pando's insight:

This is not only great news, but "big size" news for the AM community. Just while I was shocked watching a metal laser sintering machine for the first time in my life, back in 2004 at EUROMOLD, I had a vision of the same technology building huge parts in a 200 x 50 m industrial building, with high power lasers running on overhead travelling cranes.

 

Now we see an explicitely formulated project for building Ti parts in the more than 1m range, leaving apartSciaky's moving EBM gun to produce parts in the 5.7 x 1.2 x 1.2 m  http://sco.lt/7wwgOf

Wrong again! This is misleading information

Wrong again! This is misleading information | Additive Manufacturing News | Scoop.it

Snowboards have traditionally been made of wood, resin, laminates, and P-Tex—until now! The Signal Snowboard’s factory crew print out a brand new snowboard! Using new 3D printer technology, Dave Lee and Signal Engineer Jeb Ferria input a basic CAD drawing along with a carbon-based powder into a state of the art Connex 500 printer—the end result is a radical snowboard ready for riding in the steep and deep of Colorado.

Carlos Garcia Pando's insight:

The idea is great.

 

But anyone watching the video after reading the post will be confused. Objet machines (the referred Connex 500 from 0:53 to 0:58) do not work with powder, be it carbon or other; they work with UV light photo curing resins. They are actually using a laser sintering process.

 

Besides this, you see that someone "designs" a part, builds it, assembles and then it is not what they expected. They have to do a little DIY, a couple of bolts, bars and anything else to make it resistant. It makes clear that there has been only a DRAWING process, not a proper design.

 

It's a pity.
