A 3D printing update for you

Manufacturing Materials that Can Be 3D Printed

3D printing entails building objects in three-dimension from a computer-aided design (CAD). In the printing process where sophisticated forms of printing are used, the material is added successively layer by layer. This is the reason why 3D printing is also referred to as additive manufacturing.

Many processes like presses, hammering and casting are involved in conventional manufacturing. But with 3D printing, materials are added in layers, hence making it more convenient to create objects as compared to manufacturing them conventionally.

It is only a matter of time and 3D printing will replace traditional manufacturing and assembly of products. With 3D printing, it is possible to get industrial prototypes and final products with utmost precision.

3D printing is synonymous to speed and optimisation in that objects are made in record time with efficiency and in a tidy working space, as opposed to traditional forms of manufacturing.

This process entails fusing of molecules and powder grains layer after the other. The layers are then solidified under computer control, resulting in a three-dimension product. Companies like Geomiq can even complete your project in 3 days.

Mobile telephony, aerospace and automotive industries are among those that have adopted this new form of production to create parts and crucial component. It ensures that parts are replaced, modernised and upgraded with new functionalities and components.

Some of the advantages of printing products in 3D over manufacturing them traditionally are as follows:

  • 3D printing is useful in training and consulting experts for new products and projects.
  • It helps in surveying and digitizing real parts.
  • It helps in remodelling and re-engineering.
  • It helps in faster production of prototypes in new inventions before mass production.

All spheres of life require 3D printing and have already started reaping the benefits. For instance, the medical world is about to revolutionize organ transplant by availing some of these body parts through 3D printing. Parts like skin, limbs and kidneys are now available thanks to 3D printing.

Even the new space technologies are utilizing 3D printing such as Stargate’s Terran 1, the world’s 1st 3D printed rocket. Stargate’s patented technology gives way for an entirely new chain that made Terran1 possible.

Complex geometries can be fabricated as well quickly, in a reliable manner, and with lots of flexibility, regardless of the size. 3D printing comes with the benefit of low operational costs as compared to conventional manufacturing processes, which are typically expensive.

When one invests in an effective and affordable 3D printing solution, they are assured low-cost production and efficiency.

Statutory requirements and improved conditions of work coupled with customer satisfaction and changing trends and designs are all guaranteed by the use of additive manufacturing.

In addition, it is possible to redesign old data from drawings or even artefacts. To do this, you will first have to convert the old data to CAD data to provide the raw material for 3D printing. Once that is done, you will be able to create the exact product as the old one.

3D printing, however, requires a bit of conventional manufacturing to finish printed objects either by the assembly, milling and cutting by use of machines before getting the final product.

Physical projects are converted into digital models through 3D laser scanning, which allows quick and accurate capture of shape and geometrics. This provides a digital form to be used in the additive manufacturing process.

This improved invention of paper printing is very resource-efficient by the fact that it has minimal or no waste at all as compared to conventional manufacturing. This automatically makes it cost-effective.

Contrary to traditional supply chains which would rely on the efficiencies of mass production and require many assembly workers, 3D printing requires very little work.

Additive manufacturing, however, has its shortcomings, especially when it goes past the prototyping stage.

One disadvantage is that, unlike traditional modes of manufacturing which recreate products with high speed, additive manufacturing is slower. This is because every product has to be produced in layers and the process has to be repeated for all the parts which may take hours.

The use of specific materials also requires different models of 3D printers which are specifically designed for those materials. A lot more innovations are required in 3D printing because some materials still can’t be worked on a 3D printer such as metal alloys owing to their high melting points.

Research and innovation are, however, ongoing to make advanced inventions of 3D printers. This could only mean that the future holds a lot about additive manufacturing.

Conclusion

3D printing is creating new possibilities in many fields. The process is quite fast and accurate, and that allows people to create prototypes easily before mass production. 3D printing or additive printing is quite efficient and cost-effective.

How to convert a medical scan

As you may know our team here at 3D Filaprint are always researching and learning so that we can pass that knowledge on to the 3D Printing community.

This month we have found an extremely fascinating item on how to convert a medical scan into a 3D Printed Model.

Using data in a DICOM format we learnt how to turn data from a CT or MRI scan into a 3D printable model. The information from Instructables uses a dinosour skull for this informative presentation.

Using a software package called Osirix, which is designed for medical imaging, you can convert the format and create your own 3D Model of your scans. Download and install the free version from here. It is available for Mac only, if you are using a PC check out a similar package called Invesalius, developed by the Brazilian government and made available for free.

We’ll also be using Meshlab and Netfabb Studio Basic. You can download the software using the links. It’s all free.

Why don’t you give it a try and post your prints on our Facebook Page.

Limb Saving 3D Bones

Thanks to ABC Down Under we can bring you this most amazing story of  limb saving surgery.

The first person to have a 3D-printed tibia transplanted into his leg says he cannot wait to put it to good use by walking his fiancee down the aisle.

According to Brisbane’s Princess Alexandra Hospital (PAH), Reuben Lichter had become the first person in the world to have a 3D-printed tibia or shinbone transplanted into his leg.

It has taken five operations over the past six months — the final one lasting 14 hours.

The 27-year-old developed spontaneous onset of tibial osteomyelitis, an infection of the bone, which resulted in the majority of his tibia – 36cm – being destroyed.

Normally, the only option is an above-knee amputation.

“Doctors came up to me and said there are two options — you can get amputated above the knee or we can try this experimental stuff that may or may not work,” Mr Lichter said.

“I was like, ‘bang, let’s do it’.”

Mr Lichter said his dream now is to walk his fiancee Caity down the aisle.

But he will have to wait a while. Doctors say it will be at least 18 months before he can walk again.

Mr Lichter said his young son William would be walking before he does, but he is set to take his recovery one step at a time.

The 3D-printed model was manufactured in Singapore.

It is wrapped in biological tissue which then engineers the new bone.

A human tibia bone lies to the left of a 3D printed tibia bone.

Health Minister Cameron Dick said it was like scaffolding that supported the biological tissue.

“That then grows effectively a new bone in your leg and this is the first time this has been done,” Mr Dick said.

“We’re not out of the woods yet, there’s a lot of recovery to go through but [Reuben] is very positive, he’s very happy the pain has disappeared and the infection has now gone and he’s living very positively with the future.”

This is such an amazing story and one that we hope can be replicated around the world as 3D Technology begins to evolve further into the world of medical science.

We wish Reuben all the very best for a good recovery.
