Based in Haarlem, Netherlands, ElogioAM will provide its high-performance FFF Facilan filaments for medical applications, as well as its new dental grade filament, Facilan Ortho.
“We’ve developed this material in concert with orthotics producers, orthotics fitters and people who wear orthotics in order to develop the perfect filament for 3D printing orthotics,” said Ardy Struijk, Sales Manager at ElogioAM and Director of Sales Marketing at 3D4Makers.
“Facilan Ortho is intended to provide for more comfortable orthotics materials that are softer, better fitting, adhere better to textiles and are more comfortable than existing materials.”
The Facilan filament family
Earlier this year, Perstorp and 3D4Makers announced the beginning of a materials partnership to address the demand for more reliable FDM 3D printing quality.
With over a century of experience in polymer chemistry, Perstorp has aided 3D4Makers in making the Facilan range of thermoplastics. The Facilan C8 filament has a higher tensile strength when compared to ABS and PLA filaments, and prints without visible layers. C8 also has the increased adhesion properties and surface quality of any FDM material.
Medical-grade 3D printer materials
Facilan Polycaprolactone (PCL) 100 is designed for advanced applications such as medical research. According to ElogioAM, Facilan PCL 100 has been used by universities to develop artificial tracheas, scaffolds for tissue engineering, and bioabsorbable implants. With a low print temperature of 120°C, this material can be reshaped after 3D printingin water with a temperature of 55 °C. This allows for form-fitting applications such as medical braces.
The newest addition to the Facilan range of filaments is the Facilan Ortho. This polyester is a semi-crystalline material that maintains a clean white finish. With a high adhesion towards textiles as well as reshaping properties, this material is designed for soft and corrective braces, and shoe soles.
In addition to its Facilan filaments, ElogioAM is currently building an Additive Manufacturing Database to increase the knowledge of new consumers adopting 3D printing technology.
Dr. Song Hongxin, an ophthalmologist and researcher at the Beijing Tongren Hospital, China, has 3D printed spectacles to help patients with deformed corneas.
The 3D printed optical lenses are designed specifically to treat keratoconus, a progressive eye disease which deforms the cornea. The idea is that a 3D printed customized lens could fit the deformed cornea accurately and stabilize the sight of the patient.
Dr. Hongxin explained that a blueprint of a patient’s cornea can be used to fully customize the 3D printed spectacles to fit corneas of different shapes. This will correct the distortion of the eye-sight. “Normal corneas have a smooth and convex surface, while their [keratoconus patients]corneas are bumpy with many irregular concaves,” Dr Hongxin told Beijing News.
Inspired by NASA
Dr. Hongxin says the 3D printed spectacles for cornea patients were inspired by NASA’s adaptive optics technology (AO). NASA uses adaptive optics to improve its telescope’s image quality which is distorted by the Earth’s atmosphere. Computer-controlled deformable mirrors can correct the distorted image in real-time, producing finer images of extremely faint objects.
Researchers in Germany are using 3D printing to improve treatments for babies with cleft lips and palates.
In a study conducted at the Technical University of Munich (TUM), scientists have used 3D printing and semi-automated workflow to improve the process of nasoalveolar molding (NAM), a medical procedure used to help children with birth defects that affect their upper mouth/lip.
A typical NAM procedure uses a plastic plate to reform an infant’s lips, gums, or nose before undergoing surgery. While this allows for fewer, more effective surgeries, the technique requires constant new plates to be developed as the child grows. This leads to lengthy treatments found only in specialized locations.
The new TUM process, known as RapidNAM uses a semi-automated approach with automated detection of the alveolar ridge (upper and lower jaw ridges). This automatic detection means that NAM plate-molds are made faster and more effective than the traditional method where the ridge was given space for expansion. The molds are then digitized with a 3Shape brand 3D triangulation scanner.
Because the TUM process automatically detects the alveolar ridge, a graphical user interface (GUI) was created for any necessary edits.
TUM’s process is faster than the standard technique which required more manual design. Additionally, the use of 3D printing technology can produce molding plates at a faster, cheaper rate than the traditional method.
According to the TUM report, “RapidNAM overcomes previous limitations of conventional CAD/CAM-intraoral molding plates by its semi-automated workflow. The GUI creates a series of molding plates within a few minutes but still allows changes by the user. The resulting plates are as adaptable as conventional NAM-devices.”
3D printing and facial reconstruction
This isn’t the first time 3D printing has been used to help solves issues with cleft lips and palates. In 2015, Michigan doctors accurately managed to predict an unborn child’s cleft lip by translating MRI scan data into a 3D printed model. With this they were able to determine if the cleft lip would pose a danger to the child’s breathing.
Similarly, in 2017, doctors at Ninth People’s Hospital in Shanghai used 3D printing to reconstruct the face of a woman deformed due to a rare septic infection. The doctors used 3D printed models to guide the construction of the newly formed nose and mouth.
The TUM report concludes, “RapidNAM gives good clinical results and may bring nasoalveolar molding to a broader practice.”
In 2017 at the Karlsruhe Institute of Technology (KIT) in Germany, researchers succeeded in 3D printing, and erasing, microscopic structures 5 times the size of a human hair. An important step forward for high-resolution applications such as medical biopritning and microelectronics, the team has added a new level of sophistication to its research with multiple, erasable inks.
Micro 3D printing
Microfabrication at KIT is performed used a Photonic Professional GT two-photon lithography 3D printer from Nanoscribe Gmbh. The scale of the 3D micro structures produced in this particular study is below 50 μm – the average width of a human hair. To add a little more perspective, the longest chromosome in the human body is 10 μm long which is, incidentally, the same as the scale bar used on figures in the KIT study.
In total, the degradation of four different 3D printer inks is observed in this research: MSEA, ESEA, ISEA and PETA.
Wiping out the Eiffel Tower
After 3D printing each of the structures, the sample plate is submerged within chemical baths heated at 50 °C. In the first bath, the Eiffel Tower, made using MSEA, degrades within 20 minutes though the other three structures remain stable.
Next, in exposure to another chemical, an Aztec temple of ESEA took around 1 hour to degrade. Then, in a further test, ISEA was completely removed, again taking 1 hour.
Crucially, at the end of the three so-called “cleavage steps”, the Asian temple made from PETA remained as a reference structure.
In conclusion, “…we submit that the class of photoresists presented here hold large potential and will allow for the fabrication of a variety of complex and multifunctional 3D nano- and microstructures that are presently inaccessible using current state of the art photoresists and/or subtractive manufacturing methodologies.”
The team also believe that their inks could be used in other 3D printing technologies like SLA, and DLP.

Live Parts 1.5 includes a new seed cell feature, Connections, which automatically links fixed and forced surfaces of a 3D model, creating faster, more efficient 3D model outputs. Rather than working with predetermined shapes, Live Parts software produces parts “from the ground up” by growing seed cells, miniscule blocks that control the output of a CAD file.
“It’s a totally different approach to the way things are created because it’s not generating many different designs randomly,” explained Andy Roberts, Software Engineer at Desktop Metal and Creator of Live Parts,” instead it’s creating by developing a seed cell into an organism an is optimized for its environment.”
Like plants or animals, Roberts adds,
“Its constantly adapting to changes in the environment and changes in the forces then it creates lightweight parts that are strong and fatigue resistant.”
Generative design and 3D printing
At SOLIDWORKS WORLD 2018 Desktop Metal showed first version of its Live Parts software, which has been made in collaboration with Dassault Systèmes.
Still in development, Live Parts is described as “an experimental technology that applies morphogenetic principles and advanced simulation to auto-generate part designs in minutes.” This generative design platform was created to enable users to speedily realize the full potential of additive manufacturing with material and cost efficiency, as well as design flexibility.
Operating from a set of predetermined factors, such as size, purpose and weight, generative design allows its users to automatically create a variety of 3D model designs with minimal human input. The new Connections feature in Live Parts 1.5 gives its users the option to both manually or automatically join otherwise separated surfaces of a part, resulting in more novel design outputs.
Generative design versus traditional manufacturing
As an example use case of Live Parts, Desktop Metal engineers have created a lever, applying material only to support the areas where a pushing force is typically applied. By considering such real-world functionalities, the 3D printed lever can be produced with differing structures that tolerate stress in certain areas while remaining lightweight in others.
“We wanted to give the designer a tool that they could use to redesign their parts, or to design their parts from the ground up for additive manufacturing and for functionality,” said Jonah Myerberg, CTO at Desktop Metal.

Doctor swims English Channel to raise money for hospital 3D bioprinter
Andrew Wolf, a 63-year old professor and cardiologist, has completed a swim across the English Channel in an effort to raise money to establish a 3D printing facility for children with heart defects.
Wolf’s goal aimed to raise £20,000 in order to purchase a 3D bioprinter and enable medical model printing at the Bristol Children’s Hospital. According to Wolf, this technology could “transform” the lives of babies and their families, improving surgical planning of complicated procedures. The unit will also enable the team to explain and show in detail to parents and children what the problem is and how it can be fixed. Wolf believes that this cutting-edge technique would be one of the first facilities of its kind in the UK.
Before he set off on his 13 hour and 21-mile swim, Wolf said “The bio-fixing which we are working towards will allow children to have one-off operations with their own stem cells so they will not have to have repeated operations as they grow into adulthood.”
Cunicode’s new 3D printed art
Cunicode, a 3D printing art studio in Barcelona, Spain, has released a new collection of stoneware art called Permutation.
Each piece in the collection is composed of a random combination of nine basic units that are placed around a cylinder. These pieces were designed with Grasshopper 3D modeling software and 3D printed by on a PotterBot 3D printer.
One of the key selling points of these new pieces is that each one is unique and exists within an immense landscape of millions of possible different combinations. The 3D printed sculpture known as P16.4, contains over sixty-six quadrillion possible combinations.
Cunicode’s previous works includes other 3D printed artwork such as cups, busts, and figures designed after children’s drawings.
