Testing PTFE Tube for 3D Printing

testing ptfe tube for 3d printing

BEGIN ARTICLE PREVIEW:

Karl here. I’m back with a short article on some testing that I did on PTFE tube. When I received the Sovol SV02 3D printer it came with some baby blue replacement PTFE tube. It came preinstalled with the regular white stuff that most Bowden style printers come with. I have also been thinking about different ways to use the Retraction Calibration Tool I created. I recommend reading it first to get grounded on what this tool does before going further.I have always heard that Capricorn brand is the best so I purchased some on Amazon. I will test 3 kinds. Generic white, Baby blue Sovol, and Capricorn XS tubing. (Now that I am finding the links to add to the article I see that it is through the Sovol Amazon store. This is just a coincidence.)For the uninitiated, this little tube plays an important role in 3D printing. It provides a filament path from an extruder to the hotend. The theory behind quality is dimensional accuracy and tighter tolerances. Capricorn claims highly accurate tubing with a special blend that is very slippery. This picture captures tolerances very well.Why does this matter? 3D printers have to do …

Scientists 3D Printed a Soft, Tongue-Like Surface

scientists 3d printed a soft, tongue-like surface

BEGIN ARTICLE PREVIEW:

Scientists have fabricated synthetic soft surfaces, mimicking the texture of the tongue through 3D printing technologies – opening a wide variety of potential applications in food, nutrition, pharmaceutics, and other oral-related studies.
A research team led by scientists from the University of Leeds and the University of Edinburgh in the United Kingdom were able to replicate the complex surface design of a human tongue. They demonstrated in their study that the 3D printed synthetic silicone structure was able to imitate the topology, elasticity, and wettability – or its ability to retain liquids on its surface – of a human tongue.
These are the properties that affect the behavior of saliva or food as it touches the tongue, affecting the sensation in the mouth and the swallowing mechanism, as well as speech and quality of life.
3D Printing a Biomimetic Tongue
One of the urgent and significant applications of a biomimetic tongue, or a synthetic material that emulates the tongue, is in helping overcome the sensory disabilities caused by the global coronavirus pandemic. Sensory trials and consumer tests for experimental medication would see great progress, increasing development productivity for researchers and reducing the pharmaceuticals’ reliance on human trials.

Chinese scientists develop 3D printed drug-loaded nerve healing bandages – 3D Printing Industry

chinese scientists develop 3d printed drug-loaded nerve healing bandages – 3d printing industry

BEGIN ARTICLE PREVIEW:

Researchers from China’s Sichuan University and Xiamen University have developed 3D printed self-adhesive bandages that are capable of delivering nerve-healing drugs. 
The team’s fabricated gauze comprises two click-activated hydrogel layers and an inner-section which can be loaded with regenerative medicine. Once wrapped around the site of an injured nerve, the device releases the medication in a way that encourages the growth of glial cells in the Peripheral Nervous System (PNS). 
In the future, the scientists believe that their novel 3D printed dressing design, could assist doctors while they carry out widely-used nerve repair operations such as neurorrhaphy.

New treatments for nerve traumas 
It’s possible to injure a peripheral nerve in a variety of ways, ranging from sporting incidents to illnesses such as tumors, but they are almost always followed by a loss of sensory function in the affected area. Although the PNS has regenerative capabilities and is able to heal itself in certain situations, this is highly dependent on the size and scale of the injury. 
In some cases, neurorrhaphy (a specialized surgery) …

uk scientists 3d print lifelike biomimetic tongue with potential tasting capabilities – 3d printing industry

BEGIN ARTICLE PREVIEW:

Scientists from the University of Leeds and University of Edinburgh have 3D printed a synthetic tongue, which could be capable of sensing flavors in food. 
The researchers created their soft biomimetic device by 3D printing ‘papillae’ (or taste buds) similar to those found in the authentic organ, onto a silicone elastomer using a point process-based model. Utilizing their additive dorsum, which emulated the texture of the genuine article, the team aims to quantify the mechanical interactions between the human tongue and certain foods. 
“Recreating the surface of an average human tongue comes with unique architectural challenges,” said the study’s lead author Dr Efren Andablo-Reyes. “We aimed to replicate the mechanically relevant characteristics of the human tongue, in a surface that is easy to use in the lab to replicate oral processing conditions.”

BEGIN ARTICLE PREVIEW:

BOSTON, Oct. 27, 2020 /PRNewswire/ — The last decade has seen an explosion in 3D printing, among hobbyists and professional users alike. The ability to prototype – or even, increasingly, industrially produce – almost any component with just a CAD package and a 3D printer has transformed the manufacturing landscape. Although there are drawbacks to the process, including proportionate cost and scalability, recent improvements in 3D printing capabilities meant that pre-Covid-19, commentators predicted a bright future for this technology and the sector had been on a solid upward trajectory for around a decade.
However, the Covid-19 pandemic has wrought havoc with many sectors, including the automotive, aerospace and industrial markets that have adopted 3D printing most enthusiastically. This, and other factors, are impacting 3D printing just as it reaches maturity as a versatile manufacturing technique, and have stalled that pattern of growth. But for how long?
IDTechEx’s new report, “3D Printing and Additive Manufacturing 2020-2030: COVID Edition”, answers that and related questions, and takes a look into the next decade for 3D printing technologies.

While disaster has not yet befallen my humble family, there is no shortage of emergencies globally and the COVID-19 pandemic has demonstrated just how useful even desktop 3D printing can be during disaster situations. Provided with the opportunity to review an Ultimaker S3 3D printer and several unique filaments, I thought I’d explore the 3D printing of simple goods that might be useful during emergency situations to get an idea for just how useful a desktop 3D printer might be.
In addition to providing an overview of the subject, I’ve reviewed the Ultimaker S3 and spoken to Ultimaker about the use of desktop 3D printers in emergency and disaster scenarios. Perhaps the most exciting prospect for me when beginning this series was the creation of metal objects with a desktop system.
To explore the possibilities of making metal with a desktop 3D printer designed for plastic filaments, I reached out to the Virtual Foundry, which manufactures filament and pellets composed of metal particles within a thermoplastic binder. Once printed, the part can be sintered in a furnace, resulting in a dense metal part. In a subsequent article, we’ll get into more detail about the Virtual Foundry and …
