Why In office 3D Printed Aligners Is More Affordable&Effective For Everyone?

 ArchForm, a clear aligner treatment planning software company, announced that it has opened a 3D printing factory for orthodontists aligners on demand On October 15, 2020 and decided to go public in December.

ArchForm produces aligner for half the price of other companies to rival industry leaders like Invisalign, Byte, Candid and SmileDirectClub. According to the company, ArchForm’s aligners are manufactured by robotic precision engineering with a multi-layer plastic material , and will can be delivered to a specific orthodontist within 10 to 14 days.

Invisalign reduces some of the costs of metal braces treatment.However,most of the orthodontists’ profit margins are controlled by parent company Align.They currently pays about $1,700 per patient to Invisalign, and other clear aligner vendors following the same regime. ArchForm is changing this pricing structure.With ArchForm, the cost for orthodontists to print a moderate-to-severe case in-office is reduced to $542, and each patient will be charged only $14.

The production of dental aligners requires the use of professional 3D software to design a stepwise series of 30 to 40 aligner models that can adjust the patient’s teeth based on the scan data.The models are then 3D-printed and the actual aligners are produced by thermoforming biocompatible plastic over the models. With ArchForm’s software,Many orthodontist offices that already have 3D printers can save money and be allowed to plan cases faster with automatic one-click features.

For practices that do not plan to invest in 3D printers, ArchForm’s new plant is ideal for outsourcing the aligner designs.Using a higher-resolution 3D printer, three-layer plastic material, and a robot that is more comfortably precise than manual trimming, ArchForm claims to manufature more accurately shaped aligners with less visible layer lines.

Ideally, using ArchForm can help orthodontists to take digital scans at patient’s first appointment, 3D print the day’s aligners in their office labs, and then outsource the remaining treatment to ArchForm’s aligners. By reducing the waiting time from six weeks to four weeks, orthodontist can offer better service as a result.

A Self-healing 3D Printed Plastic Webs Could Save Cracked Phone Screen

 There are few things more frustrating than getting a little tiny crack or even a big crack in your smartphone screen. That’s really annoying. My friend recently dropped his phone with a screen protector again. He’ve broken that screen about four times over the period of the last 2 or 3 months. Ah, If we could only get a self-healing phone screen! 

Thanks to  the efforts of  the Professors Frédérick Gosselin and Daniel Therriault, Now we can do more than just imagine.

These two researchers have much success in producing an ultra-strong polymer fibre and  the inspiration came from the structure of spider silk.They claimed it was made of the unique molecular structure of the proteinacious material,which can absorb up to 96 percent of impact energy before breaking. This helps to creat the unbreakable plastic coverings for various kinds of delicate technology devices.

Other than this bionic design,the researchers adopted the technology of 3D printing. Heat the polycarbonate first to make it become viscous like honey.Then Professor Gosselin’s team made use of this property to print a series of fibres less than 2mm thick. They repeated the process quickly, “weaving” a new series of fibers in a vertical arrangement to achieve the entire network solidification.

It’s worth noting that as the 3D printer slowly extruded polycarbonate to form a fiber, the molten plastic finally formed a series of hardened loops that give the fiber extra strength as sacrificial links.

When the impact happened,  these fibers actively withstood the damage caused by the impact energy, sacrificing the ego in the similar way that spider silk proteins do to protect the integrity of the whole.

Looking forward , the technology is expected to help electronic devices achieve the desired effect of impact protection.We might also be able to make a new type of bullet-proof glass, or a protective coating for aircraft engines.

The Smallest 3D-Printed Boat You’ve Ever Seen

 You must be surprised When you see the iPhone 12 mini for the first time , which is literally tiny by contemporary standards.In the real world, , we may think of a small thing as nothing more than a bean or a grain of sand, or even a strand of hair.But you know what, scientists used a 3D printer to create a 3D Benchy boat, the length of which is 1/3 the thickness of a hair, 6 times larger than a bacterial cell.

Researchers used a scanning electron microscope to photograph the ship for purpose of showing its open cabin, a chimney, and even a small porthole. What’s most impressive is that  the entire model is very tiny, which means it’s even smaller than a statuet created by artist Jonty Hurwitz in 2014 as a potential design for creating a little drug delivery vehicle.

The researchers conducted investigations into small particles called microswimmers that can move through fluids, and be followed by a microscope.They created many structures , including a spiky sphere, a spiral, a trimer,a 3D Benchy boat and so on. Research shows that particles created in a helix shape can go around and be efficient. 

“When it moves forward, often it needs to rotate, and that helps, for example, to speed it up.”Daniela Kraft said, a physicist at the Dutch university,adding that the small particle that goes to a particular part of the body to deliver drugs has to propel itself and may have to deal with the complex environment in human’s body.
