Coasty Drink Coaster Laser Cutter

Customized laser 3D printed coasters are a thing now. Design your own with The Coaster Toasty to liven up your parties at home.

So New Year’s is coming up – who wants to serve drinks on normal, boring coasters?

For those DIY types that prefer something a bit more interesting, Bart Dring, designer of the 3D printed customized drinks coaster maker Coasty, has just updated his latest design.

Coasty version 1.2 is a small custom-made laser cutter you can use to impress your guests. In just a few seconds, you can print your own design onto your 3D printed coasters.

So, you’re probably wondering, why the update?

“I was not happy with the coaster homing switch used on the first version. While it never failed, it did not appear to be very robust and it caused some drag on the coaster. I changed to a IR LED and photodiode. When the light from the LED hits the photodiode, it conducts to the +5V. When the coaster blocks the light, it is pulled down to ground,” Dring explains.

OK, so maybe that sounds like something you personally wouldn’t need around the home. But you can still appreciate the tremendous detail that has gone into Coasty.

The hardware of the machine is largely 3D printed, apart from the motor, rod, and mechanical components. This lends it a more professional look, which would be difficult to achieve otherwise.

Coasty resembles a commercial product and uses a pulpboard coaster to cut the designs. Without opening up the machine, you can simply feed a coaster into the slot and the laser cuts your requested design.

Check out the video below to see a demo.

What are the new features of the new Coasty 1.2 version?

The Coasty Toaster is small and portable with a convenient new transparent window. Plus, you get some additional hardware features such as stepper drivers, a Bluetooth radio as well as laser power supply make for an even neater design.

Now, with the latest update, it includes a smaller traction roller, which moves the beam closer to the rubber contact points. This offers a range of advantages including enhanced resolution and torque.

Additionally, Dring has minimized the size of the chassis by 16mm and added a fan cover to the back of the design. So, this also enables you to add carbon filter cloth to the back to get rid of the odor originating from the printing process.

So if you’re a DIY enthusiast who wants to create unique coasters for serving your guests, Coasty could help you get ready for your New Year’s party in style.

Researchers Develop 3D Printing Technique for Precise Deposition of Energetic Materials

Researchers Develop 3D Printing Technique for Precise Deposition of Energetic Materials
By Anne Freier

Researchers from Purdue University have developed an inkjet-inspired 3D printing technique that offers a more precise and safer way to deposit energetic materials.

Energetic materials within micromechanics is a growing field, particularly when it comes to applications within micro-propulsion systems. Energetic materials require careful handling and the precise deposition of such materials. However, traditional methods such as electrophoresis have often failed in controlling the spatial properties and volume of the deposited material.

Now, a team of researchers at Purdue University have developed a new 3D printing technique that deposits micro-scale amounts of energetic materials. Similar to an inkjet printer, droplets of ink are combined to produce the material, select nanomaterials were deposited using a piezoelectric inkjet printer.

According to Allison Murray, a PhD in Mechanical Engineering, who developed the printer, the system fuses energetic materials together with additive manufacturing. Devices such as airbags tend to incorporate small amounts of energetic materials such as propellants. However, smaller devices generally require these materials on the micro-scale.

Researchers Embed Energetic Materials into Inkjet 3D Printing Process

Jeff Rhoads, Professor of Mechanical Engineering and a principal investigator on the project, explains:

“Our solution is to combine two components as we’re printing them. We can have a fuel and an oxidizer in two separate suspensions, which are largely inert. Then with this custom inkjet printer, we can deposit the two in a specific overlapping pattern, combining them on a substrate to form nanothermite.”

He adds that getting the correct droplet volume and pattern was one of the core challenges on the project. Now, the nozzle can move within 0.1 micron precision – a thousandth the width of the human hair.

Such two-part reactive printing allows for the mixture and storage of energetic materials. This renders the process safer and also adds to the overall shelf stability. For the future, the team says that a technique for bulk characterization of samples could be explored. In addition, the size of the deposits made could be further adjusted.

Now published in the Journal of Applied Physics, the proof of concept work was carried out by 10 researchers and four faculty members from different departments at Purdue.

“It’s a defining feature of Purdue that professors from such different backgrounds can work together on a project like this,” Rhoads concludes. “We can combine all of our experiences to collaborate on technologies that weren’t previously realizable.”

Doctor Drives to Sierra Leone with Ultimaker 3D Printer to Make Prosthetics for Children

Doctor Drives to Sierra Leone with Ultimaker 3D Printer to Make Prosthetics for Children
By Hanna Watkin

Doctor Lars Brouwers is driving from the Netherlands to Sierra Leone with an Ultimaker 3D printer to teach locals how to print limb prosthetics for children. 

With a friend by his side, Brouwers set off on the ultimate road trip. The Dutch doctor is currently en route to the Innovate Salone program in Freetown, Sierra Leone.

His mission? To help local children with missing limbs by 3D printing prosthetics for them.

“It is important that developments in technology and innovation are also introduced in the third world. By transferring our knowledge and the 3D printer, we want to contribute to healthcare. Otherwise, the differences with the prosperous countries will only increase,” Brouwers explains.

In addition to doing his bit to bridge the gap between rich and poor, Brouwers believes that this technology will hugely benefit more children.

In Sierra Leone, some children are born without limbs due to birth defects or sadly lose them to war.

Now, with the Ultimaker 3D printer, it’s possible to make a prosthetic hand in just one day. The devices are even able to grip things thanks to fishing wire and hinges.

The trip is now underway and Brouwers, along with a friend, who already lives and works in the country as a doctor, will arrive in the capital of Sierra Leone in three weeks.

All Systems Go Once Brouwers Reachers Freetown

In order to help Brouwers help the local project, Ultimaker sent him a 3D printer worth about $3,000 (€2,500) for free.

The Ultimaker 3D printer will also arrive fully equipped with software and spare parts. Plus, Brouwers has already arranged technical help if anything goes wrong.

“Technical problems are often easy to remotely remedy, for example via the app. And if it is very difficult, I can call on a befriended colleague in the Radboud UMC‘s 3D Lab,” he explains.

Innovate Salone is a program created by the Global Minimum organization. Hopefully, 3D printing will be able to greatly benefit the program.

“I want to show that 3D printing works cost-effectively compared to normal care. I have been working on that for two years,” Brouwers adds.

This is only a shortstop as the doctor has a very busy schedule as he continues his doctoral research and will begin training as a surgeon in Nijmegen, Netherlands in January. We wish him the best of luck!

MINI Launches 3D Printing Service to Offer Customized Car Accessories

MINI Launches 3D Printing Service to Offer Customized Car Accessories
By Tyler Koslow

The automotive company MINI has launched MINI Yours Customised, a new 3D printing service that will allow customers to design custom interior and exterior trim pieces and have them 3D printed for their car. 

Many people believe that cars, much like dogs, tend to reflect the personality of the owner. The bubbly and bug-eyed MINI is certainly no exception to this rule.

This past week, the British automotive marque MINI launched MINI Yours Customised, a 3D printing service that will allow customers to design their own interior and exterior trim pieces and have them 3D printed.

There are a wide range of components to modify and choose from, including the side scuttles for the exterior turn signals, the passenger-side dash trim, LED aluminum door sills, and the LED door projector. MINI is utilizing 3D printing and laser cutting technology within its production facilities in Germany to deliver these unique, customized parts to customers.

The 3D printing service will allow customers to select, design, or upgrade parts from the new Online Shop. These parts take just a few weeks to be manufactured before they’re ready for the road.

“MINI Yours Customised” Puts Power of Customization into the Driver’s Hand

MINI Yours Customised offers a user-friendly customization tool that enables every customer to use their own creativity. Each design can be selected and configured before being sent off to the facility for production. For example, the customer can choose different colors, surface finishes, and patterns for their side scuttles and trims.

With the help of MINI’s parent company, BMW Group, the automotive marque has gotten its hands on some impressive 3D printing technology. This stems for various partnerships between BMW and the likes of Hewlett-Packard Inc., Carbon, and EOS GmbH. Laser cutting is also used to perform tasks such as etching the customer’s name into the door sill.

The new service from MINI also aims to develop a community of creative users who are sharing their designs on social media and inspiring others.

“MINI is committed to digitalisation and innovative production procedures for realising individual customer wishes. Alongside the global web shop, a completely new distribution chain has been installed for direct sales to the customer. Equally, the 3D printing procedure has been specially tailored to the production of individual products in large numbers for the MINI Yours Customised package,” BMW Group stated.

Although the new 3D printing service is major news for the automotive industry, MINI’s latest use of the technology isn’t exactly shocking. Just last week, BMW released a number of 3D printable Christmas ornaments, while also sharing the different ways that additive manufacturing his pushed its own iconic automotive brand forward.
