Weekend Project: Get Your Message Across with this 3D Printed LED Marquee Scroller
By Tyler Koslow

You can have the time, weather, news and more at your side at all times with this easy-to-build 3D printed LED marquee scroller created by Instructables user Qrome. 

In a world where infinite information is accessible at our fingertips, we’ve grown accustom to obtaining the latest news or data as soon as we wake up and unlock our smartphones. You can take things a step further by 3D printing your own LED marquee scroller, which was created by Instructables member and RC plane enthusiast Qrome.

The designer has made it possible to add a plethora of information to this LED marquee scroller, including a digital clock, local weather, news headlines, 3D printing progress via OctoPrint, the value of Bitcoin and even random and humorous advice. This project shows what you can accomplish with just a couple of electronic components and a 3D printer. Equipped with a 3D printed enclosure, you can get creative and mix different colors to go along with your personal preference.

Let’s take a look at what you need to build your own LED marquee scroller.

3D Printed LED Marquee Scroller: What you Need

There isn’t much you need to create this LED marquee scroller as far as components are concerned. Of course, you’ll need the STL files for the 3D printed case, which can be freely downloaded from Thingiverse. This project does require a bit of soldering, but Qrome lays out the step-by-step process very clearly. Aside from the 3D printed enclosure, here’s what else you need:

Wemos D1 Mini
Dot Matrix Module

In order to program the scroller with relevant information, you can follow along with the coding process included on the project’s Github.

3D Printed LED Marquee Scroller: Putting it Together

Starting off with the 3D printing process, Qrome suggests printing the two STL files (Base and Plate) with 20 percent infill, no supports required. The case is designed to snap-fit the Dot Matrix, and also includes a slot in the back panel for the Wemos D1 Mini. But before we start putting everything together, you’ll need to do some soldering first.

The Dot Matrix Module comes with the wires you can utilize during the soldering process. All you need to do is cut off the plugs and solder them directly to the pin locations on the LED Dot Matrix Display and to the Wemos D1 Mini. Here are the connections that need to be made:

CLK -> D5 (SCK)
CS -> D6
DIN -> D7 (MOSI)
VCC -> 5V+

Next, using Arduino IDE software, you’ll need to configure it to work with the Wemos board and USB port. There are a range of USB drivers, as well as packages and libraries, to download in order to program the marquee scroller. Qrome goes into detail on which to install on his Instructables post.

Once you’ve completed this, the final step is to configure the web interface.

The marquee scroller utilizes the Wemos board’s WiFiManager to become an AP Hotspot when the last network it was connected to can’t be found. You can connect to the WiFi manager with your phone and enter your WiFi connection information. After the device is connected to your WiFi network, the assigned IP address can be used to open a browser to the Web Interface, which is where everything can be configured there.

And that’s about all it takes to create your own marquee scroller. To learn more about this project, check out the Instructables post.

GE Files Patent to Improve 3D Printing Security with Blockchain Tech

GE Files Patent to Improve 3D Printing Security with Blockchain Tech
By Tyler Koslow

General Electric (GE) has recently filed a patent application that would allow them to use blockchain technology to validate and verify 3D printed objects on its supply chain. 

As both 3D printing and blockchain technology are adopted into our daily lives, there have been a number of instances where the two have converged to create groundbreaking applications. We’ve recently seen the development of the 3dP-Token by the manufacturing service provider, a cryptocurrency that provides customers with greater accessibility to 3D printed products at a lower cost.

Now, in yet another intriguing example of these two technologies intersecting, the industrial powerhouse General Electric (GE) has recently filed a patent application that would enable use of the blockchain to verify 3D printed parts in its supply chain. In this case, blockchain technology would be utilized to create a database that validates and verifies 3D files and the 3D printing process.

According to the filing, GE is planning to create a blockchain-based manufacturing history that would track and authenticate 3D printed objects. This would address one of the most glaring issues found with industrial additive manufacturing: the lack of verification and validation systems that are able to ensure the certification of 3D printed parts.

“It would therefore be desirable to provide systems and methods for implementing a historical data record of an additive manufacturing process with verification and validation capabilities that may be integrated into additive manufacturing devices,” GE states in the filing.

The U.S. Patent and Trademark Office (USPTO) released the application just last week. The patent application itself was filed by GE in December 2017.

GE Sees Blockchain Technology as an Answer to 3D Printing Security Problems

While GE is certainly the biggest name in industrial manufacturing to try and link blockchain technology with 3D printing security, they’re far from the first. Back in 2016, Cubichain Technologies released an application that uses secure blockchain networks to store encrypted data of 3D printable parts.

The increasing adoption of additive manufacturing technology has conjured up security concerns for industrial manufacturers, particularly with 3D printed models being compromised or changed. For instance, in GE’s patent filing, they explain that if a 3D printable replacement part is shared with users, the user on the receiving end of the model is unable to verify whether the part was produced using the correct build file and manufacturing process.

Therefore, the ability of blockchain to verify and authenticate data makes it the perfect safeguard to prevent a 3D file or printing process from being modified without authorization. And so, GE is planning to use this technology to verify their own parts on the supply chain, allowing them to track and certify every part that goes into production.

GE seems to be entering the blockchain space from a few different angles, having also joined the Blockchain in Transport Alliance (BiTA), which is a blockchain consortium that aims to use the technology to improve the cargo transport industry.

Traditional Knitwear and 3D Printing Combined to Create Clothing Inspired by Children’s Toys

Traditional Knitwear and 3D Printing Combined to Create Clothing Inspired by Children’s Toys
By Tyler Koslow

Designer and Royal College of Art graduate Lingxiao Luo is combining traditional knitting techniques and 3D printing to create garments that echo the playful style of children’s toys.  

As 3D printing becomes an increasingly popular tool in the world of fashion and art, the technology has been adapted to be compatible with other classic techniques. One shining example of this is 3D knitting, an automated knitting technique that is already being used by the furniture design giant IKEA. Sometimes fusing traditional techniques with 3D printing can lead to new innovative processes of their own kind.

One fashion designer, named Lingxiao Luo, is mixing traditional knitting methods with 3D printing to produce playful and vibrant garments. A graduate student from the prestigious London-based Royal College of Art, the designer’s latest work aims to replicate the vibe of children’s toys. The collection, which is called is called AddiToy, is produced via a method that involves 3D printing threads of plastic directly onto knitwear.

Luo had previously worked as a childrenswear designer, and that experience seems to have carried over in her ongoing experimentation with knitting and 3D printing. She believes that the AddiToy collection provides a new aesthetic to the fashion world, and also promotes the idea of zero-waste fabrication.

Lingxiao Luo 3D Prints Plastic Threads Directly Onto Knitwear

To create the colorful garments, Luo starts by selecting the type of yarn and deciding whether to weave it into a delicate or thick finish. The material she utilizes offers more texture and structure compared to traditional knitwear fabrics. Different 3D printed textures are added directly to the garment, where it is then either joined, felted or twisted directly onto the design.

The joining process is incredibly straightforward, using 3D printed patterns that are added to the fabric to attach two different knitted fabrics into a single piece. Felting, on the other hand, entails directly weaving 3D printed patterns into the knitted fabric. This method leads the fabric to become wet and felted, where it then shrinks to form the desired 3D design.

Lastly, the twisting technique involves printing flexible filament onto tightly-knitted elastic fabric, which enables the 3D printed threads to be twisted into the garments.

“In the future, AddiToy can provide technical service to design studios for using this technique and products into their collections,” Luo recently told Dezeen.

The designer has utilized her newly developed technique to create several pieces for her MA final collection for the Royal College of Art. These objects include a book of samples, garments, accessories and several perfume prototypes. Her garments were also featured in the recently held Royal College of Art MA Fashion show.

Australian Company is Constructing 3D Printed Homes From Hemp

Australian Company is Constructing 3D Printed Homes From Hemp
By Tyler Koslow

Australian hemp company Mirreco is developing a 3D printing process that utilizes hemp biomass as a material to manufacture building panels for houses. 

With the cannabis legalization movement spreading rapidly throughout many parts of the world, even the 3D printing industry has found ways to make use of this controversial plant. For instance, we’ve seen a handful of specialty hemp-based filaments that are both sustainable and fun to print with.

While hemp can be used for a wide range of applications–from clothing to food–the Australian company Mirreco is taking hemp to new heights. The Perth-based company is working on a process that would use hemp biomass to construct habitable residential homes. Having already developed a machine to process this multi-faceted plant material, removing the most useful components like fibers and seeds, the next step is to integrate additive manufacturing into the mix

By combining this hemp processing technique with 3D printing technology, this plant-based material will soon be used to manufacture building panels for homes. Mirreco is collaborating with the Australian architecture firm Arcforms to showcase the potential of hemp biomass in the construction sector.

Hemp-Based 3D Printed Houses are Coming to the Land Down Under

Aside from the cultural novelty of using hemp, this plant material also offers unique properties. In a recently released statement, Compared to traditional building materials, Mirreco claims that the 3D printed hemp-based panels are  “structurally sound, easy to produce, and provide superior thermal performance.”

“The floors, walls and roof will all be made using hemp biomass, and the windows will incorporate cutting-edge technology that allows light to pass through glass where it is converted into electricity,” the company states.

The hemp biomass material can be used to produce panels for residential and commercial buildings, and can be 3D printed into floors, walls and roofs. Arcforms will be designing the sustainable hemp homes, and have already sketched up the concept.

Mirreco has an overarching mission to curb the imminent consequences of global warming, and these carbon-neutral hemp panels fit into that vision. Hemp plants are capable of absorbing large amounts of carbon dioxide, which makes it an environmentally-friendly building material.

These hemp-based homes are certainly not the first example of 3D printing technology being used to build habitable structures. In fact, there are a number of 3D printed homes and other construction projects that have sprouted up across the world. However, Mirreco’s use of hemp plant biomass presents an evergreen path towards buildings that are incredibly sustainable and highly efficient.

Weekend Project: Start Saving with a 3D Printed Apple Coin Bank

Weekend Project: Start Saving with a 3D Printed Apple Coin Bank
By Tyler Koslow

Have some loose change lying around? Why not save it for a rainy day by 3D printing this gear motor-driven Apple Coin Bank designed by maker Greg Zumwalt. 

Saving money is a healthy financial habit that will keep your bank account growing, and even a few coins can go a long way. Many of us know that feeling of relief that comes about when we have some cash set aside, and developing these frugal habits will help us plan for the future.

Now, you can create a 3D printed Apple Bank to be your now coin-stashing companion. This model was designed by maker Greg Zumwalt, who was looking for a way to teach his grandchildren good money saving habits. The 3D printed coin bank is comprised of 20 different 3D printed parts, a single gear motor and two micro level switches. It operates back on the Hoeken mechanism,

The coin bank mechanics are based on the Hoeken mechanism. The design consists of 20 unique 3D printed parts and uses a single gear motor and two micro lever switches for operation. With large eyes and an appetite for currency, this Apple Coin Bank looks quite adorable and unintimidating. However, this project is difficult to print, and requires a lot of precision and careful planning (just like saving money does).

Let’s take a peek at what you need to build this 3D printed coin bank…

3D Printed Apple Coin Bank: What You Need & Putting it Together

As we mentioned, the Apple Coin Bank consists of 20 different 3D printed parts, all of which can be freely downloaded from Zumwalt’s Instructables post. Zumwalt warns that this project is no walk in the park, as the design include the threaded assembly, as well as small parts and confined spaces. But if you have your 3D printed well-tuned and some basic soldering skills, you should be able to create your own coin eating apple.

The designer suggests 3D printing all parts at .15mm layer height and 20% infill. Some parts require supports to print cleanly, so be sure to add those when necessary. Before you start assembling to Apple Coin Bank, Zumwalt also recommends that you test fit and trim, as well as file and sand all of the parts to ensure smooth movement for moving parts and a tight fit for the stationary surfaces.

Aside from the 3D printed parts, here’s what else you’ll need to assemble the Apple Coin Bank:

33x12mm 300RPM Metal Mini DC 6V Gearbox Gearwheel Motor Mini Reduce Speed Geared Electric Motor
4.5 VDC power supply
Coaxial panel mount power jack for a 9mm hole
2x Micro lever switches (CYT1073)
4x 2mm by 12mm screws, 2mm washers and 2mm nuts
2x rubber bands (70mm in length)

The build process begins with installing the motor into the 3D printed base and motor mount. After assembling the coin arm mechanism and completing the base, you’ll have to start soldering the wires together, which Zumwalt details on his Instructables post. After inserting the base into the 3D printed apple, the final step is to add the face to your print.

The step-by-step build process is lengthy and could be a bit arduous, so keep that in mind as you start constructing your own Apple Coin Bank. You can find the full assembly instructions and more on Instructables.

Weekend Project: Satisfy Your World Cup Fever with This 3D Printed Lithophane Lamp

Weekend Project: Satisfy Your World Cup Fever with This 3D Printed Lithophane Lamp
By Tyler Koslow

The FIFA World Cup is in full swing, and now you can 3D print your own lithophane lamp to light your favorite team’s path to victory! Check out this amazing 3D printed World Cup-themed lamp designed by the 3D printing company Voladd.  

With the 2018 FIFA World Cup currently taking place in Russia, people from every corner the world are getting faces painted and flags waving in support of their home country or favorite qualifying team. Depending on what time zone you live in, some World Cup games might start a bit too early or late for you, but most of us will turn on a lamp and watch through the night nonetheless.

Now you can light your path to victory with a World Cup-themed 3D printed lithophane lamp created by the 3D printing company Voladd. The model is based off of the event’s iconic trophy, which features a robed human holding the world up above their head. This model is a remix based on “World Cup” by Bekarion and “Spherical Lithophane – World Map 12cm remix” by Domi1988.

With a bit of post-processing, you can make this lamp look like the real World Cup trophy. If you want to keep the spirit of this international tournament alive with a 3D printed lithophane lamp, keep reading to find out what you need and how to build it!

World Cup Lithophane Lamp: What You Need & How to Build it

There are four different STL files that you’ll need to print to build this lamp: three parts for the base and the globe-shaped light source. These 3D printable models are freely available to download from Thingiverse. Voladd suggest printing these parts with 15 percent infill and supports when necessary.

Other than a 3D printer and the STL files, there are obviously a few other things you’ll need to make this lithophane lamp shine. Here’s what you need to build this project:

G9 220 – 240 V bulb
Bonding primer
Gold metallic spray paint

Now that you’ve got all of your supplies ready, it’s time to kick off the build process. The first step is to 3D print all of the parts for the base and world map. Next, take the electrical installation and insert it from the upper part of the base until it reaches the bottom of the 3D printed base. Once that’s situated, you can glue the three base parts together.

Once the glue is dried, cover the lamp cap with paper and apply filler to the model, sanding it down to provide a better surgace finish. After that, you’ll apply the bonding primer, followed by the gold metallic paint spray. In the example from Voladd, they also add a few green lines to make it resemble the original FIFA World Cup. For the globe, which is where the light source will emit from, the designers recommend only using a light coating of paint to ensure the light shines through properly.

And that about does it for the assembly process. Pretty easy, huh? Well, definitely easier than watching your favorite team playing in a close World Cup match… If you want to learn more about this project, you can find more information on Thingiverse!
