Disney Claims IP Infringement

These low-poly count figurines of Star Wars fame are being removed from Thingiverse

While 3D printing has encountered very few significant intellectual property infringement matters regarding printed models since its inception, it was inevitable that such a breezy path of unrestraint would run its course. Even more inevitable, the first 3D modeling infringement claims would, of course, come from Disney.

Disney, the adopted-parent company of the Star Wars franchise created by George Lucas and Lucasfilms, has demanded that Thingiverse, the STL file download site owned by Stratasys, remove a selection of Star Wars figurine models.

While there are a large number of Star Wars character models still available on Thingiverse and other STL file sites, including the ubiquitous Yoda heads, this move by Disney marks a turning point whereby the Dark Side of copyright law has begun to shred the unbridled freedom of 3D printrs to model and print their own creations.

As covered by All3DP, Disney’s attack on Thingiverse primarily seems focused on the detailed designs of Agustin Flowalistik from Argentina. Primarily, Disney’s claims of infringement have to do with three characters of Flowalistik’s modeling work: R2D2, C3PO, and Darth Vader figures. While these characters are now removed, Flowalistik’s work can still be downloaded in the form of an Imperial Stormtrooper.

2017 SEMA Show Event Report

Serenaded by a nonstop chorus of revving motors and squealing tires, the megalithic SEMA (Specialty Equipment Market Association) car show overtook Las Vegas the week of Oct. 31 through Nov. 3 with a vengence. Packed with new car accessories and manufacturing developments in automotives, SEMA remains the largest, most well-known car show in the world. Joined by Thai Editor Ratthakorn Niramitmahapanya, 3D Printr Magazine was on hand to witness the innovations 3D printing has made to the automotive industry.

Some cars were entirely handmade, like this 32-ish Dodge-ish creation by Phil Endicott of LizardSkin, a producer of sound control and heat insulation linings for cars

With more than 2,400 booths, and hundreds of thousands of attendees, and representing a $41.2 billion automotive aftermarket industry, the SEMA show is impossible to imagine for the uninitiated. The conference overtakes every single square inch of the massive Las Vegas Convention Center with thousands of cars, spilling out across numerous parking lots turned into test tracks and pop-up tent communities, where various television shows interview impressive arrays of race car drivers, custom car designers, and celebrity car buffs like Jay Leno. It’s a sprawl. If there were a large city purely devoted to all things that go vroom and move fast, SEMA is what it would look like and Leno would likely be mayor.

The takeaway of our experience of the SEMA show this year was customize, customize, customize. Consumers don’t want the same old thing anyone else can buy. They want a signature brand, a vehicular statement worthy of respect. Take the “3D-Printed Hellcat Project,” a 2016 Dodge Challenger SRT customized with 3D-printed modifications and presented at the show by Airwolf 3D.

2017 SEMA Show Event Report

The brainchild of Airwolf 3D‘s president Erick Wolf and fashioned by his innovative team in Fountain Valley, California, the “World’s Most 3D-Printed Hellcat” is a customized car with 3D-printed features that make it a one-of-a-kind show piece highlighting what 3D-printed customization can do for the aftermarket industry. In addition to a number of interior modifications like customized rear speaker covers, safety handles, coat hooks, and a redesigned center shift console, Airwolf 3D also 3D-printed a full-size spoiler to show off what the company often heralds as its claim to fame: large-volume desktop 3D-printers capable of printing in high-temperature engineering grade materials like ABS and polycarbonate.

The spoiler was printed in four parts on the Axiom 20, the largest desktop 3D printer in its class with a 12x12x20-inch build volume. To drive home the point that 3D printing represents true cost savings for an automotive shop, all custom parts on the car were printed for less than $250.

“This is the first time real, functional parts can be made in large format for minimal cost,” explained Wolf. “We 3D-printed a full-size spoiler and functional engine vents in ABS. That’s obviously something you can’t do with PLA, which can’t be used near heat — PLA also can’t be sanded or drilled to produce these parts.”

There’s a history to the 3D-printed Hellcat and its inception. Wolf got involved in 3D printing because of automotive design. Back in 2011, while still working as a patent trial attorney in Los Angeles, Wolf spent his free time pursuing his true passion: cars.

As a lifelong car lover with a degree in mechanical engineering and over 20 years of hands-on automotive experience, Wolf had a vision of the car he always wanted to design. Frustrated with using everything from clay and wood to build his prototype, Erick decided to try an inexpensive 3D printer. As the story goes, the printer failed miserably and Wolf decided to build his own. Wolf and his wife, Eva, eventually listed the 3D printer on Craigslist and got responses in minutes. The pair continued to sell their 3D-printers on Craigslist and, realizing there was a true demand for the machines, the two decided to start their own company and Airwolf 3D was born.

3D Magic Mike’s obsessively diligent CAD work resulting in printed parts

3D Printr Magazine had sought out Vibrant at SEMA because we had received news that they were working with 3D Magic Mike (aka Mike O’Brien from Roadstershop) and his amazing 3D CAD work. In this case, Magic Mike had recently designed an entire car, with every separate part, in 3D model. In our search for Magic Mike and Vibrant, we caught up with Thornton at the SEMA booth and were able to learn more about how Vibrant was incorporating 3D printing into their work stream.

One of the facets of 3D printing Thornton was avid about was the printing of jigs for inspecting production parts. His ability to quickly iterate a soft-surface jig that won’t scratch finished surfaces or a negative of a part to test tolerances has made their production go fluidly.

“We’ve been to SEMA more than ten years now and in the last four to five years we’ve seen more and more people understand the benefits of 3D printing, and how it can benefit the development of new parts” said Thornton, who also commented they use Solidworks for their design work. They have also recently added the flow simulation suite and are extremely happy with its performance. For scanning, they rely on an Artec Eva with translation to Solidworks through a DezignWorks add in9.

Thornton has been pursuing this career path since 1999, where his craftsman skills eventually led him to laying welds in an F1 shop midway in his career. In speaking with Thornton, one becomes engaged in the broad range of expertise he brings to the Toronto-based Vibrant’s design and engineering team. When asked about his educational background, Thornton admits he is essentially self-taught through a hands-on background with everything he does.

“I attended a few years of design in college but found it wasn’t teaching me anything about hands-on automotive fabrication and parts development. I found quickly this is where my true interest lied. I could have gone back to school for engineering, but I was too eager to start learning real life skills and applying them. Looking back on it, now working with a few engineers, I can definitely see the difference in my education versus theirs. My learning curve and success has not suffered though, from not pursuing an engineering degree. I found being hands-on early in my career was the best way to know how to design and execute any sort of part or product,” said Thornton, a senior technical member of Vibrant. The company also employs a team of select fabricators and engineers whose own principled manner of problem-solving complement Thornton’s approach.

It was also clear from the ever-present crowd at Vibrant’s booth that many other people knew about Vibrant’s great product line and their accomplishments in private label manufacturing, but that is the draw and importance of being a part of SEMA. That these companies seek to promote themselves here speaks well of their outreach and forward-looking thinking. How 3D printing will change the auto industry depends on what comes of this show and future ones.

Stereolithography Turns 30

Posted by Fred Kaplan On November - 7 - 2017Comments Off on Stereolithography Turns 30

Stereolithography—Staying relevant in the 21st Century

By Jim Reitz

Turning 30 invites a time of reflection. The landscape of additive manufacturing has changed dramatically since the 1988 commercialization of stereolithography (SL) as the first viable 3 D printing technology. In fact, the terms “3D printing” and “additive manufacturing” only entered the popular vernacular in recent years.

The scope of additive manufacturing has changed dramatically in recent years. Technologies encompassing thermoset and thermoplastic materials, as well as metal, have proliferated.  The 2017 Wohlers Report lists 96 different AM equipment suppliers across a broad range of technologies. Advances in equipment, software, and material have been substantial since the early days of SL, concurrent with increasing computer power and growth in the 3D CAD installed base. Competition within the early technology supply base has increased as patents expire and new players come to the international market. So, what’s in store for this young technological grandfather?

Stereolithography (SL) like all additive manufacturing processes provides a means to translate 3D computer models into a physical shape without machining. Material performance characteristics combine with 3 D printing methodology to shape application capabilities. Today, the inherent characteristics of 355 nm laser based SL technology characteristics leverage ever-expanding material capabilities to facilitate maturation into one of the widest used and highest utility AM processes. The term SLA, a registered trademark of 3D Systems, is often used by some to encompass a variety of 3D printing processes that fall within the ASTM grouping of AM processes as “Vat Polymerization.”

Stereolithography in this discussion will be focused on “industrial SL “, as the original technology has evolved and is differentiated from all other vat polymerization processes by:

  • Platform sizes ranging from 250 mm (9.5 in.) square to over 800 mm (31.5 in.) square.
  • Ultraviolet laser (355 nanometer wavelength) light source
  • Materials specifically formulated for 355 nm UV including clear, pigmented and composite systems
  • Imaging from above (build platform travels downward) 
    UnionTech High Resolution Part

    Metal Plated High Accuracy Sample Part Demonstrating Resolution and Precision of 355 nm Stereolithography

    The use of a laser to instantly cure a photopolymer with a UV laser with a nominal spot size less than 0.2mm provides one of the highest combinations of accuracy and resolution of any AM process, especially considering the range of part sizes the process is capable of. Today’s 355nm SL materials can produce parts that have excellent dimensional consistency and surface aesthetics ranging from transparent to a variety of colors resembling typical injection molded parts.  These materials have overcome robustness and aging issues encountered in earlier generations, allowing for parts manufacture with a broad range of mechanical properties allowing functional applications in prototyping, patterns, and beyond.

    Aerosport is successfully producing highly accurate parts that need very little finishing at the end of the process in the UnionTech™ RS Pro600, a recent entry to international markets.

    Additive Manufacturing (AM) processes utilizing thermoplastic materials are often cited for robust mechanical properties. Current generation SL materials can be selected to significantly overlap the performance range of many of the commonly used thermoplastics in other AM processes while retaining all the accuracy and aesthetic benefits of the SL process.

    Stereolithography is often typecast as a prototyping process sometimes based on an outdated understanding of material capabilities. The attributes of 355nm SL equipment in combination with the latest generation of photopolymers enables applications that extend prototyping capabilities as well end uses.  Significant opportunities in patterns for secondary forming operations ranging from large scale mass customization (dental aligners), low volume urethane part production, tooling for low volume injection molding, and metal clad composites are now being actively pursued. These applications are practical examples of how innovation can be attained via integration of SL with other conventional processes.

    Innovation via Technology Integration 

    The 3D printing process is often positioned as a disruptive technology but it is better thought of as an enabling technology.

    In the late 1990’s, the founders of Align Technology imagined a different business model for correcting the alignment of teeth with a series of retainers. Today, this application is possibly the highest volume application example of mass customization. Converting the CAD images of individual patients to patterns used to thermoform the final aligners enabled what most would call a disruptive business model.

    SL patterns for a secondary thermoforming process remains the dominant technology of this application today, based on the rapid processing times on large format machines optimized for this single application of mass customization.

    Investment casting, one of the oldest known metal forming processes, has used the SL process for over twenty years. The ability to manufacture hollow smooth walled patterns for use in a foundry process that coats the pattern with ceramic, then fully burns out the pattern in preparation for molten metals to be cast in the hollow form. While molded wax patterns dominant most high-volume applications, SL eliminates tooling costs for lower volume casting but also facilitates sizes and part features not readily obtained in a molded pattern process. The latest generation of SL photopolymers for this application have excellent dimensional consistency and contain no heavy metals found commonly in 355nm photopolymers. This combination ensures accurate patterns as well as minimal ash after burnout that can cause casting defects.

    Investment Casting Pattern Manufactured With Somos® Element

    Similar hollow part methodologies used for investment casting can be applied to large parts, creating “lightweight” parts with tailored mechanical properties and reduced weight (less material cost). Materialise, a global AM software company based in Belgium, has developed multiple software options for hollowing and reinforcing lightweight structures. This development has facilitated the cost-effective manufacture point-of purchase displays, architectural model, and other art applications.

    The ability to manufacture full density highly-accurate patterns also facilitates another well- established molding process known as urethane molding, RTV or silicone molding. After careful secondary finishing, the pattern is embedded in a silicone rubber casing that becomes a 2-part mold for the casting of urethanes. Polyurethane materials can be formulated to achieve properties consistent with levels of performance from injection molded thermoplastics. The silicone tool can be used for low volume series when either multiple prototypes or low volume production is required. Many service bureaus have developed specialized methodology for supporting regular low volume part production capabilities that can both shorten supply chains as well as allow for iterative improvements as a low volume design ages.

    Creation of injection molding tooling has been an area of development interest since the earliest days of SL. The principal impediments to this potentially high-volume application for prototype and bridge parts include strength and temperature resistance of the 3D printed tool, predictability of tool life (durability), compatibility with a large range of injection molding materials including glass filled systems (abrasion resistance) . Also, high speed CNC machining of soft metal (typically aluminum) tools , a parallel technology , provides the potential of short lead times and predictable tool life. In just the last 2 years, the convergence of SL part build accuracy, material capability (heavily silica filled photopolymers and business models that combine SL tool building expertise with injection molding know-how has led to increased use of SL tooling.  Successful integrators of SL 3D printing and injection molding typically recognize that the goal is an injection molded prototype. Injection molders lacking an internal CNC machining operation can readily print mold sets for prototype production in actual end-use designated thermoplastics. This avoids the difficulties that can arrive with a pass-the –baton methodology that marked early efforts to equip service providers with injection molding tooling know-how.

    Dr. Sean Wise of RePliForm (left) and colleague Rick Dunlap are holding new electroplated stereolithography parts including a copper plated wave guide and nickel coated flexible mesh at the 2017 AMUG (Additive Manufacturing Users Group) conference in 2017.

    Like investment casting, electroplating of a substrate material to improve physical or mechanical properties is well known. Dr. Sean Wise of RePliForm, Inc has actively optimized electroplating techniques for 3D printed parts using copper and structural nickel since the year 2000. All 3D printed materials can be electroplated to improve strength, wear resistance, EMI/RFI shielding, flammability resistance, and aesthetics. Photopolymer based printers; however, offer smooth, non-porous surfaces that plate readily with basic parts preparation.  355 production SL machines and state of the art materials combine to provide the largest range of part size and substrate options. The same highly filled silica photopolymers used for injection molding tools can create extremely thin (0.010 to 0.040 in) substrates for a Nickel/copper/SL composite with mechanical properties approaching die cast nickel. This level of mechanical performance creates a significant bridge of opportunity between the gap of polymer AM and direct AM metal. Aside from mechanical properties, the design flexibility of SL combined with a copper coating can create a cost-effective wave guide or “antennae configuration.” There are other parts currently in production where the structural nickel creates a renewable wear surface.

    The stereolithography process is successfully being used to create tooling for short runs.

    Turning 30 does bring changes. 355 nm SL, inclusive of equipment, materials , and software ;has matured into one of the most widely used 3 D printing technologies not only for prototyping but for use in end-use production processes. The trajectory of current developments and utilization in a broad range of direct and  indirect manufacturing techniques, as well new prototyping capabilities bodes well for a long life.

The Daily 3D Detail: Advances in Solar Greenhouses

Posted by Editor On November - 5 - 2017Comments Off on The Daily 3D Detail: Advances in Solar Greenhouses

While not yet in the immediate purview of 3D printing, solar technology advances are an item of immense importance to nearly all industries. This story is no exception.

Researchers at the University of California Santa Cruz have published their findings on solar greenhouses wherein plants do well in energy-producing buildings.

According to the report, “Electricity-generating solar greenhouses are outfitted with transparent roof panels embedded with magenta luminescent dye that absorbs light and transfers energy to narrow photovoltaic strips, where electricity is produced. A new study shows that this novel technology, which has the potential to take greenhouses offline, didn’t interfere with plant growth or production.”

3D Printr Magazine Now in Thai

Pictured is the 3D scan and print made for the recent Royal Cremation of His Majesty King Bhumibol Adulyadej (King Rama 9).

Following last week’s announcement of our publication becoming available for Portuguese readers comes this week’s news that 3D Printr Magazine is now publishing in Thai.

The Thai language boasts 56 million speakers, with roughly 14 million more able to understand and communicate with Thai speakers through their similar languages. The most notable of these is Laotian from the neighboring country of Laos.

Ratthakorn Niramitmahapanya is our Thai editor and comes from Chang Mai University in Northern Thailand where he earned a Bachelor’s degree in mechanical engineering.

“The need for 3D printing skills in Thailand is big because manufacturing is big,” said Ratthakorn, who is skilled in Solidworks and the Onshape platform for CAD modeling yet prefers Dassault Systèmes’ CATIA V5, which he considers one of the best in 3D-modeling software.

With a continuing interest in automotives, Ratthakorn, who previously worked with tire giant Michelin in the position of garniture engineer, is hoping 3D Printr Magazine will be able to reach many more gear heads like himself. His belief is that technology never stops growing, and the importance of 3D printing in the manufacturing process cannot be overestimated.

We welcome Ratthakorn’s contributions and efforts to reach out to the inventive and industrious people of Thailand.

3D Printr Magazine Now in Portuguese

Posted by Editor On October - 25 - 2017Comments Off on 3D Printr Magazine Now in Portuguese

3D Printr Magazine Now in Portuguese3D Printr Magazine is pleased to announce the launch of the Portuguese Edition of our publication at 3DPrintrMagazine.com.br.

Portuguese is generally regarded as the sixth most natively spoken language in the world, the third-most spoken European language in the world in terms of native speakers, and a major language of the Southern Hemisphere. There are an estimated 260 million speakers of Portuguese.

Taila Rodrigues, managing Portuguese editor for 3D Printr Magazine grew up in a small town surrounded by rural areas in the state of Parana, in the south of Brazil. She received her Bachelor’s degree in Computer Information Systems from Ourinhos Integrated Faculties (FIO) in Sao Paulo. In Paraná, she served in the Office of Social Services as director of the Municipal Department of Psycho-Social Assistance, helping people in situations of social vulnerability.

She moved to Los Angeles, California, in search of a personal development in technological skills which led her to 3D printing. While taking classes at Santa Monica College Continuing Ed, she was introduced to the capabilities of the new medium and was captivated. She enrolled in their 3D printing classes and built her first 3D printer for $200.

“A lot of companies want to know about this in Brazil and I want to make that happen,” said Rodrigues, whose belief is that technology can be accessible for people worldwide.

The Daily 3D Detail: New Algorithm Speeds Up FDM 3D Printing

Posted by Editor On October - 24 - 2017Comments Off on The Daily 3D Detail: New Algorithm Speeds Up FDM 3D Printing

University of Michigan’s Smart and Sustainable Automation Research Laboratory (S2A Lab) reports they written a new algorithm capable that can speed up an FDM 3D printer to operate up to ten times the speed.

Researchers 3D-printed a 37.23mm-wide scale-model of the U.S. Capitol Building in three hours and six minutes, achieving an acceleration rate of 10 m/s2.

An ordinary 3D printer accelerated to this point without the new algorithm would result in a failed print because of shifting layers from vibrations of the stepper motors.

Molong Duan and Deokkyun Yoon, researchers of the Michigan study, under the direction of Professor Chinedum Okwudire, said, “The motion of the printer’s build platform is along the x -axis, while its print head moves along the y – and z- axes.

“All three axes of the printer are controlled by stepper motors, but the focus of this study is on controlling its x – and y- axis motions which generate significant vibration, due to the printer’s flexible structure, as its print head and build platform move.”

In an industry raft with acronyms, there’s one more to add to the list: LPFBS (limited-preview filtered B-spline). This is the method devised by Duan, Yoon, and Okwudire addressed by the algorithm. By using an online feedback loop, a realtime check system is conducted that constantly rights the printer head for an accurate position.

The value of the algorithm could be considerable for 3D printing, as it can be easily implemented in spooler software, applicable to all levels of desktop 3D printers, and much less costly than sensors and hardware options.

The report was published in the scientific journal Mechatronics and available at ScienceDirect.com. For more on the story, visit 3DPrintingIndustry.com.
