The Mannequin Challenge

The Greneker office strikes me as a place you wouldn’t want to be stuck wandering at night, what with the bodies lurking around each corner. I scheduled my visit for early afternoon.

Greneker is a mannequin manufacturer based in Los Angeles, California. They’ve worked to stay cutting-edge in their industry since they started in 1934, always keeping pace with the latest groundbreaking materials and manufacturing methods, like moving from plaster to fiberglass around World War II.

They’re proving that even an entrenched player in the game isn’t too old to learn new tricks: their latest foray is into the worlds of digital and 3D printing.

Steve Beckman is President & COO at Greneker, and he’s been a part of the evolution of the company over the last 2+ decades as they’ve set themselves apart in their industry.

When I started with this business, we would get together as a group, we would look at the trends in the marketplace, and we would develop a line based on what we saw happening in the marketplace at that time.” It was a big gamble – the process was both costly and time-intensive – but that was just business as usual for them. “That was done with clay sculpting, so we would start with armatures and clay, go through the process ourselves, create an entire line of mannequins, and really just kind of rolled the dice and hope that it would sell to that market.”

Whereas they began by working independently from apparel manufacturers, Greneker found themselves doing more and more custom work for specific clients. They found their niches in the athletic wear and plus size markets, and working with big-name clients like Under Armour and Adidas in the clay design process provided its own set of challenges.

“It was a very long process to develop a line of custom mannequins,” Steve explains. “We would have to spend a great deal of time upfront with a client trying to figure out what they were looking for, what the poses were, what the dimensions were, what sizes these pieces were. The armatures would be set up by hand, the sculpting would be done by hand in clay. It would require several visits of the client on premises before we got an approval to move into the molding process to begin production.”

When working with athletic apparel clients, the challenges multiplied. As they started to get into sports-specific activities, posing came to be of utmost importance. “The poses are either accurate or they’re inaccurate,” Steve says. “If you try and put a golf mannequin in a golf shop and he is not in the proper position, the mannequin will be ripped apart by patrons.”

If you want to talk with someone about whether Greneker is in fact a creepy place to be stuck at night, Daniel Stocks is your man. As Senior Sculptor at Greneker – or Sculptor Extraordinaire, as Steve tended to refer to him – he’s the one responsible for following through on all those client requests.

“A lot of the time I would work late at night making all these adjustments and changes while the people are in town so that they [could] see it the next day,” Daniel recounts. And that was after starting from scratch on the figure: constructing a metal armature and building up the clay by hand.

True to their trailblazing past, Greneker began searching for ways to update their process and make themselves more efficient.

“We started to look at digital as a way of creating these pieces, and creating them precisely and accurately,” Steve recounts. “We’ve now moved from clay sculpting to everything being 3D printed, which has helped us in a myriad of ways.”

The 3D Printed Mannequin Challenge

Greneker dipped their toe into 3D printing with a smaller-scale CubeX and quickly realized the potential of the technology.

“We felt as a company that this was the direction that we needed to take, and we needed to go full steam ahead before some of our competitors became aware of the technology and started utilizing it,” Steve shares. They wanted to gain the competitive advantage before others caught wind of what they were doing. “And that’s one of the things we have done, we’ve positioned ourselves as the experts in this type of mannequin design.”

They purchased a few other small 3D printers, and then Daniel began the hunt for a large-scale printer with the right price tag. He came across Gigabot.

“Well, there was really nothing else on the market within a reasonable price point that would make pieces big enough for a full body,” Daniel muses.

“We selected the printer based on, again, the human body,” Steve explains. “We’re a mannequin manufacturer. We wanted larger printers to be able to print torsos and legs.” Their 3D printer arsenal includes a range of machines, from small-scale printers good for the details on hands and faces, up to the large size of Gigabot for cranking out large pieces.

“The challenge for us and my challenge to Daniel was to get a full-sized mannequin printed in one day,” Steve smiles. “It takes about 250 hours of print time to print a mannequin. In order to print it in one day, it was going to take a bunch of machines.”

Take a stroll through their office and you’ll come across the realization of this dream: a separate room tucked within their main sculpting area which they built specifically for 3D printing. “The Gigabots work fantastic for large-sized pieces, so we bought a bunch of them,” Steve recounts. Greneker is now up to four Gigabots – stacked two-by-two and suspended from the ceiling – which they house in this room along with their smaller-scale machines so they can run 24 hours a day.

“Before 3D printing, it would’ve been just unthinkable to make a mannequin in a day,” Daniel muses. “Now it’s actually possible.”

“A Myriad of Benefits”

Steve explained that the benefits that came with moving from clay design to digital and 3D printing have been numerous. The biggest savings may be from a time standpoint – they’re cutting from every aspect of the preproduction process.

“We save time throughout the entire process,” he shares.

Because everything is now digital, they no longer have to bring clients in to see mock-ups in person during the design process. “Instead of having clients visit, we can have video conferencing now, which accelerates the initial consultation period greatly,” Steve explains. “The client can sit on the other end – whether they’re across the country or across the world – and in real time we can make those changes and those tweaks to make these pieces exactly what they’re looking for.”

Daniel is particularly happy about this aspect as well. He still sometimes has to work on a time crunch, he explains, but “it’s less physical and it allows a lot more flexibility,” he explains. “If I have to, I can work from home on the computer and makes adjustments. It’s a lot quicker.”

“What,” you may ask, “does he mean by ‘physical?’” Miniature, scaled-down models of a mannequin to show clients weren’t possible before 3D printing, because the mini and full-scale versions can differ so much when working by hand in clay. So, as Steve recounts, the sculptors had to work in full-size clay as they went through the tweaking process, often while the clients were there in person. He explains, “We would bring the client in and then the sculptors would wrestle with the clay in front of the client until we got it to where it needed to be.”

No more mannequin manhandling. “With 3D printing, we take the digital model and we’ll produce a scaled model, usually about 18 inches tall, and then we can send that to the clients,” says Steve. “They can make sure that all the measurements fit where they like and that the posing is what it needs to be in. Once we get the sign-off at that point, then we produce a full-scale 3D print.”

Greneker will print a full-size version of the mannequin, which, with a little sanding and painting, will function exactly like the final mannequin, albeit not in the final material. That gets shipped to the client where the stakeholders can review the piece exactly as it will look in production.

This is immensely helpful for another portion of the process: the sign-offs. In the past, Greneker had struggled to get all of a client’s decision-makers in the room at once. “We would have a group of people come visit us that may or may not represent all of the stakeholders involved in the development,” Steve explains. “Ultimately, whatever approvals or opinions we received at that point could be superseded by someone else that hadn’t been here.”

That frustrating portion of the process is completely removed now. “With this new process,” Steve says, “the model goes in front of everybody, so it’s there for everyone to look at. You get a much, much tighter buy-in much more quickly.”

And of course, in the actual design process itself, the digital realm has also proven itself to be a clear winner over clay. “If you do something in clay, you do it by hand,” says Steve. “You can’t necessarily repeat that.”

No one is likely a bigger fan than Daniel. “It opens up a lot of new tools,” he explains. When designing a head, for example, he can take advantage of the symmetry tool in CAD. The work he’s done on one side of a face is automatically mirrored to the other. “Before, working in clay, we would have to try to make adjustments – ‘Which ear is higher? Are the eyes straight?’ Things like that it makes much simpler.”

It also aids with consistency and continuity if different sculptors are working on the same body. “If I have a large project and I have three sculptors working on it, because it’s three sets of hands, it may not look identical,” Steve explains. “With the digital design, we don’t have to worry about that. The design is the design and you can move it, change it, scale it, but it’s always the base design and it’s always obvious what it is, no question.”

The slashing of time from every part of the preproduction process goes hand-in-hand with cost-cutting. “Internally for the business, the change has been much more cost-effective,” Steve shares. “When I started, we would create lines based on – when it’s all said and done – it’s spaghetti on the wall. It’s our best guess of what was going to sell. We don’t have to do that any longer.”

That gamble used to be a risky one.

“When we did it in clay, you had to commit to it. Clay’s only got a very limited shelf life,” Steve explains. With CAD replacing clay at Greneker, there’s no more wasted effort and materials going into a design that doesn’t sell. Now, Steve says, “We can put a design that we think is cool together digitally and it can sit there as a model until there’s a market and a place for it.”

An Industry in Flux

“The apparel retail industry is in a great deal of flux right now,” Steve explains. “Online sales have really started to affect their brick and mortar sales. I don’t foresee some of the large scale roll-outs in malls in the near future, but what we do see is the need for smaller runs of more specific posing.”

And this – thanks to their calculated research and work – is where Greneker excels.

“What we see going forward is we need to be much more nimble, much faster, and much more cost-effective on the development side so that the retailers can afford to bring in specific mannequins for specific markets,” says Steve.

Greneker’s hard work to modernize and streamline their mannequin production process has paid off. “The marketplace is requiring speed to market. Everything has got to be done sooner rather than later,” Steve explains. “When we would sculpt and create a new line by hand, the process could take upwards of six months in preproduction. In 3D printing, now we’ve reduced that process to where it can be as short as just a few weeks.”

The tedious parts of their old process -the gambles on trends, the risk of botched posing, building up new armatures and clay bodies by hand, the endless on-site client visits to make tweaks and get approval – all of that is now off their plate.

“Right now, we’ve just finished realizing our first set of goals with 3D printing,” says Steve. “Our future goals: we’re going to bring in as many printers as it takes to be the absolute fastest to market as we can be. We want to stay ahead of our competition.”

The Fire Station Gigabot

Chuck Grant wasn’t with the Magnolia Fire Department in 2011 when the Riley Road Fire happened,  but the effects of the massive blaze on the department he now works for as Assistant Fire Chief and Chief of Technology are still visible.

The fire took 10 days to contain and burned nearly 19,000 acres in Magnolia, Texas, northeast of Houston.

“The fire was in such a size that it knocked out cell service in a lot of areas,” Chuck recalls. This meant that the department’s typical public alert methods using Facebook, Twitter, and other cellular-dependent mediums were off the table. They had no easy way to communicate with the community they were trying to help.

What the firefighters found is that when residents didn’t know where to go or what to do, they came directly to the fire station to try to get information. But in a large-scale disaster like this one, that was a problem. “There was no one in the fire stations because they were all dealing with the emergency,” Chuck explains. The fire exposed a serious communication problem they realized they needed to remedy.

When Chuck joined the team, he began working with the Fire Chief to devise a solution to this problem.

What they came up with was something akin to a tool that many businesses use for public messaging: LED signs. The signs would be out front of each of Magnolia’s nine fire stations to display updates and actions during large emergency events, with the ability to change the information quickly and from the field.

The next order of business was aesthetic – they wanted to add a symbol of the fire service to the signs to make them their own, something that would look good for the community.

When they settled on the idea of a large fire hydrant statue on either side of each station’s sign – two at each location meant 18 in total – the next challenge became how to get them made. They started investigating options like fiberglass and bronze casting, but quickly realized that everything was far out of their budget.

That’s when they found Gigabot.

The sign project in conjunction with other potential uses for 3D printing at the station made getting their own Gigabot and fabricating the decorative hydrants themselves the most cost-effective option. Chuck already had a background in 3D modeling, so designing the hydrants was no problem. “It was just a matter of scaling something up from, say, an inch tall to 99 inches,” he said. “And the Gigabot was able to do that for us.”

The build volume of Gigabot was the original draw for their sign project, but in order to make the purchase financially worthwhile to them, they wanted the bot to have a second, longer-term use. This is where the RFID tags enter the story.

Fire stations operate under a system of strict regulations: a truck must have a certain amount of equipment before it can respond to emergencies, and this equipment has a variety of imposed lifetimes that need to be tracked. Chuck explains, “When I started 35 years ago in the fire service, no ax had an expiration date on it – either it worked or it didn’t. And now that’s all kind of changed. So the need for technology has really, really ramped up.”

On top of this, equipment must cycle in and out of the repair room as it’s damaged. A tiny crack to a mask takes that mask out of service until it’s fixed. Keeping track of what equipment is damaged, what needs to be replaced on trucks, where damaged equipment is in the repair process – they’re all more processes that need to be tracked.

All of these components add up to quite the logistical headache for fire stations: monitor the ticking clocks on your equipment to make sure active tools are not outside their expiration dates and take things out of circulation when they are, keep track of damaged items in for repair, and ensure your trucks have all the equipment they need to be ready to respond to a call at a moment’s notice.

It’s quite the operational feat for organizations whose main function is to save lives and battle fires.

In the interest of allowing firefighters to do what they do best, stations are looking for ways to manage all their equipment tracking in the most efficient way possible. Magnolia Fire found a solution in RFID tags from Silent Partner Technologies. The small radio frequency identification devices have an adhesive on one side to affix them to objects and they can be scanned from a distance and tracked via software on a computer. Chuck explains, “It very quickly gives the firefighters the chance to scan the truck and know that the vehicle is ready for them to respond to a call the minute they come into work.”

The problem was, Magnolia quickly realized that the harsh firefighting environment in conjunction with the wide variety of materials they had to tag was proving to be too much for the adhesive tags. “Because the fire service is a tough place to be a little tag, the adhesive strips on the back don’t hold up as well as they would in another application,” he explained. Heat from fires, water from hoses, and the general physical battery that the firefighting tools endure took their toll, and the department found themselves returning from events sans many of their RFID tags.

A solution, they realized, lay in 3D printing.

Using Gigabot, Chuck has been printing small compartments for the RFID tags to fit into which they can then mechanically fasten to their tools. 3D printing the tag holders provides a uniform material to which the adhesive can adhere, while also tucking the tags away where they can’t get bumped off. And they can do this all without altering the form and function of their well-designed equipment.

“All of our items have been well-designed, they’re well-engineered, and so for us to just take something and stick it on the side of it isn’t really a great option,” Chuck explains. What they’re doing is replicating a certain component of an object and building a pocket into it where they can hide a tag. The clip of a flashlight, for example, is replaced with its 3D printed clone, plus one RFID tag that you wouldn’t know is there. This becomes infinitely important when when you’re in a smokey room with thick gloves on, where a foreign part on a familiar tool can lead to dangerous confusion.

If the sign project was what led Magnolia Fire Department to Gigabot in the first place, creating custom RFID tag holders for their equipment is what kept them coming back. It’s proven to be the long-term justification they wanted in order to get their own 3D printer on-site.

“We certainly had this sign project that’s important…it’s going to be the thing that people notice the most because it’s going to be out in front of the building,” Chuck says. “But long-term, to get the most out of our investment, we need that secondary…task for the Gigabot to do.” The ongoing RFID project checks that box.

Gigabot has also proven itself as a problem-solver for issues that weren’t necessarily originally on Magnolia’s 3D printing radar, as the department now has the ability to produce any sort of custom-made pieces they desire. “Instead of going into the marketplace and kind of having to mold to what is available, we can meet our own needs by drawing our own parts and printing them,” Chuck explains.

An example of one such piece is an ingenious yet simple part to hang the firefighters’ masks inside the trucks, keeping them off the seats and floor where they’re more likely to get damaged, and hanging them in a way that doesn’t put stress on the facepieces. The clever design fits into the masks where the firefighters’ air tanks connect; with one twist they lock onto the piece so they can’t fly off en route.

The station’s service room is lined with equipment in for repair, including a table full of dinged masks. Much of the damage was due to them being tossed around inside trucks or hung in a way that puts undue stress on the temples of the masks, causing them to crack over time. This new piece, they explain, solves these problems and was infinitely simple for them to manufacture.

Clessie Hazelwood, Battalion Chief at Magnolia Fire Department, originally saw the design 20 years ago at a different fire department. Chuck prodded him to talk about how much effort that department had to go through to produce one. Clessie sighed, “Oh…they had to do machining, set up dies and everything.” It was a long, costly process.

When Magnolia got their Gigabot, Clessie came to Chuck to see if the part was something he could print for them. Chuck chimed back in, “From the time you told me about it ’til the time you held it in your hand, how long did it take?” Clessie paused.

“Less than a week.”

3D Printing Products for Refugees

The Gigaprize is a competition we run for every 100 bots we sell to donate a Gigabot to an organization that will use it for good. Scott Key originally saw the call for contest entries on Instagram.

He and his business partner, Sam Brisendine, thought the odds of them actually winning were pretty slim, but they decided to give it a shot anyway. That decision ended up paying off handsomely.

The winners of the 400th Gigabot are Good Works Studio, a Houston-based design firm specializing in products for refugees.

Sam and Scott met as students at the Rice University School of Architecture, where they developed a sort of Swiss Army Knife crate of supplies for refugees as a class project. The crate itself broke down and transformed into a floor, and as time went on, they came to realize that the most valuable part of the whole package was not the cache of supplies inside but the box itself. Emergency Floor was born.

Thus a school project gave birth to Good Works Studio, the company that the two cofounded specifically to develop products for the refugee space. Their first product, Emergency Floor, is a modular flooring system for refugee camps that can be quickly installed and configured to the varied layouts and sizes of different shelters.

Flooring for these refugee camps provides families with something more than just comfort: safety. The flooring acts as a thermal break between the cold nighttime temperature swings of places like Iraq and Lebanon, as well as a means to combat the higher rates of diarrhea and parasitic infections that come from living in the dirt.

Emergency Floor is just the first product that Scott and Sam have released to tackle problems faced by millions of refugees around the world, and they’ve got more in the works. However, the design and prototyping process that goes into developing products like these is not cheap, and Good Works Studio is a young, cash-strapped, two-man company whose founders work separate full-time jobs to pay the bills. They ran a crowdfunding campaign to get Emergency Floor off the ground, but they knew that the money and time needed to take future ideas from paper to product would be prohibitive.

Traditional manufacturing and tooling isn’t the most forgiving when it comes to the design process. Get a mold made and then decide you want to tweak something in your design, and you’ve just gotten yourself a $15,000 paperweight. Perfecting the design before moving on to manufacturing was imperative.

“Previously we had outsourced 3D printing and other prototyping methods,” Scott explained, but, as he went on, “It was just going to be an impossibility to do the amount of iterations we needed to get a product to where it needed to be.”

Having an in-house 3D printer was the dream.

For Scott and Sam, Gigabot is an enabler. Having a 3D printer of their own means getting well-designed products into the hands of people who need them more efficiently and effectively. They can send a design file to print in the morning, have a prototype in their hands by the afternoon, and start printing a modified version before they leave at the end of the day. This ability to iterate their designs quickly and in-house allows them to move through the prototyping process much faster and less expensively than any other avenue.

The overarching vision that drives Sam and Scott is a desire to help those in need around the world through design. The next product they’re working on is a device that can be installed into any shelter to act as an air conditioner – sans electricity – using the Venturi effect.

Our aim with Gigabot is to enable others to create products that make this world a better place, and the Gigaprize is our way of making this technology even more accessible to people who will do just that.

As Sam put it, “Design can do good for those who can’t afford it.” We couldn’t agree with him more.
