RapidMade looks forward to including these revolutionary nylon powders in its operations.
One of the most enjoyable aspects of working with entrepreneurs is seeing them – and their projects – come to fruition, orin Lizz Hampton’s case – to nutrition! Lizz is one of our favorite success stories, especially given that she is among RapidMade’s first customers, dating back to its first year in business.
Lizz came to us with a product idea that would make it easier for people to make fresh nut milk at home. The product concept itself was very simple, however the design requirements were very complex.
Over the course of the past 4 years, we have worked with Lizz to simplify this revolutionary product through hundreds of prototype iterations, helping her streamline from more than 15 complex parts down to 4 simple parts and then supporting her pivot away from a device into a reusable, mess-free nut milk bag.
“I wouldn’t have been able to get this far without Micah and his team at RapidMade. Not only did they help me develop a better product, they provided essential insight into how it would need to be manufactured, important engineering considerations and top quality parts for my prototypes. Above all else, they have been there to support me on my journey and believe in the product I am creating, which is invaluable to me as a young maker/designer. ”
As of October 17th, Lizz’s reusable, mess-free nut milk bag is available for pre-order on Indiegogo. We are helping her spread the word about her launch because we believe in supporting our customers and doing our part to help them succeed.

Growing up in Pittsburgh, if you weren't directly connected to the Steel industry, you complained about the rotten egg smell and pollution. But when the industrial giants went silent in the 70s and 80s, the complaints shifted dramatically to the economic tragedy that was unfolding - the flight of life-long residents and well-paying jobs. Rhetoric from the recent election aside, Pittsburgh's manufacturing base is both alive and well...
“The Pittsburgh Regional Alliance (PRA) recently reported that in 2016 the manufacturing sector accounted for the most investment dollars ($6.1 billion), the most deals (50 companies expanding or relocating), and the most new and retained jobs (3,667).”
But as we've continued to see, the type and number of jobs that have been created don't resemble those of the steel-era in any way.
“Manufacturing is the most active sector in southwestern Pennsylvania,” explains PRA President David Ruppersberger. “But as technology and automation continue to transform this legacy sector, the reality is that manufacturing facilities will be smaller-footprint, high-efficiency environments where fewer workers, with advanced skills including STEM proficiency, will produce more goods. This is a trend that won’t reverse at any time in the foreseeable future.”
Hearing of Pittsburgh's adoption of additive manufacturing and other advanced technologies is encouraging if the resulting economic turnaround benefits the greater community.
FASTER NYLON PARTS – A New Age for 3D Printing
A RAPIDMADE WHITE PAPER
By Mark Eaton
Getting parts on demand has been a manufacturer’s dream for many years. Since 2005, see M. Park, UNSW article, there have been cries from the 3D printing industry that additive technology would replace the need for injection mold tooling, that it would eliminate the need for machining, that casting would become obsolete. Finally, that dream is becoming a reality.
While there have been success stories such as the use of Stratasys Ultem for aerospace parts and selective laser sintering (SLS) nylon for automotive parts, until today, these components have all had restrictions on where and how they could be used. One of the biggest drivers for this has been the speed and the part cost. Siemens, according to a recent article in Plastics Today, is using 3D printed fire, smoke and toxicity-compliant polymers to replace parts in trams, and they cite part availability as being the primary driver. The US Marines have recently experimented with printing replacement Humvee parts in the field. What all these examples have in common is they are limited in scope by the 3D printing technology restrictions. While the FDM process eliminates tooling, it is still 100x slower than injection molding or machining, and while SLS material prices have been reduced, they are still 10x more expensive than injection molding or nylon bar stock prices. So, the extent to which these older 3D processes can be deployed is still limited by cost and speed.

This is beginning to change. A new breed of additive manufacturers is arriving on the market who are focused on truly using 3D printing to create production parts at costs comparable to injection molding and machining prices. These “new age” additive manufacturing companies combine faster printing technology with engineering resources to convert and certify part performance. They have integrated quality systems to ensure material, process and part conformity. And they offer parts at competitive prices compared to injection molding or machining costs without the need for tooling, set-up costs or inventory carrying costs. An example of one company taking advantage of this new age in additive manufacturing is Daimler, cited in a recent Reuters report, who has announced it will start offering plastic replacement parts printed at local service centers from a library of 3D files.

As an executive board member in the additive manufacturing community, I recently got to profile one such Portland-based 3D printing company, RapidMade. After 6 years developing prototyping, tooling and engineering services to support 3D printing, this company is reinventing itself to use the new breed of additive technology being offered by companies such as Hewlett Packard and Carbon 3D. These companies have developed much faster 3D printing technologies that use faster curing, less expensive materials with all the properties of traditional polymers. The new HP MJF is being showcased by RapidMade as part of its expansion in 2017. With speeds that are 10x faster than current SLS technology and material prices equivalent to injection molded nylon or machined bar stock, RapidMade can now offer its customers a wide range of new and replacement part solutions. Where precision tolerances are required, the company uses automated machining centers linked with the printers to provide finishing operations.

Without the need for tooling, customers can now order parts to print using their 3D library or one provided by the service provider. The shorter printing cycle times mean that it is no longer necessary to hold more than 1-2 days’ inventory for quick use parts, and less frequently used parts can be ordered as needed with zero inventory requirements. For very low order quantities (less than 10 parts), it has always generally been cheaper to 3D print versus using traditional manufacturing. With the lower cost breakeven point of these new age 3D printing technologies, minimum order quantities (MOQ) of 500 or 1,000 will be converted to printing versus injection molding or machining. For customers already using SLS technology, they will see an immediate cost and turnaround benefit from switching to this new breed of 3D printing technologies.
The benefit of these “new age” additive manufacturing companies like RapidMade is being immediately felt by the machinery manufacturers and end users of such equipment. There is a significant cost benefit in current supply chains, PWC Strategy& estimates there will be a 20% gain in TCO (total cost of ownership) from 3D printing replacement parts. It is estimated 70-80% of that can be delivered to the end users when they engage with a “new age” additive manufacturing company. Lower prices for spare and replacement parts are possible with piece of mind that the part has been certified for use. No longer are machinery manufacturers tied to traditional injection molders who retain tooling that cannot be easily moved. Parts produced offshore can now be re-shored without needing to recreate tooling. PWC Strategy& predicts German spare parts manufacturers will derive $3Bn in benefit from adopting 3D printing. Additive manufacturing by its nature is a non-labor intensive process, and the new breed of technologies produces 10x the number of parts in the same time lowering the overhead cost per part and making larger MOQ more attractive. Companies like RapidMade retain digital libraries and ship direct, on demand parts in quantities of 1 to 1,000 in less than 24 hours. They do this by not only having faster 3D printing technologies but also using automated transaction systems, integrated engineering and lean techniques to optimize printing uptime.

Whether it is Daimler, deciding to print plastic parts locally to save warehouse, shipping and logistics costs or Siemens citing the increased ability to service multiple customers with parts on demand, times are changing for the benefit of producers and end users. And to support the changing demands, these companies are turning to the ‘new age’ additive manufacturers who, in turn, are enabling US companies to re-shore production, improve turnaround time and lower part costs. If you have dismissed 3D printing in the past, it might be time to take another look.
My standard-issue wrist plate may soon be a thing of the past...
When I shattered my wrist in 2014, the surgeon pieced together the fragments using a standard-issue, low-tech wrist plate and permanently screwed it into place. Now, with the recent FDA approval of Additive Orthoapedics' 3D printed Locking Lattice Plating System, patients may soon have access to customized plates for "stabilization and fusion of fractures, osteotomies and arthrodesis of small bones."
“‘We are excited to be one of the first companies to leverage the geometric flexibility, clinical advantages and manufacturing cost benefits of additive manufacturing in the orthopaedic plating market. These plates can be implanted either alone with locking or non-locking screws, or in conjunction with our 3D printed bone segments through the use of a connection screw. This allows the surgeon to mix and match any wedge and plate combination for various deformities, complex revisions, or other limb salvage procedures,’ president Greg Kowalczyk said in a press release.”
Since I have subsequently broken a foot and my other wrist, I will be sure to keep this company in mind, just in case.
Adidas' Futurecraft 4D (Reuters/Joe Penney)
It seems that 3D printed shoes are one step closer to reality. This is a timely story for me as I just went shoe shopping this week... Every time I need new tennis shoes, I go through the same routine: choose from the limited selection of wide sizes and then, through process of elimination, find a pair that I can tolerate. I speed walk, so the shoes have to be large enough to fit my feet but be snug enough to stay in place while I put them through their paces. Based on this week's workout, the pair I just selected are not working out. So I'm always interested in hearing about 3D printed shoes.
Adidas is apparently leading the pack pursuing a technology to allow mass produced custom shoes. They announced a
“new partnership with Silicon Valley start-up Carbon (which) allows it to overcome many of those difficulties to produce a sole that can rival one made by an injection mould, and at a speed and price that allow for mass production.”
The Futurecraft 4D shoe's introduction is planned for 2018 with the intention of offering shoe soles for individual fittings and limited editions.
The partnership with Carbon should allow Adidas to reduce the time it takes to produce shoes by additive manufacturing. Its 3D printer design is reportedly 10 times faster than traditional 3D printer designs, printing soles in as little as 20 minutes.
Paper Packaging, Pittsburgh landmark, closes this week
This week, Paper Packaging closes after 53 years in business. Why would RapidMade be marking this occasion you may ask? Its founder, Dan Unico, who worked every day in 2D printing and box making, is the father/grandfather of three of RapidMade's owners.
Dan, who also turned 90 this month, will continue to work along with his wife Joan, 85, and two sons Ken and Mark to dismantle, crate and ship equipment to new owners. In the spring, they anticipate - finally - retiring. Maybe...
Dan and Joan taught us that starting a business was - and is - a path to a better life. And we learned that lesson at an early age. As children, we would play in the factory, sometimes doing odd jobs until age and experience allowed us to "graduate" to working on the various print and die-cutting machines. This was NOT additive manufacturing. The work could be hard, dirty, and monotonous.
It is a testament to Dan that his wife, three of his four children, one son-in-law and one of his grandchildren (so far) has chosen manufacturing as a career. That is a legacy one can be proud of. Happy Birthday and Happy Retirement!
congratulations!
RapidMade Accelerates Pace and Elevates Quality of Product Launch
Injection Molding Case Study
3D Printing, or Rapid Prototyping as it is also known, is a much faster and cost effective solution for testing and perfecting digital designs. Its ability to fabricate parts overnight without any direct labor, programming or tooling means 3D printing technologies carry many advantages over traditional technologies like injection molding for short turns and small-batch production.
Sometimes 3D printing only goes so far when developing and manufacturing products in their early stages. In those instances, Rapid Injection Molding can take products to the finish line.
An American-made LED light bulb manufacturer engineered a version that was bigger and brighter than its competition. The company quickly learned that RapidMade's injection molding expertise could test, validate and even manufacture its light bulbs in ways that 3D Printing simply could not match.
RapidMade accelerates the typical injection molding process by providing a short cut between prototyping and production tooling. After the rapid prototyping client finalizes its product for injection molding, RapidMade creates a cheaper and better solution by making pre-final tooling out of aluminum. This option allows customers get to market sooner than other injection mold processes and helps gain customer feedback to improve products. Getting a product to market sooner generates more revenue to invest in further product development and long-term tooling.
Material
Since the customer didn't know what the final material of the bulb should be, cutting the mold and testing multiple materials, including different grades of ABS and Polycarbonate, helped pinpoint the final material and even helped estimate eventual mass manufacturing costs. Additionally, electronics products must go through rigorous UL testing to ensure consumer safety before the product can be sold in stores.
Color and clarity are other traits vital to the lighting industry. Because 3D printers must run manufacturing-grade material that is unadulterated, optimizing these characteristics can be difficult. With injection molding, however, one can custom blend different clear and opaque pigments with clear plastic to prototype different levels of clarity and color. So the company could test very specific color profiles to perfect its formula in the final product.
Finish
Finish is extremely important when working with lighting, as well as other consumer products. A matte finish diffuses light at a very different rate than a polished one. Due to the layered nature, inherent in the 3D printing process, even the highest detail machines will have some level of surface striation. Additionally, most filament or powder technologies will have a very rough finish beyond the layer lines. Achieving custom finishes requires polishing, sanding, and painting of each individual unit, making it is extremely labor intensive and expensive.
Alternatively, injection molding shoots molten plastic into a cavity which picks up the texture of that cavity. That means one only needs to finish a mold once to get repetitive shots of that finish. And molds can be polished and textured to prototype a variety of finishes before settling on the desired one.
Volume
A light bulb is a relatively low-cost consumer good. These goods are meant to be sold in large volume at low cost. Tooling to produce those volumes inexpensively enough can take months to make and require high upfront investment. Many businesses are interested in small and medium-batch options that are more cost effective and higher quality than 3D printing to excite investors, test markets and stoke demand.
The company secured a prototyping option with relatively little upfront investment that served as a bridge tool to get actual product out into the marketplace. Aside from the aforementioned quality concerns, this could not have been cost effectively achieved with 3D printing; one cannot sell a light bulb where the housings cost $38 to the manufacturer. Creating large volumes of parts on a 3D Printer can also take much longer than injection molding, making it harder to fill orders. Injection Molding can really provide exceptional value to early-stage manufacturers when producing runs of hundreds or thousands of parts for low cost very quickly.
Our friends at Direct Dimensions in Owings Mills, Maryland, will be "creating a 3D CAD model" of the Roberto Clemente Bridge in our hometown of Pittsburgh, Pennsylvania. The resulting files will then be used to create 3D prints of the bridge for an upcoming RAPID + TCT show being held in Pittsburgh in May.
Pittsburgh, long recognized for its sports accomplishments, is becoming well known as a Center of Excellence in Additive Manufacturing as well.

RapidMade especially enjoys working on projects designed to improve the lives of others. And we are thrilled when we get to see them "in action." Recently SweetSense asked us to 3D print SLS parts that were used to produce remote sensors in Kenya that allow residents to better maintain water supplies and sanitary latrines.
According to Taylor Sharpe, SweetSense is a "social enterprise" that is a spin-off of the Portland State SWEET Lab and partners with other agencies to provide high-tech solutions to problems faced by residents in developing countries.
“...in one case monitoring boreholes (deep water pumps that service 100s to 1000s of people) in Isiolo and Turkana counties in Kenya; and in the other case helping manage collection routines and operator issues of Sanergy Fresh Life latrines in the Mukuru informal settlements outside of Nairobi, Kenya.”
For one of its initiatives, it has partnered with Sanergy to produce a
“rugged enclosure that contains an occupancy sensor and am RFID reader, to respectively estimate the fill level of latrines before conversion to fertilizer and to give Fresh Life Operators a direct line of contact with Sanergy HQ in the case of emergencies.”
In another, the Sat Spacer, SweetSense worked with Kenya RAPID...
“RapidMade parts were used to allow SweetSense to provide satellite-based monitoring in areas with no cellular coverage.”
SIEVGEN 400-US: Photo Credit - Farleygreene
When I worked for Nabisco, we had large robust sieves that would prepare flour being drawn from our 7-story flour towers prior to discharging into the weigh scales and mixers - several hundred pounds each batch. The contraptions looked like very large metal boxes that shook and rotated violently to sieve the flour. So it makes sense to me that a similar process would be recommended to pre-treat metal powders before being sintered into a 3D print.
In fact, a couple of challenges using powders in manufacturing processes are material purity and particle size. Apparently Farleygreene has introduced its SIEVGEN 400-US specifically to address these concerns for DMLS additive manufacturing.
“According to Farleygreene, when in normal use the system provides for a completely sealed and dust tight process. The feed hopper is docked into place to feed the sieve unit with a self-sealing interface and the media is introduced through an internal metering device designed to ensure the optimum screen dwell time to recover as much useable material as possible.
Oversize powder is continuously removed and ‘good’ product falls through the ultrasonically excited mesh. The screened media is filled into a receptacle locked into place on a mobile dolly to reduce manual handling as much as possible and allow the operator to move the product to where it is required.”
When you are hitting a potentially explosive metal powder with a laser, powder consistency and purity are obviously important material attributes to control.

RapidMade gets to work on many cool new product ideas. Given our love of dogs - we have a dog-friendly workplace, this project has been a favorite...
"OMDOG performance canine headgear started as a simple idea — to build a custom helmet for Charlie the Dog, who rides around Portland, Oregon in a cargo bicycle. When the decision was made to duplicate and improve the design, we contacted Rapid Made. They were responsive and excited about the project. They quickly 3D scanned our prototype, reverse engineered it, and made it easy for us to review and approve the CAD model before printing. Rapid Made helped us take an idea that started as a cardboard model made from a pizza box turn it into a viable product design. They're providing us with manufacturing options within our budget and well suited for our target market. We are extraordinarily grateful to have found Rapid Made!"

One of the juicier projects we've had involved 3D scanning real 10-lb crabs to recreate life-like replicas for Bering Sea Crab Fisherman's Tour. The captain and his crew take tourists out on the high seas in the summer to watch them work. Unfortunately, they were losing much of their inventory recreating their catches - this was both costly and unsustainable.
Once we 3D scanned the real thing, we 3D printed a master pattern which was used to create a mold. The mold allowed RapidMade to cast the crab look alikes in urethane rubber. See the results here.
