There continues to be strong demand for the 3D printing and additive manufacturing industry, as pointed out in a recent report from market research leaders PiperJaffray. The research included 79 industry respondents and revealed why they feel bullish on 3D printing and additive manufacturing as a continued growth market for investors.
Here are some of the results of the research which clearly shows that 3D printing and additive manufacturing is a growth industry for investors and also an increasing entry point for new resellers.
Over the past year there has been a sizable increase in the number of resellers that have been operating in the 3D printing/additive manufacturing space for less than five years. This shows a strong growing demand for 3D printing and related service delivery. A lot of this demand and growth comes from new respondents to the research which reveals they are Stsratasys (SSYS) resellers. Stratasys is seeing massive growth in the number of people reselling their 3D printing/additive manufacturing equipment and that has a direct correlation to the growing demand for the related services.
Other resellers such as EOS also reported growth, however, they tend to take a more direct approach without relying too heavily on resellers.
In the attached report (PDF), PiperJaffray outlines all of the detailed market signals which point to their bullish recommendation for investors looking at the 3D printing industry.
New customers needing 3D printing/additive manufacturing services tend to utilize service providers instead of investing in their own equipment and this trend will persist for the foreseeable future as more and more companies leverage the technology.
In Q4, total growth expectations increased 4 percentage points to 17% which represents a slight uptick from Q3, believed to be due to companies seeing the cost and manufacturing benefits of 3D printing.
Due to the increasing reseller demand for 3D printing systems from manufacturers, more companies leveraging 3D printing, better throughputs, better materials and quicker-to-market finish times, market research leaders PiperJaffray feel that the 3D printing/additive manufacturing industry is bullish for investors. Read the full PiperJaffray report, “Q4 3D Printing Survey Points To Strong System Demand From SSYS Resellers” for the detailed analysis, data gathered, and respondent feedback.

What makes Direct Metal Laser Sintering (DMLS) a leading 3D printing technology in 2015? It’s not new news that DMLS prints metal 3D parts. Here are some new exciting new trends that Steve Heller, 3D specialist for the Motley Fool found “incredible”:

Conformal cooling channels manufactured out of 6061 Aluminum open up amazing possibilities for heat sink applications. Direct Metal Laser Sintering (DMLS) metal 3D printing cost effectively allows aerospace, oil & gas, and automotive engineers not only to easily manufacture cooling channels, but to produce conformal micro channels that traditional manufacturing cannot achieve. Since DMLS powder is a 6061 Aluminum equivalent, the thermal conductive properties are also well matched. With held tolerance’s off the machine of +/- .004 and a process that builds parts with highly complex internal geometries, compact heat sinks that maximize surface area and air flow are possible. DMLS melts metal powder layers together to nearly 100% density, also making these innovative heat sinks manufacturable using 3D metal printing.
A recent Plunkett Associates study looked at a variety of methods to build more efficient heat sinks and it concluded that, “The five best performing heat sinks were built using DMLS.” They further concluded that all five cases showed a consistent heat source temperature when compared to traditional extruded and stamped 2D processes. A different IOP Science study examined the impact of DMLS surface roughness on heat sink performance and concluded, ” Our results offer an evidence of the possible impact of DMLS on electronic cooling since a 50% and 20% enhancement (compared to milled samples) is observed for flat and finned heat sinks, respectively… These results open the way for a huge boost in the technology of electronic cooling by DMLS.”
i3D MFG™ has produced several successful heat sink projects for a variety of aerospace and UAV companies using our DMLS Aluminum. In addition to the conformal cooling channels and the surface roughness advantages, client can also produce multiple designs on one build for testing and then come back and do production runs on the bets performing design. i3D™ also 3D prints in Titanium, Stainless Steel, Maraging Steel, and Inconel.

Direct Metal Laser Sintering (DMLS) 3D printing was featured first as an excellent rapid prototyping tool and then as a new manufacturing advancement in two 3D Printing Industry News items over the past two days. So which is it, prototyping or production parts? The fantastic news for designers, engineers, and production managers is that DMLS has been a phenomenal rapid prototyping tool for functional metal parts for years and now it is also a proven metal manufacturing method for complex parts ranging from turbines to heat exchangers.
As Scott Grunewald points out in his article, “This (DMLS) rapid prototyping allows newly developed components to be test installed, articulated and checked for clearance and movement tolerances. The final models can then be used to create the drawings and manufacturing guides that define construction materials, inspection requirements and post processing features. This portion of the process is so fast that the final part is just being completed by the time the approved drawing is released.” Innovations can be tested in working models, using titanium, inconel, tool steel, stainless steel or aluminum and then tweaked and retested in a matter of days. DMLS parts near 100% density, making them comparable or denser than machined or cast parts. 3D metal printing, like other 3D printing methods allows multiple 3D models to be built at the same time without contending with expensive CNC programming time. Aerospace giants like GE and Lockheed Martin have invested in hundreds of DMLS machine to take advantage of this competitive advantage.
While GE and other aerospace players have used 3D prototyping for years, they have also increasingly starting using DMLS for production runs. Sigma Components’s news about its funding and partnership with Rolls Royce to utilize DMLS to manufacture complex functional parts for use in end products highlights the untapped potential 3D manufacturing brings to production. DMLS has progressed in its speed and reliability to the point of becoming a viable process for Sigma to “…redesign and develop lightweight pipe end fittings that use 3D printing and additive manufacturing to reduce the weight of traditionally manufactured components and minimise part and manufacturing costs.” However, to achieve its full potential, designers and engineers must shift their perspective to Design-for-3D, eliminating traditional manufacturing design constraints.
i3D MFG™ is focused on helping its customers realize these manufacturing advantages. With a full team of 3D engineers, as well as its designation as the EOS Material Process Application partner, we not only offer 3D manufacturing, but new DMLS powder development, parameter development, and of course, rapid prototyping.

Spinal implants manufactured using 3D metal printing, or Direct Metal Laser Sintering (DMLS), have been the standard OEM sample to highlight complex latticed geometries. The question being, have any of those cool looking implants been used in the real world? Great new for all DMLS users and manufacturers – 4WEB Medical announced this week that 3,000 of their DMLS spinal implants have been successfully used by surgeons. Even better, the relatively rough surface finish associated with 3D printed metal parts creates an even better patient outcome. According to 4WEB, ” The truss implant designs have a distinctive open architecture, which allows for up to 75% of the implant to be filled with graft material to maximize bone incorporation.The 4WEB Medical ALIF device has a bi-convex surface that brings the implant and graft material closer to adjacent bone across the entire end plate rather than just around the outside edge. This in addition to a unique implant surface texture dramatically improves initial fixation and reduces the chance of migration.”
As a DMLS manufacturer, i3D MFG™ works closely with its clients on surface finish requirements, a commonly misunderstood piece of 3D metal printing. 3D metal parts are nearly 100% dense, allowing for any post process associated with machined or cast parts; however, clients often expect parts to come straight off the DMLS machine with near mirror polish. The reality is that the initial surface finish for a DMLS part before post process ranges form 125-300 Ra depending on the metal. 4WEB’s spinal implant leaves the rough surface which enhances the effectiveness of the implant. This is a huge shift in how we think about design, incorporating roughness as an innovative tool. Not all applications will achieve this type of synergy between the raw DMLS part and function, but as we shift towards design-for-3D, it’s worth taking note of the match between DMLS and medical implant advancements.

Why would a new small business opening in The Dalles, Oregon be newsworthy to Aerospace Manufacturing and Design Magazine? Aerospace is big in the Pacific Northwest and the UAV/UAS giant Insitu is located 20 minutes from i3D™ Manufacturing’s Direct Metal Laser Sintering (DMLS) factory. 3D metal printing has emerged as a critical component in aerospace, rocket, and UAV design and manufacturing, but until 2014, there were no Northwest DMLS service providers. Insitu, Boeing, and the like were forced to use services thousands of miles away, reducing some of the lead time and cost advantages 3D printing is known for. Oregon is defined by innovation and i3D™’s 3D printing technology is at the forefront of advanced and additive manufacturing. DMLS moves 3D printing from the prototyping realm into true production parts manufacturing. DMLS parts are used in final assemblies by Boeing, Lockheed Martin, GE, etc. In addition to aerospace, i3D™ also provides parts for medical and dental device applications, firearms accessory manufacturers, the energy and recreational gear industries, and automotive parts users.
In 2013, manufacturing accounted for 28% of Oregon’s economy, over $65 billion in output. So, its not surprising that the Portland Tribune and Portland Business Journal also featured i3D™ in their Summer 2014 publications. As opposed to traditional, or subtractive manufacturing where parts are carved out of billet, the additive manufacturing process starts with 20-40 micron layers of powdered metal and uses a laser to melt thousands of micro layers together, one layer at a time based on a 3D CAD model – adding material only where the model dictates. The no-waste process enables parts to be built that cannot be traditionally manufactured, including complex geometries, lattice and honeycomb structures, conformal channels, and single part builds of multi-part assemblies. i3D™ prints stock metals including Titanium, Aluminum, Inconel, 15-5 and 17-4 Stainless Steel, and Maraging Tool Steel as well as custom powders created for specific customer applications. The Dalles has a long history of metal manufacturing and gave i3D™ a warm welcome to its community and the Columbia River Gorge region. Both The Dalles Chronicle and Gorge Technology Alliance celebrated i3D™’s headquarters locating in Oregon.

When INDUSTRY and Ti Cycles designed their entry for the Oregon Manifest bike design project, their vision required next generation technology and exotic metals that would then be hand-crafted by artisan bike makers into a premier urban commuter bicycle. Creating a beautiful balance between local artisan and new technology meant designing in a completely different mindset – enter, 3D printing. Keeping it local, INDUSTRY brought Oregon-based i3D™ Manufacturing on board to 3D print components that simply could not be manufactured using traditional methods. Included in these custom parts were intricate handlebars housing a bluetooth smartphone app called My Bike which monitors bike maintenance and alerts you to when a light needs to be replaced or when something goes wrong with your brakes. Another software, Discover My City, has a series of curated rides from five of Portland’s coolest residents, which suggests where to ride, eat and shop. The rider simply gets “buzzed” with the alerts, keeping them connected as they commute. Ti Cycles signature tubing Titanium frames are the perfect way to make sure no wires interfere with the rider and preserve the aesthetics of the bike design. The curves and junctions of parts of the frame also needed to be 3D printed because the tubing could not be traditionally manufactured to hold the lines properly. i3D™ printed fork crowns, front and rear dropouts, head tubes, bottom brackets, and seat clusters for the bike. The titanium printed part welds showed superior strength and seamlessly integrated with the tubing. 3D printing and phone apps aside, in the end, it was the skill and craftsmanship of Ti Cycles that brought the high tech and custom bike manufacturing together to create a perfect blend of utility and elegance. Go see what all the “buzz” is about at 3ders.org, Engadget, treehugger, and Bike Portland.

i3D™ Manufacturing joined INDUSTRY and Ti Cycles in creating a 3D printed titanium bicycle as Portland’s entry for the 2014 Oregon Manifest Bike Design contest. 3D printing is a perfect solution for those wanting to manufacture a tailor-made product. Whether aesthetics, function, weight reduction, design innovations, or exotic metal cost effectiveness are the goals, additive manufacturing is a game-changer for design and manufacture. Direct Metal Laser Sintering (DMLS) produces functional production parts by fuses 20-40 micron layers of metal powders together from a 3D CAD model. Multiple CAD models can be built on a single run, facilitating cost effective single part production, allowing for multiple versions of the same part to be run simultaneously for evaluation, and reducing lead times from weeks or months to hours and days. Exotic metals like Titanium and Inconel become cost effective because DMLS is a no waste process – after the micro lasers are laser melted together, the left over powder is vacuumed back into the machine and reused. Traditional manufacturing of these costly metals often resulted in as much as 70% scrap, making Titanium cost prohibitive despite its perfect match for the bicycle industry’s weight and strength property requirements. While working with Titanium proved more difficult than other DMLS metals, i3D MFG™ added supports and geometry adjustments for structural rigidity and thermal dissipation to offset tolerance and creep issues created by mass, height, and stress relief. Custom latticed parts, innovative fork crown geometries, and organic frame lines were all possible using 3D printing. Design-for-3D erases all traditional manufacturing limitations, including minimum order quantities, machine lines, and complex assemblies. Furthermore, the weldability and post process properties of 3D printed parts is generally better than cast parts and comparable to machined parts.
