Cutting 3D Printing Costs with an Open Source Material Pelletizer https://ift.tt/2SkzwZM Good filament can be pricey, although the polymers the filament is made from aren’t that expensive. That’s the opening observation of a paper entitled “3-D Printable Polymer Pelletizer Chopper for Fused Granular Fabrication-Based Additive Manufacturing.” The authors argue that the markup can be avoided by eliminating the process of creating filament and instead 3D printing directly from polymer granules. Fused granular fabrication (FGF), or fused particle fabrication (FPF), they point out, is held back by the lack of accessibility to low-cost pelletizers and choppers. So they developed their own open-source 3D printable pelletizer that can process both single thermopolymers as well as composites. A single motor version of the system can be fabricated for only $185. All of the parts can be 3D printed with PLA or any other hard FFF thermoplastic, except for a few parts which are specifically designated to be printed with NinjaFlex. Step-by-step instructions are given for assembling the 3D printed parts. After assembling the machine, the researchers tested it with a number of materials: both 1.75 and 2.85 diameter PLA and ABS, as well as PP, PETg and coffee-filled PLA. They also tested NinjaFlex, but found that it was too flexible to be processed. A prototype Gigabot X 3D printer was used to 3D print the materials, and a self-designed “recyclebot” was used to create PLA filament from the pellets.
Recycled material, such as PET and PP, can also be used from post-consumer materials, chopping up things like water bottles.
Thermopolymers that have been shown to be acceptable for the recyclebot process include PLA, HDPE, ABS and elastomers, as well as composites such as waste wood biopolymers and carbon fiber-reinforced plastics. Future work includes replacing some parts such as the DC motor with cheaper alternatives, as well as working on geometric improvements that would allow flexible filaments such as NinjaFlex to be chopped.
Authors of the paper include Aubrey L Woern and Joshua Pearce. Discuss this and other 3D printing topics at 3DPrintBoard.com or share your thoughts below.

Disruptive innovation
, a term that was first popularized by Harvard University professor Clayton Christensen, is a concept in which companies continue investing in the development of their established products, and at some point exceed the basic requirements of many of their customers. Disruptors introduce products that meet market needs through lower cost and/or more convenience, and disruption, in turn, often results in a change in the business system. Back in 2013, Christensen noted that disruptive innovation can create a new market and value network, and will end up disrupting an existing network. 3D printing in manufacturing, and this concept of disruptive innovation in particular, are the subjects of a dissertation, titled “The Promise of the Future: 3D Printing in Manufacturing,” written by Dr. Michael G. Westphal and submitted to the University of the Rockies in Colorado.
We should all know by now that adopting 3D printing in manufacturing operations can help companies save money and time. But, as Dr. Westphal put it, the future is leaning more towards 3D printing touching “the lives of consumers at every level.”
The dissertation takes a look at some of the main inhibitors and enablers to the adoption of AM through the frame of a qualitative case study on small-to-medium sized manufacturing and parts production in the state of Colorado.
Using the following open-ended questions, Dr. Westphal interviewed several representatives from area companies:
Each of the interviews lasted about an hour, and eight themes in regards to “tactical considerations for the use of 3D printing at the manufacturing site” emerged from the findings: the cost of investment, part complexity and design, materials consideration, prototyping and rapid prototyping, speed, part quality, part quantity, and access to a workforce that was trained in AM. Three additional findings, relating to but separate from the aforementioned themes, were production workflow and lights-out manufacturing, knowledge base and perception issues, and risk management and precipitating events. While perceptions on the use of 3D printing on the factory floor differed between the interviewees due to “where they fell on the continuum of current use” and the kinds of manufacturing, each of the participants did agree “that the future of manufacturing will include 3D printing and additive manufacturing in some way.”
Dr. Westphal said that all the participants did agree on one thing – the pace of change in the AM marketplace gives them reason to pause. Additionally, nearly 77% of the study participants said that 3D printing can’t disrupt the industry until a culture change happens.

Makelab Founders Expand Business with Makelab Market for 3D Printed Interior Designs https://ift.tt/2zxc1FH Christina Perla and Manny Mota started Makelab a few years ago as a way to offer customers help with bringing their 3D printing ideas to life. They founded the Brooklyn-based company on the principles of innovation and sustainability, and have shown a seemingly unending reserve of energy when it comes to improving and expanding their business. Recently they decided to turn their attention to the creative side of 3D printing and launched Makelab Market, a marketplace for 3D printed home interior designs. Just in time for the holidays, Perla and Mota have introduced their first collection for the new site, a series of 3D printed planters in a variety of geometric shapes. They have plenty more plans for the site as well, and recently took a moment to talk about Makelab Market’s founding and future. What is the inspiration behind Makelab Market?
What kind of products are you launching with and why?
What kinds of products or materials/finishes do you plan to feature down the road?
What are you each most excited for with the launch of Makelab Market?
3D printing was invented in the 80s but didn’t start picking up steam until the last decade. Why do you think that is?

Florencia Viadana https://ift.tt/2KFSYxm New People of Print Member is Amsterdam-based independent design studio Format Wars founded by graphic designer, photographer and video artist Florencia Viadana in 2017. Viadana grew up surrounded by visual art, her father is a craftsman and sculptor whilst her mother is a painter and her two sisters are also graphic designers! Whilst growing up, a rememberable quote found in a book her father gave her by Wassily Kandinsky (A beautiful, beautiful edition by the way) said: “Empty canvas. In appearance – really empty, silent, indifferent. Stunned, almost. In effect – full of tensions, with thousand subdued voices, heavy with expectations. A little frightened because it may be violated.” Since then, Viadana has always been interested in this line of thought, and has been her way of subsistence since she can remember. When the studio isn’t completing commissions, Viadana always initiates her own projects to keep her happy. Most recently she launched an initiative called ‘Read on the tram’ which aims to encourage reading during the short trips that people make every day on the public transport in Amsterdam. Consisting of a collection of fanzines, in total the series features ten famous writers, the idea, to give them to the people waiting at the tram stop, encouraging them not only to read but to find out more about the author and to complete the rest of the collection as well. Each zine comes with stickers and a card explaining the project, encouraging to visit the website and find out more about it. Click the link below to see more of Viadana’s lovely work.

Researchers Develop Helpful Tool for Estimating Total Costs of 3D Printing AMCET https://ift.tt/2FK69hO While many companies are working hard to lower the overall cost of 3D printing, whether it’s through eliminating post-processing or offering less expensive materials, sometimes it’s just not possible to make the technology less expensive. That’s why Aditya Mahadik and Dr. Dale Masel, a pair of researchers from Ohio University (OU), are focusing on AM cost estimation instead, so users can learn more about the trade-off between cost and design changes. The two wrote a paper, titled “Implementation of Additive Manufacturing Cost Estimation Tool (AMCET) Using Break-down Approach,” about their efforts to create a tool that can help engineers and designers understand the full cost impact of 3D printing at the beginning of the process.
Cost estimation, or CE, can be used to help companies set product pricing, determine business potential, prepare budgets, and perform break-even analyses, in addition to providing customers with accurate quotations and helping entrepreneurs make decisions about manufacturing process and product design changes. How much any given product costs depends on the resources – like tooling, material, machine, and labor – that are used to make it. In order to properly estimate how much a company will spend manufacturing a certain product, it should estimate the cost associated with all of these resources. The OU researchers used a breakdown approach in their AMCET, which calculates the cost components by “taking limited information from the user to support quick CE of a design when manufactured using one of seven different AM processes.”
AMCET calculates the total cost of a part by adding together machine, material, labor, and post-processing costs. The tool separates these four components into five different levels:
In the OU experiment, the estimates that the AMCET generated were validated by using three different 3D printing processes to manufacture two parts, and then compared the results with the true cost. According to the results, the cost of PolyJet 3D printing was estimated with 12.87% error, 14.65% for SLA 3D printing, and 19.14% for FDM 3D printing.

If it’s a really major breakdown, the only option is sometimes to buy an entirely new model. If it’s only one part that is malfunctioning, however, it can often be replaced by a spare part directly from the manufacturer. Appliance manufacturers understand that good business involves taking care of the customer beyond the initial purchase, and that means having parts available for repairs – ideally immediately available, because as anyone with a malfunctioning washer or dryer knows, the sooner the problem is taken care of, the better. The problem is that having spare parts available at a moment’s notice saddles appliance companies with huge inventories of parts that may or may not be required anytime soon. This requires investment in storage space and presents other issues, as well. Often appliance models go out of production, replaced by newer versions, well before customers stop using their older models. Where, then, do those customers turn for spare parts once their machines are no longer manufactured? It’s not always realistic for companies to carry parts for appliances that are no longer in production, which can leave a customer struggling with how to repair an otherwise perfectly good machine that simply needs a single part that is no longer available. On the other hand, if companies carry too many spare parts, they can wind up with excessive amounts of inventory that never gets used, especially once certain products become obsolete. This is a tremendous waste of money and space. So what’s the best solution for both manufacturers and customers? It may be 3D printing. If a company decides to adopt 3D printing for its spare parts, it can eliminate the need to carry physical inventories of parts at all, instead relying on a virtual inventory of parts that can be 3D printed as needed. Even truly obsolete parts can be reproduced by 3D scanning them and creating 3D models that can then be printed. It saves time, space, and money, and allows customers to receive parts within days – if not hours – of requesting them. Singapore startup Spare Parts 3D was founded in order to help companies digitize their spare parts inventories for 3D printing, as well as handling the 3D printing itself for companies that do not wish to invest in 3D printers. Recently, home appliance company Whirlpool agreed to a partnership with Spare Parts 3D. The two companies will work together to scale up the inclusion of 3D printing in Whirlpool’s after-sales services.
The partnership initially started in November of 2017, with a pilot project in Singapore that involved 150 parts. The technical feasibility of the project was evaluated by January 2018, at which point Whirlpool gave Spare Parts 3D access to perform a catalog analysis that allowed them to review more than 11,000 SKUs. These SKUs were reviewed one at a time through Digipart, a proprietary online software that allows the user to estimate the benefits they would get from using 3D printing and determine which parts would be the most profitable. The review found that seven percent of the SKUs were economically profitable and therefore suitable for 3D printing. The first 3D printed part has already been made: a push button printed in Nylon using Multi Jet Fusion technology.
According to Spare Parts 3D, all of the 3D printable Whirlpool spare parts can be produced using three technologies: MJF, FDM and SLA. Five different materials – ABS, ABS V0, PA12, Rubber-like resin, and PP-like resins, will be used to 3D print the parts. While the number of parts being produced with 3D printing is currently limited, the partners expect to deepen their collaboration in the future and 3D print a larger number of parts.
