After a successful run earlier this year, Massachusetts Institute of Technology (MIT) will offer another session of its online Additive Manufacturing course, led by Professor A. John Hart.
Learn how to design for additive manufacturing
Additive manufacturing (AM) has applications across manufacturing, and Additive Manufacturing for Innovative Designaims to help learners understand how AM will transform the way products are designed and delivered. The syllabus is designed to prepare professionals for implementing 3D printing processes in their own organizations, bridging the gap between the opportunities enabled by AM and the skills necessary to implement it across multiple industries.
The video below, one of more than 80 videos featured in the course, illustrates both the course’s production quality and its core pedagogy: the most successful learning experiences are those which connect the engineering principles behind each process with its capabilities, demonstrated using real-world examples and detailed examination of the components made by AM.
Over the course of 11 weeks, participants will learn:
– The AM vocabulary and workflow.
– The fundamentals of each major AM process, and its associated materials and performance metrics.
– The applications and unique value propositions of AM, spanning from prototyping to production and service operations.
– The design and performance space of AM, including generative design and lattice structures.
– How to design AM parts for production by combining engineering intuition with AM-specific knowledge and AM process, using advanced, cloud-enabled software tools.
– How to prepare parts to be 3D printed.
– How to evaluate the cost and performance value of producing parts via AM, using quantitative models unique to the course.
– A future-forward perspective on how AM, and the broader digitization of production, will change the dynamics of supply chain
The course was developed by A. John Hart, MIT Associate Professor of Mechanical Engineering and director of the Laboratory for Manufacturing and Productivity (LMP) and MIT’s Center for Additive and Digital Advanced Production Technologies (ADAPT). Some of Professor Hart’s previous work has included development of FastFFF – dubbed the speediest desktop 3D printer to date – and an antibacterial filament made from cellulose.
Joining Professor Hart in instructing the course are 5 other MIT faculty members from the departments of Mechanical Engineering Electrical Engineering,Computer Science, and Materials Science. Additive Manufacturing for Innovation Design and Production will also feature dozens of industry experts from companies like GE, Volkswagen, Autodesk, and Deloitte.
At the end of the course, participants will be awarded an Additive Manufacturing Professional Certificate and earn 4.5 Continuing Education Units (CEUs) from MIT.

Doctor swims English Channel to raise money for hospital 3D bioprinter
Andrew Wolf, a 63-year old professor and cardiologist, has completed a swim across the English Channel in an effort to raise money to establish a 3D printing facility for children with heart defects.
Wolf’s goal aimed to raise £20,000 in order to purchase a 3D bioprinter and enable medical model printing at the Bristol Children’s Hospital. According to Wolf, this technology could “transform” the lives of babies and their families, improving surgical planning of complicated procedures. The unit will also enable the team to explain and show in detail to parents and children what the problem is and how it can be fixed. Wolf believes that this cutting-edge technique would be one of the first facilities of its kind in the UK.
Before he set off on his 13 hour and 21-mile swim, Wolf said “The bio-fixing which we are working towards will allow children to have one-off operations with their own stem cells so they will not have to have repeated operations as they grow into adulthood.”
Cunicode’s new 3D printed art
Cunicode, a 3D printing art studio in Barcelona, Spain, has released a new collection of stoneware art called Permutation.
Each piece in the collection is composed of a random combination of nine basic units that are placed around a cylinder. These pieces were designed with Grasshopper 3D modeling software and 3D printed by on a PotterBot 3D printer.
One of the key selling points of these new pieces is that each one is unique and exists within an immense landscape of millions of possible different combinations. The 3D printed sculpture known as P16.4, contains over sixty-six quadrillion possible combinations.
Cunicode’s previous works includes other 3D printed artwork such as cups, busts, and figures designed after children’s drawings.
With the ability to 3D print penny-scale parts, the LulzBot Aerostruder v2 Micro tool head can be used with both flexible and rigid filament for precise and miniature parts. The expanded functionality of this tool head intends to give engineers and designers a higher level of detail and surface quality within their 3D printed parts.
“The Aerostruder v2 Micro Tool Head—paired with the LulzBot Mini 2 3D Printer—has changed my perception of what is possible with filament 3D printing,” explains Adam Straight, Product Specialist at Aleph Objects.
“In terms of resolution and surface finish, the prints from this new tool head are very impressive.”
An integral component in the production of high-precision, miniature 3D printed parts, the Titan Aero features a 0.25mm nozzle and a 360-degree part cooling fan which improves overhang and bridge performance. Straight added, “The precision of E3D Titan Aero extruders and hot ends complements the premium quality built into every LulzBot 3D Printer.”
Now in its second year, the partnership between Aleph Objects and E3D was formed due to the companies’ shared focus on developing open source hardware for 3D printers. “Free, Libre, and Open Source development respects user freedom drives better products, accelerates innovation, and strengthens user communities,” stated Harris Kenny, President of Aleph Objects.
Sanjay Mortimer, Co-Founder and Director of Research and Development at E3D Online, added, “Aleph Objects probably [has]the most useful and interesting array of tool heads for their 3D printers, and E3D is excited to contribute its expertise to a tool head that really pushes the limits of the technology,”
“It’s a lot of fun collaborating with a like-minded company that also trusts their users to really engage openly and freely with the technology. There’s a lot more to come from this collaboration, and we feel like we’re just getting started.”
Every quarter, the 3D Printing Industry Index will be compiled and published. The index is constructed using a survey of leading enterprises in the 3D printing industry. It is intended to be a measure regarding past, present and future sentiment towards several key metrics from the perspective of industry leaders.
In coming months, our survey results for the current quarter end of June 30 will be joined by corresponding data points for future quarter end dates. This will allow analysis of trends in the 3D printing industry to be conducted.
What is a sentiment index?
Sentiment indexes are powerful and widely used macro-economic tools. Central bankers, economists, financial analysts, VCs, investors, financial managers and journalists use them for forecasting, trend analysis and generally to gain insights.
Our approach with the 3D Printing Industry Index is similar.
The data for our index is collected by surveying a representative sample of the additive manufacturing ecosystem on a quarterly basis.
As a global industry, enterprises from across the world are represented. These range from operations with fewer than 10 employees to much larger enterprises. Hardware manufacturers, 3D printing material producers, 3D scanning companies, resellers, bureaus and the other enterprises that comprise the 3D printing industry are all represented.
This panel will be reviewed and updated as necessary to ensure the Index is a valid representation of the industry.
We will publish highlights and insights from the 3D Printing Industry Index for readers. Companies who participate in the panel survey will have access to a wider dataset.
Methodology for the 3D Printing Industry Index
The 3D Printing Industry Index is based upon the responses to a 5 question survey.
The questions address trading activity for the past and coming quarter, past and future hiring plans and changes to the gross margin. The full questions are as follows.
1. How was trading activity at your company during the past 3 months?
2. How do you expect trading activity to be during the coming 3 months?
3. Has your company expanded its 3D printing workforce in the last 3 months?
4. Does your company intend to expand its 3D printing workforce in the next 3 months?
5. How do you expect gross margin to change in the next 3 months?
There are 3 parts to the Index, the Global, Present and Future.
From the responses to the survey the index is calculated as follows.
Global Index: S = (n+ – n-)/(n+ + n- + no)
n+ the number of positive answers, n− the number of negative answers and n0 the number of neutral answers.
We also calculate the Present Index from the answers to questions 1 and 3, and the Future 3DPI Sentiment Index from the answers to questions 2, 4 and 5.
The resulting value of the Index will range between -1 and 1. A negative figure indicates that a majority of the panelists are pessimistic. While a positive value indicates that a majority of the panelists are optimistic. The closer the value is to 1 indicates just how positive sentiment is among the panelists.
We intend to publish the 3D Printing Industry Sentiment Index quarterly in July, October, January and April. Once several quarters worth of data is collected trend analysis will be possible.
Results of the June 2018 3D Printing Industry Sentiment Index
For the quarter ending the 30th of June 2018, the Global 3D Printing Industry Sentiment Index is 0.69. This value indicates a strong optimism among the panelists.
The value for the Present 3D Printing Industry Sentiment Index stands at 0.75. This demonstrates a healthy state for our sector. The Future 3D Printing Industry Sentiment Index is calculated at 0.65 for June 2018. This is a strong result. It bodes well for the sector in the months to come.
While the graph below only contains data for June 2018, in coming quarters it will be used to track trends in the 3D printing industry.
The iFix Pen, a hand-held co-axial 3D printer, extrudes bioink directly onto an eye to aid in the regeneration of cells on corneal ulcers. The pen also creates a biological barrier towards ongoing cornea damage caused by infections.
Brad Hazzard, the New South Wales Minister for Health and Medical Research, announced the recipients of the MDF, last Wednesday at the Parliament House in Sydney, Australia.
“Since the Medical Devices Fund began in 2013, the NSW Government has awarded more than $50 million in grants to 31 technologies,” said Hazzard.
“We are committed to supporting innovators in the medtech industry in getting their brilliant ideas off the ground and ultimately saving millions of lives around the world.”
The iFix Pen project
The iFix Pen Project is led by Gerard Sutton, ophthalmologist and Professor of Corneal and Refractive Surgery at the Sydney Eye Hospital, University of Sydney and Professor Gordon Wallace, Founder and Director of the Intelligent Polymer Research Institute, University of Wollongong (UOW).
According to the Save Sight Institute, corneal ulceration, a painful open sore on the clear front surface of the eye which can lead to blindness, is a common problem in Australia and developing countries. Approximately 55,000 Australians with corneal ulceration present themselves to hospitals for treatment each year.
Thus, Professor Sutton and Professor Wallace began developing the iFix Pen Project as an alternative treatment that will potentially reduce the number of patients afflicted with corneal ulceration. The team’s research, which was first reported in the journal Biofabricationin 2016, has shown that the iFix Pen can accelerate feeling, minimize pain and reduce patient recovery time, through the deployment of antibiotics.
The project also collaborates with Professor Peter Choong, Sir Hugh Devine Chair of Surgery, and Head of Department of Surgery at the University of Melbourne, and the NSW Organ and Tissue Donation Service.
“Winning the Big Idea last year gave us two things,” Professor Sutton says. “It gave us credibility when we were applying for other grants and the self-belief that we had a great idea worth developing.
“The iFix pen is one part of an overall corneal bioengineering project and, with the support from The Big Idea and the Medical Devices Fund, we are also hoping that within the next five to 10 years, we will be able to develop a 3D bioengineered cornea.

Independent research and technology organisation TWI, also known as The Welding Institute, has announced that it will lead the Open Architecture Additive Manufacturing (OAAM) project. With the contribution of several regional research institutions and global organizations, OAAM is an initiative set to provide the UK aerospace sector with large scale metal 3D printed components.
The government’s Technology Strategy Board Innovate UK is funding the program, and has so far granted contributors over £6.5 million ($8.27 million approx.).
The OAAM program focuses on the development of large-scale directed energy deposition (DED) additive manufacturing, a technique commercially marketed by companies including Formalloy, Optomec and AddUp. The abstract suggests that multiple DED based technologies will be developed throughout the duration of the project, advancing the current capabilities of arc-wire/laser-wire at Cranfield University, and TWI’s electron beam wire and laser-powder/laser-wire processes. Cranfield’s wire arc additive manufacturing (WAAM) method in particular has already proven an ability to create potentially record-breaking large-scale metal parts.
Funding from Innovate UK has been shared out between each body with TWI receiving the lion’s share of $2 million. With an estimated project cost of $1.7 million, Cranfield University was granted 100% of the proposed from Innovate UK. Further numerations are detailed below.
Scaleable, integrated, metal additive manufacturing
The various technologies developed through the project are required to be scaleable; work with common CAD/CAM interfacing; and integrate four traditionally isolated steps of production: non-destructive testing (NDT), machining, inspection and cold-work. Necessarily, the technologies must also conform to aerospace level standards.
Innovate UK’s funding period for OAAM has been initially set to run until December 2020. The goal over the next two-three years it to develop the technologies to Technology Readiness Level (TRL) 6, i.e. a functioning demonstration of the method’s capabilities, or Manufacturing Capability Readiness Level (MCRL) 4/5, “Capability to produce the technology in a laboratory environment” or “Capability to produce prototype components in a production relevant environment.” Following this, OAAM technologies will have to pass through three further TRLs or 5/6 MCRLs before they are considered the “highest level of production readiness,” and fully validated for a commercial market.
Designed to produce realistic prototypes, this consumer-oriented 3D printer uses Color Jet Printing (CJP) technology, which combines inkjet printing with the fused filament fabrication (FFF), to create a range of colorful prints that allow designers to vividly envision their final product without having to paint it.
“Desktop full-color 3D printing is here,” said Simon Shen, CEO of XYZprinting. “Now, consumers can purchase an easy-to-operate, affordable, compact full-color 3D printer for $30,000 less than market rate.”
“This is revolutionary because we are giving the public access to technology that was once only available to industry professionals.”
Color 3D printing for a lower price tag
XYZprinting, launched the da Vinci Color Mini’s predecessor, the da Vinci Color 3D printer, in 2016 Now, with STEM students, film model makers, and toymakers in mind, XYZprinting have created a smaller, more convenient, user-friendly 3D printer.
The da Vinci Color mini includes a hands-free auto calibration, an EZ removable print bed, WiFi connectivity, and a 5-inch color LCD screen. Its “full-color” 3D printing abilities reportedly provides over 15 million color combinations from new 3-in-1 CMY ink cartridges. Using its 3DColorJet technology, the da Vinci Color mini mixes and spreads droplets of colored ink from printer ink cartridges between designated layers of PLA, creating a multi-colored 3D printed model.
An upgradable laser engraving function for wood, leather, and more materials and mono-color 3D printing in PLA, PETG, and Tough PLA have also been added to the printer.
With lighter hardware and automated settings, XYZprinting believe that the da Vinci Color mini is best suited for “small business owners seeking cost-effective solutions or starting their own full 3D printing businesses; educators interested in incorporating full color 3D printing into classrooms and curriculums; fans and collectors who love geek culture; and day-to-day consumers.”
Technical specifications and Pricing

The da Vinci Color mini retails for a price of $1599.95. Early adopters of XYZprinting’sIndiegogo campaign can pre-order the da Vinci Color printer for $999.95. The 3D printer is set to ship to backers in October.
XYZprinting’s da Vinci Color mini will also be on display at IFA 2018, August 31 – September 5, at the Berlin Exhibition Grounds, in Berlin, Germany.
Hobbyist and Reddit 3D printing community contributor Marioarm has built an “almost fully” 3D printed CNC machine for milling electronic chipboards.
Marioarm built the Cyclone PCB CNC machine with 3D printed parts downloaded from file sharing sites such as Thingiverse and the GitHub repository Cyclone PCB Factory. With minimal, prefabricated parts, the project in total cost Marioarm under $200 to build.
The Cyclone CNC machine
Marioarm’s machine is a combination of 3D printed and non-3D printed parts. Non-3D printed parts include precision sliders for controlling the drill, a solid wood base, three stepper motors, cables, power supply, drill bits, screws, a CNC controller, and a rotary tool.
The rest of the parts including, holders, frame, gears for axis etc., were 3D printed. The cost breakdown is as follows:
– CNC controller: $5-6
– a rotary tool: $50
– three Nema Stepper Motors (17HS3401): $30-36
– 5 steel rods: $25-30
– a rubber hose for vacuum: $3
– drill bits: 10 pieces cost $3
The cost of these parts adds up to $126. Adding $50-$70 for the cost of minor bits and pieces, and 3D printed parts, the total amount reaches only $176-$196. The original Cyclone design had problems with backlash and wobbling, but Marioarm solved the problem by replacing threaded rods with lead screws and adding spring tensioners. According to the creator, the machine is specifically designed to mill Printed Circuit Boards (PCBs) for surface-mounting.
Open source 3D printing and the maker movement
The open source culture of 3D printing has provided hobbyists with cost-efficient alternatives to many problems and develop their ideas. In Marioarm’s case, some of the shortcomings of the original open source Cyclone PCB machine were overcome by making minor modifications.
In recent years, open source culture has had a significant impact onhumanitarian aid projects. In 2016,Mohammed Abu Mattar, a Glia project member working in Gaza, circumvented a ban on 3D printer imposed by the Israeli government. He made a 3D printer using spare parts and open source designs. Theopen source 3D printer was used to make medical hardware which is otherwise expensive and unavailable in war zones.
Despite Cody Wilson’s assertions, the debate over 3D printed guns is not over yet. Last week, social media giant Facebook became the latest organization to weigh-in on the discussion in an update to its Community Guidelines.
According to numerous sources, Facebook released a statement saying: “Sharing instructions on how to print firearms using 3D printers is not allowed under our Community Standards,”
“In line with our policies, we are removing this content from Facebook.”
The so-called age of the downloadable gun
Though 3D printed guns remain a critically impractical and convoluted way of obtaining weapons, as one of the most “hot topics” of 3D printing, in the public eye at least, we have been closely monitoring the rise of the “3D Downloadable Gun”.
The idea was first conceived in 2012/2013 when crypto-anarchist and gun-rights activist Cody Wilson designed and began the digital distribution of files to make the Plastic Liberator handgun.
In the weeks following this decision made by the Department of Justice, Wilson’s site for sharing the files (Defense Distributed) was taken offline by an order from a federal judge in Washington, and the issue has served to inflame further discussion over the general terms of gun control in the United States.
However, since the files were shared by Wilson, they have remained online through sources outside of Defense Distributed.
Facebook prohibits downloadable guns
Sites known to contain files for 3D printing the Plastic Liberator and semi-automatic firearms, have now been prohibited by Facebook.
Sharing such links and files fall under the site’s Regulated Goods Policy that prohibits “the purchase, sale, gifting, exchange and transfer of firearms, including firearm parts or ammunition, between private individuals on Facebook.”
The policy affects all posts made to Facebook news feed, friend timelines, private messenger exchanges and Instagram, with any attempt automatically flagging as spam.
In response to the move, the Firearms Policy Coalition has created a call to action asking Facebook to lift the ban on one affected site, CodeIsFreeSpeech.com that advocates: “Information is code. Code is free speech. Free speech is freedom.”
According Buzzfeed, a Facebook spokesperson has said “the company is currently working on scaling up its anti–3D gun policy.”
