Live Demonstration of ACES Concrete 3D Printing Technology at CERL to 3D Print Barracks: Part 3

As part of a three-year program called Automated Construction of Expeditionary Structures (ACES), last year the US Army 3D printed a complete barracks, also known as a B-Hut, out of a patented concrete mixture. The program is researching 3D printing as a way to build semi-permanent structures out of concrete, made from locally available materials – the goal is to reduce the amount of building materials that need to be shipped out by half, and decrease construction manpower requirements by 62%, when compared to expedient plywood construction.

Last week I was invited out to the Engineer Research and Development Center’s Construction Engineering Research Laboratory (CERL) in Champaign, Illinois for a live demonstration of the ACES technology…an invitation I was happy to accept. Last year’s B-hut took 21.5 hours to print, but that’s the total number of print hours, and wasn’t continuous. This time, the ACES team, with assistance from its project partner – Chicago-based architectural and engineering firm Skidmore, Owings, and Merrill (SOM) – and Marines from the 1st Marine Expeditionary Force, was going to attempt something new.

The ambitious plan was to complete the two halves of another barracks structure, completely out in the open and not covered by a tent, in 24 hours of continuous 3D printing. What moves the demonstration from ambitious to brave was the team’s decision to invite journalists to see the live print, and I’m not just talking about myself – I saw cameramen and reporters onsite from at least two different local TV stations.

The Marines were briefed on the specifics of the technology ahead of time, and ran the equipment themselves this week, as they will be the ones actually 3D printing the structures in the future if the program is successful. However, the ACES team and SOM were onsite in case they needed to offer any assistance, and that assistance was needed a time or two during the live demonstration.



Program manager Michael Case, PhD, told me that an issue with concrete is evaporation drying, so when the forecast showed rain, the start time was moved up a few hours, only to halt again pretty quickly once the team realized that they needed a new pump – the interior of the original one had been torn up by the sharper materials used during a live demonstration at Fort Leonard Wood a few months ago. Then the kinks needed to be worked out of the hose, and when the material didn’t extrude properly after the print began, the team removed the nozzle and discovered that a rock was inside messing up the flow.

The material mixture had to be adjusted after the first layer because it was too sloppy, at one point the nozzle was accidentally sent over to the side that wasn’t being worked on yet, and when steel dowels were added for initial reinforcement to the first several layers of 3D printed concrete, work began on the wrong side. But in spite of these minor setbacks, work continued through the night and Public Affairs Specialist Mike Jazdyk told me that there were very few clogs.

On the morning of the second day of printing, Jazdyk told me that the ACES team would not make its original goal of a continuous, 24 hour 3D printed concrete barracks. A lot of this was due to concrete curing inside of the pump, which caused the equipment to shut down and cause some overnight delays. By the time I had to head for home, the team had nearly completed the first half of the structure and was planning to take several hours of much-needed rest before starting in on the second half. Jazdyk informed me that work would begin again around midnight.

I received a call from Jazdyk on Friday afternoon, and he told me that the ACES team had to stop the print due to equipment failure, but that they had managed to complete roughly 80% of the structure before this happened – this is easy to see in the image below.

“What you see is 40 hours of printing,” Jazdyk told me about these four photos he sent, noting that this number does not denote a continuous job, but rather is the total number of print hours.

Jazdyk explained that had the equipment not failed, the ACES team at CERL would have finished the structure in less than 48 hours, which is still an extremely impressive feat. As previously mentioned, the fact that the team was willing to have the press onsite for the live demonstration, without knowing for certain if they would make their goal, was valiant.

A closer look at a completed section.So often with 3D printed construction projects, we are assaulted with people and companies saying, “Look, I’m the first!” or “I did it the fastest!” or “I built the biggest thing in the world!” At CERL this week, everyone I spoke to was very candid with the issues the project was running into, and no one tried to pull the wool over my eyes or move me away if something went awry. People answered every question I asked openly and honestly, even if it was a question relating to something that was currently going wrong – this is admirable.

“No one shows you under the skirts of large-scale concrete 3D printing – all you see are the videos that are posted online of just what people want you to see, and nothing else,” project manager Megan Kreiger told me. “You don’t see all the problems that you have to overcome. They make it look like they’re doing it super fast, super easy, and that they’re doing it under 24 hours, but none of it’s true.”

Team members also shared their hopes for the program with me, like ultimately lowering the cost of materials and the amount of manpower needed, and the potential applications the ACES technology could eventually be used for other than 3D printing buildings, such as culverts, barriers, and bridges, and more humanitarian efforts, like schools.

“There’s a tremendous number of uses,” Dr. Case told me.


Jazdyk told me today that they will attempt to complete the 3D printed concrete structure next week at CERL. I am confident that they will succeed, but, knocking on wood and knowing that sometimes things just go wrong, I am also confident that should more problems arise, the ACES team will handle them with grace, learn from them, and keep on trucking.

Stay tuned to 3DPrint.com for more news about my recent visit to CERL, including plenty of information that I did not previously know about concrete and the importance of the shape of these 3D printed walls.

3D Printing News Briefs: August 3, 2018

On today’s 3D Printing News Briefs, we’re giving you the rundown on some of the latest 3D printing stories to get you into the weekend. Sintratec has welcomed a new distribution partner in South Korea, and CRP USA will be attending the upcoming SmallSat conference in Utah. A small 3D printed chain link was used to lift a really big load, Desktop Metal published a video on how to debind parts for sintering, and the US Air Force is setting up a rapid sustainment office, which will use modern technologies like 3D printing to lower the costs for aircraft repair. Finally, Cimquest explains some of the most fundamental concepts of 3D printing.

Sintratec Welcomes New Distribution Partner

Junwhan Lim, L.corporation CEO, and Christian von Burg, Sintratec CTO

Top Swiss 3D printer manufacturer Sintratec is ramping up its efforts in South Korea, and has now announced L.corporation as its new distribution partner in the country. The Seongnam-based 3D printing specialist has several years of experience in distributing SLA and FDM 3D printers from other manufacturers. Now, with the addition of the Sintratec Kit and Sintratec S1, L.corporation can add SLS 3D printers to its portfolio.

“The SLS market in South Korea is still underdeveloped compared to the FDM and SLA markets,” said Junwhan Lim, the CEO of L.corporation. “In the industrial sector, the SLS market is dominated by EOS. However, the demand for 3D printers in the Korean industry is still below its potential as the necessary skills are lacking. Sintratec’s entry-level models are exactly what they need.”

CRP USA to Attend SmallSat Conference

The annual Small Satellite (SmallSat) Conference and exhibition starts tomorrow, August 4th, at Utah State University, and CRP USA will be attending the event for the fourth year running. The company will be displaying its innovative space industry solutions, obviously, 3D printed with its high-performance Windform materials family. One of these is a 3D printed CubeSat, designed as both a sole CubeSat and a unique way to dispense two smaller TubeSats.

At its booth #43T at SmallSat 2018, CRP USA will be demonstrating how effective Windform 3D printing materials can be for creating structural space applications such as smallsats, as these composite materials have passed outgassing tests. The SmallSat Conference will be held at the university’s Taggart Student Center until August 9th.

HK3D Solutions 3D Prints Strong Tractor Part

When we hear about strong 3D printed parts, the obvious question to ask is “Just how strong is it?” When HP launched its Multi Jet Fusion 3D printing technology back in 2016, the company provided an obvious example of the strength of its materials by 3D printing a chain link, which was then used to lift a 1995 Toyota Avalon into the air. Some of the most high-strength materials out there are made of carbon fiber by Carbon and Markforged.

Recently, HK3D Solutions, which is home to the first Markforged print farm in the UK, performed a similar test of strength, and 3D printed a 77-gram chain link with Onyx carbon fiber filament by Markforged. This 3D printed part had lifted 1,102 lbs before, but the company wanted to test it in a real world scenario. So the engineers took the part to an actual farm and attached it to a tractor, then used it to successfully lift and carry 2,645 lbs of manure.

Tractor Uses 3D-Printed Part to Haul 2,600 Pounds

Desktop Metal Debinding Parts

In a new video, materials engineer Jesse Cataldo from Desktop Metal shows viewers exactly how easy it is to debind a part 3D printed in metal on the company’s Studio System. It’s important to debind your metal parts, as it gets them ready for sintering. The process begins in the Fabricate dashboard, when you select the parts you want to debind, set up a new job, and choose your debinder.

Once both lids of the debinder are opened, you can put your parts inside and close and lock the lids back up again. Choose the Jobs in Queue from the debinder’s user interface screen, select your job, and hit the Start button. The cycle should take about 15 hours, after which you have fully debound and dry parts.

Air Force Rapid Sustainment Office

Air Force Secretary Heather Wilson demonstrates a 3D printed part of a KC-135.

According to USAF secretary Heather Wilson, in the first quarter of 2017 alone, the US Air Force had 10,000 requests for parts that did not receive a bidder, either because the original manufacturer was no longer in business or because it was not feasible for an existing company to make just one part. In order to use emerging technologies like 3D printing and robotics to reduce the cost of operating depots and fixing aircraft, the USAF will be creating a new rapid sustainment office. Wilson said at a recent Washington Post event that this office will create new ways to use technology, including cold spray to repair metals and using 3D printing and robotics to make depots more efficient by creating replacement parts.

“We reverse-engineered this and 3D printed it,” Wilson said at the event in reference to a 3D printed “trim wheel” for a KC-135 tanker. 

“This part cost about $50, $55, including all the engineering and everything else. If I had to go out to industry and have them set up the traditional way to do it and buy one part, this is over $700. So we can drive down the costs for a part that is airworthy.”

Cimquest Explains Key Concepts Behind 3D Printing

CAD/CAM integrator Cimquest, a 3D printer reseller for Rize, Stratasys, and HP, wants to make sure that the world knows about and understands the most important and fundamental concepts of 3D printing – accuracy, precision, and tolerance.

Dave Macfie, the company’s Director of 3D Printer Sales, is the star of the new video in Cimquest’s “2 Minute Tuesday” series, which explains why it’s important to understand these important concepts, and the differences between them, in order to get your desired level of 3D printing performance. In the video, Macfie provides detailed descriptions of these three concepts and why they are important. Check out the full video below:

How to Turn a 2D design into a 3D print in three simple steps

Here at Shapeways, we believe everyone has the potential to create something amazing; all you need are the right tools and support to bring your ideas to life. That’s why we’re so passionate about making 3D printing more accessible with easy-to-use 3D modeling tools and apps. One of our favorites is our 2D-to-3D app, which converts images and drawings into fully fledged, printer-ready 3D models. So if you’re new to 3D modeling or simply want to mock up a new design quickly, keep reading for our expert guide on how to go from 2D to 3D with ease!

Upload buttonStep one: Upload Your Image
After opening the 2D-to-3D creator, the first step is to upload your design. You can upload anything from found illustrations to patterns and shapes. Tip #1: If you are making a drawing, black and white works best where the black is the outline of your design and the white represents the empty space. We also recommend using thick lines so your product can be printed in a greater variety of materials (minimum wall thickness for materials vary from 0.3 mm to 3.0 mm). Tip #2: If you are printing a word or a phrase, make sure the edges of the letters and characters are touching, so you can print in one piece instead of multiple ones. 

Customize button
Step two: Customize Your Design
Now that your design is in the creator, it’s time to adjust its size to your taste and needs. On the app, there are sliding scales and backing options that allow you to play with the design’s customizations. You can set your object to be as small as 5 millimeters or go all the way up to 100 millimeters. We suggest working with a ruler on hand in order to help you tangibly visualize sizes. You can also add one of two loop designs to make this a keychain, or choose “none” if you prefer to keep the design as is.

Print button
Step three: Print Your Original Design
Once you’re happy with your creation, it’s time to send it to our printers. Simply hit “Create My Keychain” to convert this into a 3D modeling file, then click on “View Model” to proceed to the next page where your model will be automatically checked to ensure printability in a range of materials suitable for your model size. If this is one of your first 3D printed products, we suggest using our Versatile Plastic, which is great for prototyping. Once you’ve selected your desired material and finish, follow the checkout page to complete the process. It’s really that easy!

Now it’s time for you to take what you’ve learned and actually create something. Test out your new skills by uploading a 2D design into our custom creator. Happy making!
