North Carolina knows rapid prototyping and 3D printing. N.C. State University, Duke University, UNC Chapel Hill and the Research Triangle Park anchor the Raleigh-Durham-Chapel Hill area, making the region a hotbed of rapid prototyping on the East Coast. The Tar Heel State also has (as of February 2017) more than 326 3D Hubs within its borders and 3D-printing work labs spread throughout the campuses of its post-secondary schools. To get to know 3D printing in North Carolina, start with the innovators and look to the area’s large amount of colleges and universities.
Chapel Hill’s altruistic star shined bright in 2014, when UNC biomedical engineering major Jeff Phillips created a prosthetic hand for a local 7-year-old born using a 3D printer and 3D printer filament from UNC’s biomedical engineering lab. At a cost of about $20 for the filaments, the prosthetic allowed the child to grasp objects for the first time, and contributed to advancement in the field of prosthetics.
Aly Khalifa, TEDxer and cofounder of Raleigh-based Designbox, approached leather shoes’ resistance to biodegradability by starting LYF shoes, which makes modular footwear without adhesives. LYF shoes not only break down easier than leather shoes, you can repair them or print new uppers and soles, which consist of an insole, performance plate, heel lock and sole, using a 3D printer.
Author and entrepreneur Ping Fu and 3D printing go way back — all the way to 1997 when she co-founded 3D software firm, Geomagic — and she hasn’t stopped since, now serving as 3D Systems‘ Chief Strategy Officer in the Research Triangle Park. 3D Systems produces the Figure 4 printer, which prints 50 times faster than conventional SLA 3D printing systems and puts out about four billion drops of 3D printing filament per minute.

Printing with flexible filament can be a delicate balancing act. To achieve great results, your printer needs to be a finely tuned machine along with using a good high quality filament and perfecting the settings in your slicing software. Here are five things to consider when printing flexible material. Remember, changing any of these can drastically change the print.
1. Print Speed
|Due to the nature of flexible TPU filament and the potential to kink or buckle when being pushed through the hot end, it is highly recommended that you hit the brakes on your print speeds and slow them w-a-y down. Typical print speeds for non-flexible filaments can range from 30mm/second all the way up to 90mm/second. For flexible, slower is better so we recommended starting around 30mm-40mm/second and see what works best in your particular printer.|
2. Proper Extruder Setup
|A direct drive extruder will work best when trying to print flexible TPU. However, you can print flexible on a Bowden-type extruder but with some increased difficulty. We are currently working on flexible extruder adapters that will allow you to print TPU easier on a printer with a Bowden-type extruder. If your printer is not equipped with a Bowden tube, then adding one to help guide the filament can give you a better chance of avoiding filament buckling.|
3. Print Temperature
|Flexible TPU is especially sensitive when it comes to the temperature of your hot end. We recommend that with our material you start at 220°-245°C and fine-tune your settings for the best results. This will reduce the oozing material from the print head that can create messy or stringy prints.|
|Your retraction settings will also play a big part in getting good results and avoiding stringy prints. Retraction is when the extruder motor moves in reverse ever so slightly to avoid extrusion when moving across a gap in a printed design. Too little retraction and you will be left with cobwebs of material all over your print. Too much retraction will leave you with blobs of filament when the print head starts its next segment of printing.|
5. Bed Adhesion
|Proper bed adhesion is key to any successful print but with flexible TPU, it is even more crucial. We recommend that you only try printing flexible on a printer with a heated bed with the temperature range set between 45°-60°C. Check out our article on bed preparation for more information.|
ABS and PLA filaments are widely known in the 3D printing universe, but there are important advantages of PETG filament in 3D printing that are causing it to quickly growing as a popular option for builds. The properties of PETG make it an appropriate choice for producing a vast array of impact-resistant and flexible items.
PETG is a modified form of polyethylene terephthalate (PET), a thermoplastic widely used in plastic bottles. In fact, 43 percent of U.S. soft drinks are delivered in PET bottles.
Glycol-modified PET (PETG) is an increasingly popular filament material because it’s more durable than common alternatives. The addition of glycol prevents crystallization so it won’t become brittle when heated. PETG is a highly transparent co-polyester that can be dyed as required. It is possible to produce brightly colored, translucent prints with a nice, glossy finish with minimal post processing.
As the 3D printing industry matured, PETG emerged as a viable and attractive alternative to ABS and PLA. Here are some of the qualities that drive interest in this advanced filament material:
- Excellent layer adhesion
- Warp resistance
- Reduced shrinkage
- Higher density
- Chemical resistance to both acidic and alkali compounds
- Flexible printing on glass, acrylic, glass, blue tape and polyimide tape
- Odorlessness during printing
Finished prints are pliable and more impact-resistant. In fact, PETG is flexible enough that it is virtually unbreakable in the layer direction. Excellent layer adhesion translates into improved surface finishes. Low shrinkage means it is often a good choice for printing larger items.
PETG is worth considering any time your 3D print needs to be tough, durable, flexible and impact-resistant. It is ideal for use in the production of a wide array of mechanical parts. The rapidly expanding robotics technology sector is also embracing PETG printing. The smooth finish of PETG prints, and the fact that the plastic is FDA-compliant, makes it an appropriate choice for printing creative and/or intricate kitchenware designs. You are really only limited by your imagination.
Enterprises looking for a filament that will produce translucent, shatter-resistant items like phone cases will also want to take a close look at using PETG filament.
PETG filament favorably compares to other popular 3D printing materials:
- PLA/PHA filament — Polylactic (PLA) is a biopolymer commonly derived from cornstarch and sugarcane. PETG print speeds are similar to those of PLA, although the melting point is higher. Like, PETG, PLA and PHA filaments are relatively easy to use. However, PETG is more dense (38g/cm3).
- ABS filament — Acrylonitrile-Butadiene Styrene (ABS) is temperature-resistant like PETG. While ABS is harder, PETG is more flexible and more durable. PETG is odorless during printing, while ABS emits a noticeable odor.
- TPU filament — Thermoplastic Polyurethane (TPU) is not as dense as PETG; the density of flexible TPU filament is just 1.21g/cm3. The chemical resistance of TPU is good, while the chemical resistance of PETG is excellent.
Once you do the math, you’ll see that PETG can be a high-quality, cost-effective alternative to these other filaments.
One of PETG’s virtues is that it is recyclable. It is different from many other plastics because its polymer chains are readily recovered for future use. PETG can be recycled for use as a gas barrier. Its chemical resistance makes it a good barrier when used with solvents and alcohol. Be sure to always check with your local recycler for their rules and regulations on what you can bring and what they can recycle.
We here at MakeShaper are excited to launch our line of PETG filaments. Available in two diameters and a dozen colors, our filaments provide superb extrusion every time, in every project.
We also offer a wide range of made-in-the-USA filaments in a spectrum of deep, saturated colors and full range of diameters and spool sizes. Crafted in Sanford, North Carolina, from high-purity raw materials, MakeShaper makes high quality performance filament so you can make anything!

Bed adhesion or 3D printer bed prep is one of many factors to consider when it comes to producing successful 3D prints. The first few layers are usually the most crucial as it can set the tone for the rest of the print. MakeShaper has a few suggestions on how to prep your bed prior to printing, but before we dive deeper – the first thing to consider is the orientation of the print itself when printed. Using supports may be a headache to remove, but a large footprint on the print bed could make even the first few layers susceptible to warping or other problems on certain materials.
MakeShaper usually recommends using glue on printers with a heated bed, depending on the filament material. To apply the glue, first start when the bed is cool to avoid the glue melting. A rule of thumb is you want to apply the patch of glue slightly bigger than the base of the printed part. We recommend using a water-based (PVA) standard glue stick. Our office favorite is the classic standard of Elmer’s water-based glue. Since not all materials have the same print characteristics, we recommend different methods for applying glue for different materials.
When printing with ABS, you should use two thin layers of glue. The first layer should be applied in the same direction and not overlap. The second layer should be applied over the first layer perpendicular to the direction of the first layer (think crosshatching or a lattice). This will help reduce the chances of warping when printing with ABS.
When printing with PLA, only use one thin layer of glue. Like preparing the bed for ABS, start by applying glue to a cool bed in the same direction and try to minimize overlap. PLA tends to not warp like ABS so it only needs one layer of glue for good bed adhesion.
When printing with PETG and TPU filament, we do not recommend that you use any kind of additional bed preparation such as glue for layer adhesion.
There are many factors when producing high-quality 3D prints. What we recommend may not work for every printer in every environment. Take our recommendations as a baseline and play around to figure out what will work best for your printer, material, design and environment.
MakeShaper is updating the way we label the diameter on our filament. Our 3.0 mm filament will now be labeled 2.85 mm. We’ve always manufactured our 3.0mm filament to a 2.85 mm specification, it’s just a change in the way we will label and refer to the product.
So… why did we call it 3 mm if it was 2.85 and why change it now?
Well, there are a lot of 3.0mm printers out there. That designation comes down to the size of their extruders and filament feeding tubes, which are exactly 3.0 mm (or the inner diameter is close to 3.0 mm). When using filament that is exactly 3.0 mm in a 3.0 mm printhead, expect some serious clogging issues, especially with a Bowden type extruder.
In the industry, most filaments labeled 3.0 mm are actually just slightly less in diameter to prevent this issue. We are extremely proud of our tight tolerances and are now updating our labels to match the true diameter of 2.85 mm. There are no changes to the actual filament.
A while back we were contacted by Mike Learned (who runs a successful YouTube channel called NeoPortnoy 3D Printing) to do a review of our PLA filament for us. We sent him a sampling of our products and through a bit of back and forth conversation, we got his printer optimized and printing our filament with successful results. Check out his video for more information on his thoughts and opinions of our products.

Printing with flexible filament can open up countless possibilities and opportunities for creative and functional manufacturing. Harnessing these capabilities does not come without effort.
However, MakeShaper, a filament manufacturer in Sanford, North Carolina, has cracked the code for a premium, FDA-compliant, flexible filament that is also easy to use.
“We were approached by a business experiencing problems implementing flexible 3D printing into their product development environment that was also FDA-compliant for a wearable device,” said Erica Edwards, the company’s sales manager. “They had specific needs and were not able to meet product expectations. They were experienced with FDM manufacturing and were already set up with their printers of choice. However, they were unsatisfied with the results they were achieving while testing the current offering of flexible filaments.”
Flexible filament has proven to be a tricky material for many. It is prone to issues related to feeding the filament through the printer. Even printer designs that overcome feed issues can oftentimes produce stringy, unusable prints depending on the specific properties of the filament in use.
The MakeShaper team got to work to develop a solution that could meet the needs of the client, focused around a newly formulated TPU flexible filament. Up until that point, MakeShaper was best known for being the only manufacturer to offer alternative cartridges for Cube2, CubePro and CubeX printers, along with their line of premium ABS and PLA filaments.
MakeShaper is a subsidiary of Static Control Components, the largest supplier and manufacturer for the 2D printing aftermarket industry. This connection gives the MakeShaper team a deep history of working within a market to develop timely solutions as well as access to Static Control’s expansive research and development facilities. MakeShaper engineers were eager to create a new, premium flexible filament.
“We assessed the situation and the market as a whole,” said Edwards. “We fine-tuned the material properties of our filament formulation and in the process, also upgraded the capabilities of the printers being used.”
“After it passed our quality standards, we knew we had something that should be shared with others who have struggled with flexible printing,” she said. “We want to bring what we have developed to a wider audience and are releasing TPU 85A flexible filaments.”
MakeShaper’s flexible filament offers some unique qualities unseen in other offerings. The filament is FDA-compliant for direct food contact, along with having Pantone-matched color selections. The colorants are UV-stable and colorfast, meaning the color will not fade from the end product over time.
The Shore Hardness of the filament is 85A – roughly the flexibility of shoe soles. The rubbery filament exhibits a slight sheen, meets exacting standards for consistent diameter/ovality and builds prints that are true to design.
Edwards also noted that the holistic approach to engineering a solution led to them developing a printer adaptor to help select printers to better utilize flexible filaments.
“We noticed that some printer manufacturers do not recommend using flexible filament because of the material buckling when the filament is pushed through a hot extruder,” said Edwards. “The adaptor modifies the filament feed mechanism and allows printers to easily use flexible filaments with no problems.”
After the adaptor was prototyped, MakeShaper reached out to numerous 3D printer manufacturers to discuss the opportunities an adaptor could provide. With the positive response, a wave of solutions will be released soon for multiple printers.
“This adaptor makes it easier to work with flexible filament and also works with the more common harder plastic filaments, such as ABS and PLA,” said Stephen Daniels, an engineer with MakeShaper. “Before the adaptor, threading flexible filament was like trying to push a rope up a hill in a pipe with no kinks. Not an easy task!”
The adaptor for Fusion F306 printers is currently available and adaptors for MakerBot Replicator/Replicator 2, Zortrax M200, Ultimaker 2+ and Cube2 will be released soon.
And as for the business that sparked the move into flexible filament?
“Ultimately, the business was able to use our flexible filament and get the quality builds they had initially expected,” said a pleased Edwards.
Flexible filament is available on 220g, 650g and 1kg spools in black and natural. Other colors will be released throughout the summer. Larger spools up to 30kg are available by special order.
“We are always open to working with a client to provide market solutions,” Edwards noted. “If you are seeking a filament manufacturing partner or just need some great filament – contact MakeShaper.”

A few weeks ago we had the pleasure of meeting Tom Meeks and showing him around our facilities, Tom wears many hats but one of them is technology and blogging. Tom has been a fan of Cube® printers and runs the blog http://cubifyfans.blogspot.com/ , along with that Tom is heavly involved with The YouthQuest Foundation which supports the academic, vocational and life-enriching development of America’s at-risk youth. If you want to read Tom’s account you can find it below or on his blog http://cubifyfans.blogspot.com/2016/06/visiting-makeshaper-and-witnessing.html#comment-form
Visiting MakeShaper and Witnessing Resilience Firsthand
A Tour to RememberWhile I can’t discuss all the steps that I saw being taken to produce the highest quality product, I can say that they even go so far as to build their own proprietary machinery if that is what it takes to better their peers. MakeShaper is a division of Static Control Components, which began in a garage about 30 years ago. They sure have come a long way since then. The facility, which creates 2D printer cartridges as well as the 3D filament that are of interest to us is absolutely massive! Touring the facility is not only enlightening, it’s exhausting for an old guy. But, it was well worth it.Resilience and Perseverance on a Grand Scale And, speaking of old guys, one of the most impressive aspects of the tour came in the form of a piece of art and a photograph memorializing a day that could have been the end of Static Control Components (SCC). In April of 2011 multiple tornadoes touched down in Sanford and decimated SCC’s facilities. The founder of SCC was 75 at the time and the damage was so severe that many though he simply might walk away. But, he did not. They were contacting customers and shipping product in days. Please read this story and view the images of the devastation. Here is a link to a news video that is well worth visiting if you want to understand the company’s character.
MakeShaper for 1st and 2nd Gen Cube & CubePro – More to come
The Makeshaper division is relatively young when compared to the age of parent organization. So, their product line is still growing. We saw 3D printers of virtually every make and model being used to develop and test new products. The current filament choices available for the 1st and 2nd Cube and CubePro are limited to Red, Green, Blue, Black & White in PLA and ABS. But, I expect that more choices will be forthcoming after extensive testing.
More than Just Filament
Joining me on this visit was Jeff Epps of the Richmond County school system just miles from MakeShaper’s headquarters. A good deal of the time of the visit was devoted to talking about how 3D design and printing can literally change lives of at-risk students. Both of us came away impressed by what we heard from MakeShaper’s management.
They ‘get it’.
So, I don’t expect that this meeting will be the last time we meet together to talk about our common goals in the communities in which we serve.
Bottom Line for 1st and 2nd Gen Cube & CubePro Owners.
The reason why I made the trip was to see if I could find evidence as to the steps MakeShaper was taking to ensure that we could trust their products in our printers. I came away feeling that they are striving to be the manufacturer of THE most reliable filament available.
The comprehensive testing is there. In fact, the level of testing is so much higher than the industry norm that I cannot even write about it in detail.
The construction is there. Every cartridge contains a bag of moisture protection INSIDEthe cartridge for continuous protection. The moisture protection bags are much heavier for additional storage protection.
The price is there. Currently a 2nd Gen Cartridge is just $25 with free shipping for orders over $50.
So, I would urge you to consider trying MakeShaper. And, let me know what you think. After all, the real testing is in YOUR hands. Only you can attest that the MakeShaper alternative is right for Cube owners. But, I trust you will find my assessment to match your own.
Let me know….
