It’s dino time! Recently Marcos Pérez contacted us and showed us an amazing project he has been working on: a brachiosaurus skeleton entirely made with our PLA/PHA Natural:

If the skeleton itself or the excellent print quality doesn’t impress you already, the size will. It measures 1.5 by 2.3 meters, weighs a whopping 7kg and consists of 23 pieces. The reason Marcos printed the brachiosaurus model is quite original – and awesome: “The model can be assembled and disassembled, and will be used in a children’s shelter, where the kids will search for the parts and then assemble it with some tools.”

And we thought it was merely a very cool print…

Originally the brachiosaurus roamed the plains of what is now North America. In real life, back before their demise about 66 million years ago, the brachiosaurus measured about 18 – 21 meters in length (head to tail), making this an approximate 1:10 scale model.


The story behind the brachiosaurus print

It all started with an order made by a Catalan company that is dedicated to creating themed hostels. One of them, which is dedicated to archeology, has a large area with sand. The idea was to make a large dinosaur skeleton (in terms of 3d printing) and several fossil replicas so that the children could accomplish archaeological work with their brushes and other tools. Marcos was advised by the Asturian company Geolag, with extensive experience in geology and archaeology ,that proposed me a series of models to replicate. One of those was the brachiosaurus: A dinosaur that, due to its large size, already represented a huge challenge.

He found a model, but it needed some rework. The file format had to be converted to multiple stl files, corrected and modified in Fusion 360 and later in Meshmixer before being sent to the Simplify3D slicer.

One of the biggest challenges was that the skeleton had to be mountable and removable, even by children. Therefore, it should have a simple mounting system and also be strong enough.

Printing all the parts wasn’t easy. Says Marcos: “The printing process was really tough. I needed a very large number of supports, considering that absolutely all the pieces had overhangs, some of them truly complex. With Simplify3d support system and filament’s pretty finish there was actually little post-processing. Just a slightly sanding and not much more.”

To give you an idea of the scale of this dinosaur print, here is the entire print in the garage:

Let this sink in: 2.3 x 1.5 meters and 7kg of filament…

Marcos continues to explain the printing proces: “For all this I used two Ultimaker 2+, and a pair of Creality cr-10s pro and cr-10s. I used 0’8 and 0’6 nozzles for most of the printings. And 0.2 to 0.24 layer height in some parts. This was not a problem again, due to the beautiful finish of the filament. In order to join the pieces, I made some pla stud, printed horizontally by a large nozzle. I drilled joint areas and fixed them with silicone. Being printed horizontally with a large nozzle, the ribbed surface that was formed in the studs helped me to keep the pieces in place. It was easier than I had thought. Because at first I thought of steel rods, but it was quite dangerous for children. For the very heavy cervical spine joints, and the ribs joints, I designed and printed much thicker curved studs.”

The printing process took about 450 hours!

Marcos started 3D printing about 10 years ago and has been acquiring prints ever since and, he explains “researching to be able to offer products to companies in this northern region of Spain, Asturias, mostly dedicated to the manufacture of steel. I have worked making molds for impellers manufacturing in smart lighting companies and others companies that need any type of pieces, always finished products and rarely prototypes and medium production runs. I also make artistic pieces and specific orders such as dinosaurs.”

He also sometimes teaches 3D printing classes and is very passionate about this technology, as we can see! Marcos always tries to convince business people how they can save on costs by using 3D methods.


We thank Marcos for sharing his very cool brachiosaurus project. Keep up the great work!



Marcos explained to us why he chose PLA/PHA: “I chose natural pla by colorFabb, because I had already used it in other projects and it’s a very silky touch filament, even with high layer heights, has a great finish, it’s quite easy to print, resistant, and, most of all because it doesn’t come from petroleum.”

PLA/PHA is our signature PLA filament which was the basis of colorFabb’s first product line. The added PHA makes our grade of PLA tougher and less brittle than generic PLA grades in the market. PHA (polyhydroxyalkanoate) is like PLA a bio-polyester, so our unique blend is still 100% biodegradeable. This material is available in multiple colors, but today we focus on the one without a color: PLA/PHA Natural.

We posted a dedicated blog back in 2017 to celebrate PLA/PHA Natural’s fourth anniversary. Read it here.

PLA/PHA Natural is available from stock and ships daily and worlwide for nearly 8 years already! Check the different spool sizes which are available in our webshop.


Fun fact: the brachiosaurus was the first digital dinosaur shown in the original Jurassic Park film.

Falcon 9

The sky is the place to be this summer… We’ve already shot some new drone footage and are heavily into RC planes (with some exciting news to come soon!). The sky, however, is a pretty big place and there is plenty to explore beyond the stratosphere. Enter SpaceX and its continuous news grabbing headlines with one succesfull launch after the next and, granted, some unsuccesfull ones. To honor them we decided to print the Falcon 9 rocket since our trusted Saturn V was feeling a bit lonely at the office.

Printed to scale

The Saturn V was printed by Korneel Bullens four years ago and it has survived multiple trade shows, one office relocation, a curious dog and the occassional cleaning accident. Now it’s time to extend the space port here at colorFabb with SpaceX’s famous Falcon 9.

Inspired by the latest Falcon 9 Crew Dragon launch we decided to print a model in the same scale as the Saturn 5 so we can get a great sense of scale between the two rockets.


The Falcon 9 is SpaceX’s highly succesfull two-stage rocket. Click here to have a good view on all sides of this rocket.

We combined files from two projects into one build:

  • The “Falcon 9 Model” by Anthony Williams (link here)
  • The “Dragon – M3” by An Duong (link here)

With some quick internet research we figured out the scale for the Falcon 9 and adjusted all the parts in the slicer software. Now, as printed, the Falcon 9 stands a proud 109cm but seems small compared with its 1960s classic brother the Saturn V which measures 180cm (rocket alone).

Unfortunately we had to scale down the Dragon M3 model too much for all the fine detail to be properly displayed. The model by An Duong is very detailed and would be best printed without scaling down. An Duong also offers an even more detailed version DRAGON – MS


For this model we used:

All three filaments are available now and ship daily from stock.

(The Saturn V was printed entirely with nGen – check out the original blog here).



More rockets and space ships will be added later…

Channel Wing

We have explored our LW-PLA filament being used for RC Planes before (here, here and here). Today we want to share Tom Stanton’s video where he continues researching the Channel Wing principle which was developed by Willard Ray Custer in the 1920s. The printed parts of the Channel Wing were made with LW-PLA. Now Tom will be building his own RC controlled channel wing aircraft and see how well it flies:


3D printing was used to create the curved airfoil shape of the channel wing. Using our LW-PLA the part is roughly 50% lighter then regular plastic as explained in Tom’s video.
The channel wing section it self was just shy of 28 grams.

The full scale Channel Wing concept

Granted, a lot was made using foam, but it’s cool to see LW-PLA being used this way in addition to the more traditional method.



At around 230C this material will start foaming, increasing its volume by nearly 3 times. Users can decrease material flow by 65% to achieve lightweight parts, or use the expanding properties to effectively reduce print time by using big layer heights or single extra thick perimeters.


For the filament to expand it is necessary to put a certain amount of energy into the filament. The amount of energy a filament can absorb during printing depends on the length of the hot-zone and the time it takes for the filament to pass through the hot-zone. The longer a filament will reside inside the hot-end, the more energy it can absorb which will increase the amount of expansion.


About Tom Stanton

Tom Stanton recently graduated with a degree in Aerospace engineering and has a huge interest in all aspects of engineering. But what he enjoys most is designing and building various projects that either he hasn’t seen done before, or at least hasn’t been carried out using a unique design/manufacture method.

His popular YouTube channel is being followed by over 400 thousand people and there is absolutely no reason you should not follow him as well. Check it out here.
