can i spray coat a model to make it water tight ?

Can I make a PA 2200 (White strong material from Shapeways) model, water proof with some sort of spray coating ?

I know this is not directly ultimaker related but I know the People on this Forum are the smartest guys around for this type of question.

Why I ask is because I need to print out a rather large model 250 x 250 x 60 mm battery pack Shell casing that my Company is developing.

We are getting one printed from shapeways for around 260 euros.

But trying to find a Company that can print the same prototype model in a water tight material that we can also shock and Vibration test seems to be a Little tricky ?

Any ideas guys ?

Thanks guys.

Ian :)

Rapid Prototyping (RP), Additive Manufacturing (AM) or 3D print technology is

nothing but the layer by layer to build a product. For this, a print head is typically used, or by means of layers of powder a laser locally fused together. This method is the most complex designs possible that could never be achieved using conventional machining methods.


Although the technique is relatively new to all by now many kinds of materials, including metals, are processed so that the application and use has increased significantly. Some materials are porous after production and / or need extra protection against external influences. A liquid to be treated, to obtain gas-tight and protected product is the product DIAMANT DICHTOL.


One of the companies that has dedicated itself to this particular branch of production is the company 3dPrintcompany BV Hengelo. We asked Henny te Pas from this firm to his experiences:


Dichtol diamond in the 3D printing technology is mainly applied to plastic, as in our case based on PA12 nylon. Initially recommended by the manufacturer of the printing machines DIAMOND DICHTOL now widely accepted and appreciated by 3D printing companies.

The goal is on the one hand the impregnation of the plastic parts to achieve water and gas density and to improve the compressive strength, but also to seal the somewhat porous structure for pollution. This has proven expedient for objects that frequently go from hand to hand like show models and prototypes but also with utensils, additional protection simply necessary. Our standard used DIAMANT DICHTOL processing method of dipping is, unless the objects beyond a certain size, then pouring or spraying we impregnating the part with the Dichtol.

We are very happy with the end result. The DICHTOL gives our product a significant added value which the applicability and usability will be greatly increased.

You could go hardcore with a hydrophobic spray, but im not sure how long it would last for or even work, but i love that stuff.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
