MANUFACTURING OF FACE SHIELDS

We are currently manufacturing face shields. We developed the shield in collaboration with The Ajdovščina Civil Protection Unit and several of them are now in use at multiple dental clinics. Here are a few specifications:

  • ergonomic design
  • low profile (at the bottom part it doesn’t “stick” out and so it doesn’t obstruct the work)
  • it’s light
  • the transparent part is made of polished polycarbonate
  • can be used in combination with protective glasses
  • comfortable for long time wearing (fixed with two elastics -> doesn’t press on your head)
  • quality materials (PET-G and PC)
  • it protects from aerosols
  • easy to disinfect and clean  

Price of one unit is 10€ VAT included.

PRINTING OF FACE MASKS AND FACE SHIELDS

Thanks to 3D printing, we can manufacture a variety of different products, including toys,
souvenirs, spare parts, and even protective masks. This is our contribution towards fighting
the virus that has affected our lives in the last couple of weeks. The Ajdovščina Civil
Protection Unit invited us to collaborate in the project of printing reusable protection masks,
which are currently in prototype phase. We received a 3D file that needed a few corrections
and, pronto, the mask was ready for printing! Of course, the mask has to be complete with a
suitable filter to be safe for use. The printing of such masks requires extreme caution, since
such products have to be reliable and adequately tested; to this end, our mask will undergo
tests at a company in Ajdovščina, Slovenia.
It is important to note, however, that masks, produced with 3D printing are merely a
makeshift solution in case of mask shortage, which, we hope, will never take place.
In addition to masks, 3D printing allows us to produce protection face shields. We are
currently printing the first series of the model, developed by the Czech company Prusa,
which, if proved suitable, will be produced following the demand for the same.

NEW SOUVENIR

In December we started printing and selling a new souvenir of which we are very proud – a replica of the fairy tale train that drives tourists through Postojnska cave. The train is composed of many small details and colours, so the designing process was very challenging but the final product is therefore so much more rewarding. We are very excited to finally present you the train in 3D shape!

PRINTING SOUVENIRS – YOU CAN WRITE US FOR YOUR FREE SAMPLE!

Are you selling souvenirs? Would you like to offer a good quality, one of a kind souvenirs to your visitors? You can contact us, tell us your wishes and we will do our best and make something special just for you. 

We make souvenirs with 3d print technology so in that case we don’t have any big costs with manufacturing tools. 

Also – we use biodegradable plastics from european manufacturers with certificates. 

SLA 3D PRINT WITH ADVANCED MATERIALS

Prototypes are great for testing the ergonomics of the product. If we use the advanced materials and technologies for printing we can also test the mechanical characteristics of it.

We offer 3D print using a variety of advanced materials. One of them is a material that handles temperatures of +280°C heat and elevated pressures. In addition, we have flexible, rubber-like material and resins, which we print into material to look like polypropylene.

The pictures below show two products that have mechanical characteristics similar to ABS. We used the product in the first picture to make soft jaws for a CNC milling machine and the other two for testing the ergonomics and production strength of the parts in the electrical connection.

To achieve the exact characteristics of the above materials, we improve 3D printed products under 405nm UV light.

PRECISE SLA 3D PRINT OF SMALL ELEMENTS

Some of our prototypes are of smaller dimensions and have finer details printed on them. In this case, we use a SLA 3D printer. If necessary, we print the item in a 0,025mm resolution, which means that every vertical millimetre of 3D print is composed of 40 layers. At this resolution, the individual layers cannot be seen with bare eye.

An example of this kind of 3D print is this connector in the pictures below.

NEANDERTHAL FLUTE – THE OLDEST KNOWN MUSICAL INSTRUMENT EVER FOUND

3D print allows us to produce items with no extra costs or tools such as tools for injection of plastic. The operational principle of 3D print consists of adding material layer after layer and if we look closely at the printed object, we can see those layers with our bare eyes. In most cases these visible layers are not problematic, but sometimes costumers prefer prints that look as close as possible to the original. In that case, we need to extra process the prints with sanding, polishing and/or colouring. An example of this kind of product is this replica of Neanderthal flute. The Neanderthal flute is the oldest known musical instrument ever found in the world and it was made by aNeanderthal man who used a cave bear bone to make it. The flute was discovered in 1995 in Slovenia. We are proud to say that we print the flute replica sold as a souvenir at the National History Museum of Slovenia.

PROTECTIVE COVERS FOR LESS THAN €0.50/UNIT

A client wanted a protection cover for the front side of their product. We designed this plastic cover (80mmx65mmx23mm) which can be put in the box before sending/storing the product. In the pictures below, you can see six different covers, each in a different production phase. In this case, we talk about smaller production series (approx. 200-300 pieces/month). Such quantity can be printed in 24 hours and sold for less than €0.50/unit. This is a nice example of why 3D print can be used for the production of smaller series because there’s no need for manufacturing expensive tools for the injection of plastic. It is worth emphasizing that such prints are printed with rough print settings, because the covers are usually disposed after use and there is no need for finer details.

HOUSING UNIT FOR ELECTRONICS

Because of it price, the FFF 3D print technology is very accessible and convenient for manufacturing different kinds of housing for electronics. The advantage of printed housing for electronics is that we can completely adjust it to the components in the interior. Because of that, the electrician installing it will have a much easier task. In addition, the combination of different colours allows us to print different tags and inscriptions on the front side that will last forever (unlike stickers, for example). In case that the housing will be exposed to different environmental impacts, we can also add a 3D printed gasket, which we print in flexible material.

CONNECTION UNIT FOR ELECTRICAL WIRING

Our client wished to introduce improvements due to the complexity of the machine wiring and the consequential troubles they were facing during maintenance operations. They wished to develop a unit equipped with terminals or connectors which would include all bridges and electrical connections to plug in the cables.

To further facilitate the use of the unit, single wiring connections were arranged into groups. Based on the input from the client and the electrical wiring diagrams, we created a 3D model using a CAD tool which we then printed to obtain simplified versions of (non-working) prototypes. Some of these prototypes include connectors, while others incorporate terminals with screws. The client will test the single prototypes and choose one of them, according to which we will produce a working prototype equipped with all necessary electrical wiring.
