Everything about 3D printing and 3D design

Here you will find all information about FDM 3D printing, our range of materials, qualities and how best to get your 3D design.

The FDM printing process

This printing process is based on the layering of plastic that is melted. This works similar to a hot glue gun that is moved by a computer-controlled machine.

The printing material is called filament and is wound up as thread on a spool.

surfaces

Because of the layering process, there is always a bottom of the model that is in direct contact with the print bed, as well as a top and the remaining sides. As a result, not every page looks the same in structure and appearance, depending on how the model was oriented during printing.

However, we always try to find the optimal print orientation for you for the best effect!

support structures

Complex models with large overhanging elements that need to be supported by support structures can also have somewhat unattractive surfaces at the points of contact with the supports. (Depending on the nature of the contact point)

Again, we try to avoid supports as much as possible to achieve the best result.

tolerances

In FDM printing we calculate with average tolerances of +/- 0.5% with a lower limit of +/- 0.3mm.

Most of the time we can do it more precisely, but in general you have to plan for tolerances in the 3D design for 3D printing.

  • prototype quality

    With a layer height of 0.3mm, it is very well suited for quick tests.

  • standard quality

    With a 0.2mm layer height, the best ratio of printing effort and quality.

  • Fine quality

    With a layer height of 0.15mm you can achieve even more beautiful surfaces.

  • Extra fine quality

    With a layer height of 0.1mm, even the smallest details can be reproduced

  • Standard material: PLA

    The typical 3D printing material for everything that needs to look good. It is rigid, stable and can be easily reworked.

    It is the best printable material on the market with the widest range of colors and effects.

    The only disadvantage is that it doesn't tolerate UV light very well in the long run and starts to soften at 50°C.

  • Standard material: PETG

    The standard material when it needs to be a little more impact-resistant. It has a slight flexibility, which makes it a bit more resilient.

    In addition, it is UV-resistant and can withstand temperatures of up to 70°C before it begins to soften.

    On the other hand, it cannot be reworked so easily and can only be firmly glued with a few adhesives.

  • Standard material: ASA

    From the properties, this material combines the properties of PLA and PETG. It is rigid yet slightly flexible.

    It is UV-resistant, only softens at 95°C, can be reworked and glued very well.

    It is more complex to print and is slightly worse than the specific material in every property.

    Simply an all-rounder.

  • Special material: TPU

    When it needs to be flexible, this rubber-like material is used.

    We have the material in different hardnesses.

    (Shore A85-D58)

    It can be challenging to print, but due to its extreme flexibility, UV resistance and temperature resistance of up to 110°C, it provides good prerequisites for special requirements.

  • Special Material: Nylon CF

    The premier class in FDM 3D printing. This material is extremely difficult to print but offers unique properties.

    We use material that incorporates small carbon fibers for a little more rigidity.

    It is extremely tough, slightly flexible, abrasion resistant and stable up to 150°C.

    Perfect for small heavy duty parts.

  • Special material: PC

    If it has to be rigid and stable, we use polycarbonate.

    It is demanding to print but offers a very good overall package.

    It is always used when you need rigid, resilient connections.

    In addition, it is extremely UV-resistant and dimensionally stable up to 110°C.

    An extreme all-rounder.

Post-processing of 3D prints

Many prints that we make are intended for use in costumes. For the best print quality (to minimize post-processing) and easy post-processing, we use PLA as a base material unless otherwise requested.

Here you will find a summary of what you have to consider.

  • Deform

    Since most parts are not 100% plastic, care must be taken, but generally parts can be deformed when exposed to heat. PLA from approx. 55°C, PETG from approx. 75°C, ASA from approx. 100°C

  • Ribbons

    Since it is still plastic, care must be taken when grinding that not too much friction heat is generated. It's better to be slow and steady than too fast. PLA and ASA are the best to grind, although you should always wear respiratory protection!

  • gluing

    As a rule, you can try any glue that glues plastics, but we have had the best experience with the following: UHU Allplast for household plastics, plastic on plastic), superglue (all-rounder), UHU Plus Endfest (plastic+other materials)

  • putty

    Even if we work very precisely, slight edges can occur when gluing or if you want to rework something yourself. Our models can be reworked with simple fine filler or similar without any problems.

  • prime

    In order to get rid of the last lines, our components can be primed without any problems. We recommend a slightly thicker primer, such as spray rubber or similar, to obtain a homogeneous surface as it can fill the fine grooves.

  • Paint

    Our models can also be painted directly without priming. Acrylic paints have proven to be very reliable. After a primer, you have to see which colors are compatible.

    Warning: PETG is difficult to paint!

3D designs

The basis of every 3D print is a 3D design. When it comes to technical CAD designs, we can help you with the creation!

For homogeneous, artistic designs, we may be able to put you in touch or give you tips on how we can achieve the desired result together.

You can often find ready-made models in one of the many databases. Many designs can be used free of charge for personal use, where we are happy to act as a service provider for you to print the desired design!
