What is additive manufacturing?

The manufacturing process of joining materials together to create three-dimensional objects layer by layer from digital 3D data.

Additive manufacturing has the potential to transform the manufacturing industry along supply chains, digital warehouses and enables rapid adaptation to solve current problems. It is always about choosing the appropriate application, technology and design approach.


How is additive manufacturing different from conventional manufacturing?

In additive manufacturing, the material is added layer by layer; in conventional manufacturing, the material is either removed, shaped or added throughout the volume.


What are the main advantages of additive manufacturing?

Design freedom, speed of delivery, cost reduction, part personalization, one-piece part assembly joining and technology sustainability.

These are the top 6 advantages of additive manufacturing. You can read more about each on the Additive Manufacturing page.

and their properties


What is the temperature resistance of PA2200, PA3200GF and MJF PA12 materials?

Operating temperature should be understood as another of many factors influencing the properties of a given material. For this reason, temperature resistance cannot be determined as one specific value for one specific material. In order to accurately determine it, it is necessary to know the application, the method and degree of loading and other environmental influences.


How do the mechanical properties of PA2200 and PA3200GF differ?

PA2200 represents the trade name of EOS GmbH for polyamide 12 white. PA3200GF represents white polyamide 12 with the addition of glass beads.

Mechanical properties vary quite considerably despite the same base material. The greatest difference can be observed in the stiffness of individual materials. Young’s modulus of elasticity in tensile PA3200GF is 52–⁠94% higher than that of PA2200. This characteristic describes the degree of elastic deformation under static tensile load.

In other words, under the same tensile load, PA2200 reacts with elastic deformation that is approximately 1.5 to 2 times higher than that of PA3200GF.


Do PA2200 and PA12 parts float on water?

The density of EOS PA2200 (~930 kg/m3) is lower and the density of HP PA12 (~1010 kg/m3) slightly higher than that of distilled water at room temperature (~998 kg/m3). The highest density is at 3.98 °C (~1000 kg/m3) and the lowest is at boiling point (~958 kg/m3). However, over the entire range of liquid water, PA2200 should float on the surface and PA12 will not float.

This may be affected by differences in the content of other substances in the water, trapping air on the surface or in pockets of a given part geometry, or nucleation of gases contained in the water on the surface of the parts.


Is the Alumide product conductive?

Despite the content of aluminum particles, Alumide can be described as an electrical insulator, as its surface resistivity is on the order of 1014 Ω. However, it is characterized by a relatively low electrical (impact) strength (0.1 kV/mm) at AC voltage.


Do any of materials meet ESD requirements?

The range of materials from EOS GmbH includes HP 11-30, which is characterized by electrostatically dissipative behavior. We do not normally produce this material, however, our production facilities have the capability to do so.

It is polyamide 11 with the addition of carbon fiber. Despite its carbon fiber content, the material exhibits a low level of anisotropy, or different properties in different directions. This material is characterized by very high rigidity. The mechanical properties greatly resemble PA3200GF, which we commonly produce.


Can you process multiple materials in one production cycle?

In the case of all our production machines, it is possible to use only one material in a single construction. However, it is possible to join two parts made of different materials after the production itself. The geometry of the individual components can be adapted to this connection, creating a joint that combines the advantages of an interlocking and a bonded joint.

Of course, it is also possible to use demountable joints for joining the parts, where it is also possible to take advantage of additive technologies to create complexly shaped joints.

and post-processing


What is the difference between SLS and MJF technologies?

In the case of SLS technology, the powder material is locally heated by laser and thus the powder is gradually sintered in the given layer, followed by the application of another layer of powder and its preheating. This process is repeated until the object is created according to the digital master.

In the case of MJF, two liquids are dripped into the powder layer of the material. One of them (the fusing agent) improves heat absorption through the material and the other (the detailing agent) improves the thermal conductivity of the powder. The fusing agent is transported in the form of drops to the places where the sintered part is to be created according to the digital master. The detailing agent follows the contour of the sintered part from the outside, ensuring that the treated powder has not been sintered.

Subsequently, the surface of the powder layer is gradually irradiated using a lamp and thus the sintering itself occurs. Another layer is applied and the process is repeated until the object is created according to the master.


Can you make a transparent part?

We can produce transparent parts! For this purpose, we use SOMOS WaterClear, which is designed for SLA technology.

This material is translucent immediately after production with a slight surface roughness, which we can reduce. Subsequent clear painting achieves excellent transparency of the part.


Can you "print" threads onto products?

Thread printing is of course possible and is a fairly common practice. However, it is necessary to mention that every combination of production technology and material has different technological possibilities. Very small threads may not be possible to produce.
It is always necessary to consult with us about the specific application.

There are many possibilities of solutions beyond printed threads. Thread inserts are commonly used, for example, or the thread can be cut into an already manufactured part.


What is the minimum manufacturing wall thickness?

Minimum wall thickness values are given for each material here and are valid for ideal situations.

Is it possible to plate manufactured parts?

Plating can be carried out on the basic untreated surface of plastic products, on a surface that has undergone chemical smoothing, but also on a ground and painted surface that guarantees a high gloss of the plated surfaces.The plated layer reaches a thickness of only a few microns, but exhibits very low electrical resistance.


What types of post-processing (surface treatment) do you offer?


Is it possible to bond parts and if so, how?

Part bonding is a common practice for us. We use it in cases when a part cannot be produced in one piece or for standard assembly bonding. Thanks to the additive manufacturing method, differently shaped interlocking joints can be prepared for bonding. The part is then divided according to the possibilities of the given production facility.

The input for the production of large parts is only the model with its final form. The part is then divided by our software. According to the described application, the material and technology are selected, and the part is then divided into smaller parts, depending on the possibilities of the selected technology. To better select the used joint and places for cutting, it is advisable to know as much detail as possible about the application. The cutting points are defined by our specialist using interconnected sections. The piece is then separated at this points and if necessary the selected interlocking joints are generated.

We use four basic types of joints. A wide range of adhesives are used for bonding, especially versatile cyanoacrylate adhesives or adhesives adapted to the needs of elastomers. We also use adhesives based on ethyl cyanoacrylate, which resist high temperatures. We use UV-curable adhesives for bonding components produced using SLA technology. The selected adhesive is always chosen on the basis of the specific application of the part.


What's the biggest part you can make?

The largest production chamber (800 x 800 x 600 mm) in our “fleet” is the RPS NEO800, which uses SLA technology. This value represents the current dimensional limit for the production of a single part in one piece. However, we also normally produce significantly larger parts that are digitally divided into multiple parts and that are connected, for example, by gluing after production. The joints are usually interlocking, which is made possible by the flexibility of additive technology.


How large is the building space of ONE3D’s production facilities?

Technology Equipment Production Area (W x D x H)
SLS EOS P396 325 x 325 x 588 mm
MJF HP MJF 5200 380 x 284 x 380 mm
SLA RPS NEO800 800 x 800 x 600 mm
DMLS EOS M400-4 400 x 400 x 400 mm

Is it possible to "reprint" something on a manufactured part?

It is possible to “reprint” parts in the case of SLM technology, where the part is milled to one level. The part is subsequently clamped into the chosen manufacturing device and becomes an imaginary production platform for the first layer.

In the case of polymers, the only option is to produce a “counterpart” which is then glued on.


What is the accuracy of manufactured parts – or a tolerance standard?

As part of our production, we guarantee the tolerance standard DIN ISO 2768-1, class C. If higher tolerance standards are required, an individual consultation regarding the specifications is necessary.
