LEHVOSS Group to exhibit high-performance, sustainable 3D printing materials at Formnext

At Formnext, the LEHVOSS Group will showcase innovative, polymer-based precision 3D printing materials and their applications
.
Shows how to take into account the high demands of end customers on product quality, repeatability and processability
.
The topic of sustainability and profitability is also a focus
.
In the field of 3D printing, the demand for sustainable materials is also growing
.
LEHVOSS Group has launched its LUVOCOM 3F eco PET
.
The material is 90% based on recycled PET and is currently the most recycled PET 3D printing material on the market
.
LUVOCOM 3F eco PET is designed for the FFF (Fused Filament Manufacturing) and FGF (Fused Pellet Manufacturing) processes
.
Like all products of the LUVOCOM 3F product range, this material also impresses with its very good machinability and excellent product properties
.
Applications include functional prototypes and series parts in a wide range of industries including machinery, automotive and medical
.

The first product available is LUVOCOM 3F eco PET 50291 BK, a non-reinforced black type with an excellent surface finish
.
Its temperature resistance is as high as 125 ℃, and the water absorption rate is low
.
With the aforementioned properties, it has clear advantages over PETG, another variant on the market for 3D printing
.
In addition to the development of materials, it is also important to reduce the CO2 footprint in general
.
Today, the cost-optimized and operation-optimized lamination standards (lamination molds or lamination tools) created for the production of highly developed orthoses from CFRP laminates are still done using thermoset PU molded foam
.
These materials are all milled, as well as post-mold processing, which creates waste
.
In a case study, we worked with adViva to investigate the mold making process using 3D printing
.
LUVOCOM 3F PET CF 9780 BK was selected as the research material
.
It is characterized by high strength and high temperature resistance
.
Also, it has good chemical resistance and is easy to print
.
Process-related requirements, such as the required heat resistance and protection from moisture during curing in an oven vacuum process, are fully met by the printed laminate form
.

Thanks to the minimal amount of material used when building the model - with the high strength support of the chosen 3D printing material - it is possible to work with very little infill (support structure in the part)
.
This results in a smaller volume of material as residual material
.
LUVOCOM 3F PET CF 9780 BK can be collected individually and sent for technical plastic recycling
.
After the parts are ground, new technical parts can be manufactured using methods such as injection molding
.
Once the process is established in this application, the sorted return of the material can be organized, and nothing will hinder the recycling
.

Automotive SLS Material Portfolio

The LEHVOSS Group presents a complete range of LUVOSINT materials, perfectly designed for use in automobiles, based on PP, PA12 and PA6
.
All materials are highly cost-effective
.
Unlike existing materials, LUVOSINT materials are fully reusable and do not require disposal of used powder
.
"In the context of the current discussions on microplastics and sustainability, non-reusable SLS powders are not feasible for industrial use," says Marcus Rechberger, LUVOSINT Product Manager
.
The material in the automotive portfolio has been dyed into real black, so no additional dyeing process is required
.
All materials have high stability, for example LUVOSINT PA6 8834 BK can be run with higher oxygen content in SLS machines, which can save a lot of nitrogen
.
For the LUVOSINT PA12 9270 BK, LEHVOSS is working with Cirp GmbH, an SLS service provider located in the heart of the German automotive industry
.
Cirp specializes in high-quality automotive 3D printed products
.

The Perfect Product Using Hybrid Technology: Blobber Bike Saddle

LEHVOSS will demonstrate a perfect example of hybrid technology, an effective combination of SLS powder printing and traditional casting
.
Blobber is the product name for a new bicycle saddle, invented in Austria and designed by Austrian engineering and 3D printing company NEMETON
.
NEMETON is an expert in polyurethane processing and a loyal user of LUVOSINT TPU X92A
.
Blobber offers a new concept of customizing a bicycle saddle for each rider
.
The heart of the invention is an inflatable and removable upper saddle
.
The seat pad consists of a shell, cast from PU, but this shell is surrounded by an internal SLS-printed lattice structure
.
Harald Stepanovsky said: "We used the LUVOSINT TPU X92A
.
This hybrid concept guarantees performance, comfort and cost-effectiveness
.
We did pass a very strict TÜV testing procedure, so we rely on the LUVOSINT TPU X92A, which offers the most robustness on the market Printed material
.
” Blobber saddles will soon be available on public rental bikes in Austria, with more countries likely to follow
.
