11.2023 Hard/Soft Combination, FDM Printing
Hard/soft combinations with co-recyclable products can now also be printed using the FDM/FFF or pellet printing process!
A very valuable feature, especially with filament printing, is that the spools do not have to be pre-dried.
These hard/soft combinations are also easy to produce in larger quantities using injection molding.

09.2023 Whether Flower Vase, Car Bumper or Technical Housing – Everything 3D Printed!
We like to use these vases to evaluate printability, layer adhesion and haptics. Shown here with a wall thickness of only 0.4 mm.
All polymers shown in these 3 vases look similar, but differ significantly from each other.
1) Vase large
– Product ID 1633, PX-DIPRO®blend H3.1H1Z64700F, or Product ID 1864, PX-DIPRO®blend H3H2Z14601EX –
Depending on the stiffness requirement, this demonstrator was made of DIPRO®blend H product ID 1633, PX-DIPRO®blend H3.1H1Z64*700F, or product ID 1864, PX-DIPROblend H3H2Z14*601EX. These two unreinforced and ultra-tough polymers have an Et Modulus of 856 MPa to 1,050 MPa and are virtually indestructible due to ultra-tough impact and notched impact properties.
2) Vase center
– Product ID 1832, PX-DIPRO®blend H3MT4H1Z24*800F –
In order to further increase the stiffness, 20 % mineral type “MT” was used for product ID 1832, PX-DIPRO®blend H3MT4H1Z24*800F. Now a housing material with Et Modulus of 1,520 MPa is available with high impact strength and still good notched impact strength. The surface finish is excellent.
3) Vase on the right
– Product ID 1831, PX-DIPRO®blend H3MTGF42H1Z24*800F –
For some housings, the above-mentioned stiffness is not yet sufficient, which is why Product ID 1831, PX-DIPRO®blend H3MTGF42H1Z24*800F, was developed as a housing grade with 20% mineral type “MT” and 10% special glass fiber for low-cost housing materials. The Et Modulus is now 3,030 MPa.
In addition to this group of polymers, 10 – 25% specialty glass fiber polymers are available up to 4,500 MPa tensile modulus.

Car storage tray for cell phone, cables and more
This material was chosen for automotive interior applications for the following reasons:
- medium stiffness
- extreme high notched impact strength
- heat deflection temperature HDT-B of 134 °C
- good heat aging behavior
- low material density of 1.01 g/cm³
- low part density due to INFILL of 0.75 g/cm³
- easy to print
- no pre-drying of the filament spool
- high absorption, no tendency to rattle
- matt black surface
07.2023 DIPRO®mid C Precision Polyamide with 15 % Carbon Fiber Establishes Itself
Minimal mold shrinkage (0.1%/0.1% – MD/PMD), high strength (153 /147 MPa – dry/conditioned), stiffness (11,100 / 9,700 MPa – dry/conditioned) and heat deflection temperature (HDT-B=200 °C) with simultaneous ESD (Electrostatic Discharge) properties enable forward-looking applications in FDM/FFF 3D printing.
01.2023 DIPRO®blend H and DIPRO®flex High-Performance Polyolefins with Minimal Mold Shrinkage for High Precision
Together with ROTFELD-Consulting, DIPRO®mat has been able to develop a range of unreinforced and special glass fiber-reinforced high-performance polyolefins (patent pending) that exhibit hardly any shrinkage, are incredibly tough and – unlike conventional impact-modified PPs – do not lose any heat distortion temperature, since a blend component provides a Tg (glass transition temperature) of 160°C.
This results in polyolefin compounds with high precision available for injection molding and 3D printing. An exciting fact is that the development started in additive manufacturing, where a large warpage is useless, and now returned to injection molding applications.
12.2022 First Processing with Adaptive IR Zone Heating System (FFF/FDM Printing)
The equally smooth surface coupled with high strength in the build-up direction was achieved with Apium’s patented IR zone heating system. In this process, only the uppermost layers are melted so that there is a high level of layer bonding. In the meantime, the lower layers can cool down without any further thermal influence on the surface quality.
