Dr. Fritsch is a leading developer of field-assisted sintering technology, offering FAST, SPS, and DCS systems engineered for precise, repeatable, and energy‑efficient densification. These sintering furnaces use controlled electrical energy, Joule heating, and applied mechanical pressure to achieve rapid consolidation of ceramic materials, metal powders, and hard‑to‑sinter composites. With carefully managed sintering parameters, including temperature control, pressing force, and pulsed current delivery, the systems support uniform heat distribution and efficient powder consolidation across a wide range of research and development scenarios.
The technology supports materials such as tungsten carbide, diamond particles, ceramic bonds, chromium powder, and metal‑bonded grinding tool matrices—applications where thermal conductivity, grain retention, and critical bond strength are essential. FAST/SPS sintering enables stable phase transformations and consistent microstructures, helping researchers optimize wear behavior, abrasive layer performance, and the overall structure of materials. Optional features such as pyrometer measurement, inert gas flow, graphite dies, and vacuum chamber configurations allow users to refine sintering cycles for improved part quality.
Engineered with German precision, Dr. Fritsch sintering systems emphasize reliability, temperature accuracy, and repeatable pressing motion supported by advanced sensor systems. These laboratory sintering presses and chamber furnaces provide stable operation for sintering ceramics, sintering metals, cold‑pressed green parts, and other high‑performance components.

Upstream Materials and Tooling Variables in Field-Assisted Sintering Outcomes
Field-assisted sintering technology consolidates what is placed inside the die, and the quality of the sintered part reflects decisions made well before the press cycle starts. Powder particle size distribution, green body compaction method, and die material all introduce variables that the sintering system cannot compensate for once the run begins. Specifying the surrounding process conditions alongside the sintering parameters is what gives FAST and SPS data its comparative value across experiments.
Powder Preparation and Green Body Compaction
Particle size distribution and morphology set the packing density of the green body, which determines what fraction of densification the thermal cycle must accomplish. A ball mill reduces agglomerates and narrows the size distribution of powders before compaction, and the reduction in particle size variance translates directly into more uniform current distribution during SPS. The pressing step that establishes the green body geometry before sintering depends on die precision; the view all options in the pellet pressing dies range covers cylindrical die sets in standard SPS tooling diameters that produce repeatable cross-sectional area and thickness across a run matrix.
Conventional Furnace Alternatives and Crucible Selection
FAST and SPS consolidation occurs under uniaxial pressure inside a die, a geometry suited to disc and pellet forms. Sintering steps that require atmospheric conditions, free-standing geometries, or longer soak times at intermediate temperatures use conventional equipment from the view all options in the laboratory furnaces collection, which covers tube, box, and chamber configurations for pre-calcination, post-sinter annealing, and thermal treatment of irregular part geometries. For samples requiring containment in a non-conductive vessel during downstream processing, an alumina crucible for research labs provides chemical inertness and dimensional stability to temperatures that exceed typical SPS operating ranges.
Rapid Solidification as a Complementary Consolidation Route
Where SPS densifies powder under pressure through solid-state diffusion, an arc melting furnace achieves full fusion of the same precursor materials and rapid quenching to preserve high-temperature phases. The two routes produce fundamentally different microstructures from the same elemental composition: SPS retains powder-scale grain structure through diffusion bonding, while arc melting imposes a cast microstructure through complete melt. Comparing properties from both routes on the same composition is a standard approach in high-entropy alloy and refractory intermetallic research.
Field-assisted sintering results are determined by the powder preparation, tooling geometry, and thermal processing conditions that surround the SPS cycle as much as by the cycle parameters themselves.

What to know before you buy
This collection brings together Dr. Fritsch field-assisted sintering presses and the powder preparation machines that feed them. The presses are the LSP 100 laboratory sintering press, the MSP-5 and the DSP-507, DSP-520/535 and DSP-615. Each is listed for FAST, SPS and DCS processes, which heat the die and powder with electric current while the press applies load.
To narrow the choice, start from the part you need to make. Compare pressing force, die size and temperature range on each product page with your target sample size and material. A lab making small research samples has different needs from a group producing prototype parts in batches, and the LSP 100 is the model built as a laboratory press.
Powder preparation before the press also shapes the result. The Dr. Fritsch 3D Powder Shaker Mixer blends powders, the GA 300 and GGM 130 machines granulate them, the DWA11 meters doses, and the KPV 300 volumetric cold pressing machine forms compacts before sintering.

Frequently Asked Questions
What is the difference between FAST, SPS and DCS?
They name closely related processes. Field-assisted sintering technology, spark plasma sintering and direct current sintering all pass electric current through the die and powder while applying uniaxial pressure. The names come from different research communities and current types. Every press in this collection, such as the DSP-507, is listed for all three.
Which press should a research lab start with?
The LSP 100 is the model listed as a laboratory sintering press, so it is the usual starting point for materials research. For larger parts or prototype runs, compare the MSP-5, DSP-507, DSP-520 / DSP-535 and DSP-615. Match pressing force, die size and temperature range to your parts.
What do the mixing, granulating, dosing and cold pressing machines add?
They prepare powder so each die gets a consistent fill. The 3D Powder Shaker Mixer blends powders, the GA 300 and GGM 130 granulating machines improve flow, the DWA11 meters doses, and the KPV 300 volumetric cold pressing machine forms compacts. Labs that make many parts from one powder often add these steps.
Can I get a quote for a specific material and part size?
Yes. Send the material, part diameter and thickness, and the number of parts you expect per run through the quote request form. Those details determine which press and setup fit, so the quote can match your application.
How do I order several machines for a full powder to part line?
Use the bulk order request form and list each model with quantities, for example a 3D powder shaker mixer, a GGM 130 granulator, a KPV 300 cold press and a DSP-507 sintering press. Putting the whole line in one request keeps the quote in one place.
