Additive Screen Printing: Scalable Production Meets Micro Precision

Why It Matters

ASP offers manufacturers a cost‑effective alternative to molds and powder‑bed AM for high‑volume, fine‑detail parts, opening new opportunities in heat exchangers, medical devices, and electronics.

Key Takeaways

• Screen‑based additive printing creates thousands of parts per pass
• Wall thicknesses reach 75 microns; internal channels 125 microns
• Tooling cost far lower than injection‑mold tooling
• Build rates up to 10,000 cm³ per hour
• Compatible with metals, ceramics, polymers, and biomaterials

Pulse Analysis

Additive Screen Printing bridges the gap between traditional screen printing and modern additive manufacturing, delivering a surface‑based approach that sidesteps many of the handling challenges of powder‑bed processes. By pushing a material paste through a finely patterned screen, ASP can define geometry in the X‑Y plane while layer thickness is controlled vertically, allowing engineers to build complex, high‑resolution parts without the need for expensive powder handling or post‑processing steps.

The material palette of ASP is unusually broad, encompassing stainless steel, copper, aluminum oxide, zirconia, aluminum nitride, and a range of polymers and biomaterials. After each thin layer is cured with infrared or UV energy, the part is sintered, achieving over 96 % density and wall thicknesses as thin as 75 µm. These specifications make ASP ideal for heat‑exchange components, micro‑fluidic channels, and lightweight structural parts where thermal conductivity and mechanical strength are critical. The ability to embed closed internal channels directly during printing eliminates assembly, reducing part count and improving reliability.

From a production standpoint, ASP’s scalability stems from its reliance on screen tooling rather than custom molds. Screens can be fabricated in days and swapped quickly, keeping tooling costs low. Throughput is dictated by screen area, not part complexity, with systems capable of processing up to 40 carriers simultaneously and delivering 10,000 cm³ per hour. This translates to tens of thousands of micro‑precision components per shift, positioning ASP as a compelling solution for industries seeking high‑volume, high‑detail manufacturing without the capital intensity of traditional molding or the slower build rates of conventional 3D printing.
