by Editorial Staff: We are a team of 3D Printing Enthusiasts who have build a lot of knowledge about 3D Printing the last 8 years. Our aim is to create the knowledge hub for 3D Printing covering all minor and major topics. Providing one source of reliable Information for everybody regardless of Beginner or Expert.


In the dynamic world of 3D printing and additive manufacturing, innovative technologies constantly reshape the landscape. One such breakthrough is Hybrid PhotoSynthesis (HPS), a technology that promises to revolutionize how we approach 3D printing. This article delves into the details of HPS, comparing it with other prominent 3D printing technologies to provide a comprehensive understanding of its capabilities and advantages.

Understanding Hybrid PhotoSynthesis (HPS)

What is HPS?

Hybrid PhotoSynthesis (HPS) brilliantly coalesces the energy from two light sources, DLP & SLA Laser, creating a harmonized light engine that effectively combines the advantages of the two light sources.

Eliminating the need for post-print refinishing by ensuring a superior surface without any aliasing or stair-stepping.

HPS vs. Other 3D Printing Technologies

HPS vs. Vat Photopolymerization (VPP)

Vat Photopolymerization, an umbrella term for technologies like SLA and DLP, relies on curing liquid resin in a vat. HPS, in contrast, combines resin curing with a powder bed, offering greater support and stability for complex designs.

HPS and Masked Stereolithography (MSLA)

While MSLA uses an LCD screen to shape each layer, HPS enhances this process with its hybrid approach, allowing for faster production and more intricate designs.

Comparing HPS with Digital Light Synthesis (DLS)

DLS is known for its speed and continuous printing capabilities. HPS, with its hybrid technique, offers a higher resolution and smoother surface through the laser.

HPS vs. Direct Light Projection (DLP)

DLP uses digital micromirrors to shape each layer. HPS, however, integrates this technology and increases its precision with the support of an SLA unit.

Stereolithography (SLA) and HPS

SLA, a pioneer in 3D printing, offers high precision with resin. HPS takes this further by adding a DLP unit, which increases the speed that SLA alone might struggle with.

Lubricant Sublayer Photo-curing (LSPc) vs. HPS

LSPc focuses on reducing peel forces during printing. HPS addresses this issue inherently with its hybrid method, enhancing print quality.

HPS and Lithography-based Ceramic Manufacturing (LCM)

LCM specializes in ceramic materials. HPS extends this specialization to a broader range of materials, including ceramics, with its versatile printing method.

Continuous Digital Light Manufacturing (cDLM) Compared to HPS

cDLM stands out for its continuous printing capability. HPS matches this speed while offering the added benefit of printing more complex and delicate structures.

Lithography-based Metal Manufacturing (LMM)

LMM is tailored for metal printing. HPS extends this specialization to a broader range of materials, including ceramics, with its versatile printing method.

HPS vs. Two Photon Polymerization (2PP)

2PP excels in micro-scale precision. HPS, though not as focused on the micro-scale, offers a broader range of applications with its hybrid approach.

Advantages of HPS Technology

Speed and Efficiency

HPS is significantly faster than traditional 3D printing technologies, making it ideal for large-scale production.

Precision and Complexity

The hybrid nature of HPS allows for the creation of extremely complex structures with a high degree of precision.

Material Versatility

HPS can work with a wide range of materials, including resins, ceramics, and potentially metals, offering greater flexibility in applications.

Reduced Waste and Cost-Effectiveness

The powder bed in HPS reduces material waste, making it a more cost-effective and environmentally friendly option.

Applications of HPS

HPS finds applications in various fields like aerospace, automotive, medical, and consumer goods, where precision, speed, and material diversity are crucial.


Hybrid PhotoSynthesis stands as a remarkable innovation in 3D printing technology. Its ability to blend speed, precision, and material versatility sets it apart from other methods, marking it as a technology with the potential to redefine additive manufacturing.
