1 Introduction

The worlds of **additive manufacturing** (3D printing) and **industrial printing** (UV flatbed) have long existed as parallel technologies, each with its own distinct strengths and limitations. 3D printing excels at creating complex, three-dimensional structures from the ground up, while UV flatbed printing is renowned for its ability to apply high-resolution, full-color graphics and textures onto flat and rigid surfaces. However, a significant technological convergence is now underway, blurring the lines between these two domains and unlocking a new frontier of possibilities. This fusion is creating a powerful hybrid manufacturing category that combines the **form-building capabilities** of 3D printing with the **surface-finishing prowess** of UV flatbed technology.

This merger is driven by the demand for highly customized, functional, and aesthetically sophisticated products across industries from aerospace to consumer goods. It represents more than just a sequential process; it is the integration of digital design and fabrication into a seamless, automated workflow. The result is the ability to produce objects that are not only structurally sound but also embedded with **high-fidelity graphics**, **textured surfaces**, and even **functional electronics** in a single manufacturing stream.

This article explores the technical advancements fueling this convergence, examines the groundbreaking applications it enables, and considers the future of this transformative synergy in modern manufacturing.

## 2 The Technological Convergence: A Hybrid Approach

The merger is not merely about using both technologies in tandem but about creating integrated systems and workflows where capabilities enhance each other. This convergence manifests in several key technological advancements:

### 2.1 3D Texture and Relief Printing

A primary breakthrough is the ability of advanced UV flatbed printers to deposit ink in layers thick enough to create tangible, **tactile textures** on a surface. This process, often called "2.5D" or **3D relief printing**, does not build a full three-dimensional object but rather adds a textured surface onto a pre-existing substrate. This is achieved through specialized inkjet printheads and UV-LED curing systems that can precisely jet and instantly cure inks in successive layers, building up height that can simulate textures like leather, wood grain, brush strokes, or even custom topographic patterns.

Innovations like **Z-axis height control systems** allow for precise control over this texture buildup. For instance, the eufyMake E1 supports a **5mm浮雕打印高度** (5mm浮雕打印高度), enabling it to create significant relief effects directly on a object's surface.

### 2.2 Integrated Printing and Curing Systems

Modern systems are being designed from the ground up to handle both additive construction and sophisticated surface decoration. This involves the integration of **UV-LED curing** technology, which is crucial for its instant curing capabilities, low heat output, and energy efficiency compared to traditional mercury-vapor lamps. This allows for the curing of inks on a variety of heat-sensitive materials and is a key enabler for the precision required in combined processes.

Some industrial systems are emerging that combine the strengths of both technologies. For example,珠海赛纳三维科技有限公司's SUV2512 3D UV平板打印机 boasts a high print resolution of 1200×1200 dpi and the ability to handle substrates up to 100mm thick, bridging the gap between traditional flatbed printing and the production of thicker, more object-like products.

### 2.3 Advanced Material Science

The fusion of these technologies is heavily reliant on advancements in material science. The development of specialized **UV-curable inks** and **resins** is critical. These materials must possess excellent adhesion properties to bond with various 3D-printed substrates (like plastics, resins, and metals), offer flexibility to prevent cracking, and provide durability against abrasion, chemicals, and UV light exposure.

Companies like井上新材料 are at the forefront, developing innovative UV resins with enhanced properties such as **high temperature resistance** for aerospace applications and **biocompatibility** for medical uses, thereby expanding the functional applications of merged 3D printing/UV printing outputs.
