Captivated by the immense potential of LSPc, Reichental established Nexa3D in 2015 with a clear mission: to accelerate the adoption of industrial 3D printing through speed, automation, and material versatility. Just three years later, in 2018, the Californian manufacturer unveiled its first commercial 3D printer, marking its definitive entry into the competitive additive manufacturing market.

Initially, Nexa3D strategically positioned itself as an exclusive provider for the industrial 3D printer market, catering to demanding manufacturing environments requiring high throughput and precision. However, recognizing the burgeoning demand across various sectors, the company has since broadened its portfolio. This expansion includes specialized solutions for the dental sector, enabling the rapid production of models, guides, and prosthetics. More recently, Nexa3D made a significant stride into the broader professional market with the introduction of its first desktop machine, the XiP. Consequently, Nexa3D’s product lines now effectively serve multiple key segments: engineering (identified by an ‘E’ in machine nomenclature, such as the NXE200 series), dental (denoted by a ‘D’), and the increasingly accessible desktop market with the innovative XiP. Beyond its acclaimed resin-based systems, Nexa3D further solidifies its commitment to diverse manufacturing needs by offering a high-performance SLS printer, the QLS, demonstrating its comprehensive approach to additive manufacturing solutions.

The XiP, first publicly showcased at the most recent Formnext trade show in Frankfurt, represents a new frontier for Nexa3D, bringing industrial-grade performance to a compact desktop footprint. This robust ecosystem is not merely a 3D printer; it’s a complete additive manufacturing solution encompassing the XiP 3D printer itself, a dedicated post-processing machine for washing and curing, an essential air filtration system, and a range of proprietary resin cartridges. Designed to democratize high-speed resin printing, the XiP boasts a compact size and an attractive entry-level price of $6,295, making professional-grade additive manufacturing accessible to a much broader audience, from individual engineers and designers to small businesses and educational institutions.

After several months of eager anticipation from the market, the Nexa3D XiP was officially released last April, promising to redefine desktop resin 3D printing. At our 3Dnatives Lab, we were among the first to conduct an exhaustive test of the machine, putting it through its paces over several weeks. Join us as we delve into our detailed findings and share our comprehensive assessment of this exciting new offering from Nexa3D.

Unboxing the XiP 3D Printer: First Impressions and Build Quality

Despite its relatively compact desktop form factor, the Nexa3D XiP arrived at our lab securely packaged on a full pallet, underscoring its industrial-grade origins and the comprehensive nature of its ecosystem. The pallet contained not only the printer box but also the post-processing machine, a wide array of accessories, essential spare parts, and a selection of materials to get started. Unpacking the XiP itself proved remarkably straightforward. Once the four robust clips are released, the top section of the box effortlessly separates from the base, revealing the pre-assembled machine, ready to be placed on the workbench. Inside the main printer box, we also found the power supply unit and a stylish water bottle adorned with the Nexa3D branding, a thoughtful touch.

Delving into the other accompanying boxes, we discovered the post-processing machine, also arriving fully assembled, alongside a remarkably comprehensive accessory kit.

Furthermore, the package thoughtfully included two durable aluminum vats and a pack of three spare Everlast-2 membranes, ensuring longevity and uninterrupted operation.

While the provided accessory kit is undoubtedly extensive and well-curated for general use, our testing revealed that the addition of a pair of needle-nose pliers and fine-point tweezers would significantly enhance the user experience, particularly when tackling the delicate task of support removal. These tools are often indispensable for achieving pristine part finishes. Additionally, regular use of the XiP necessitates wearing gloves for safety and cleanliness. Although a single pair is provided, users will quickly need to purchase a supply of disposable gloves, as the initial pair is designed for single use.

It’s worth noting that our XiP unit was among the initial deliveries in Europe, and as such, the air filtration machine was not included in our specific package. However, Nexa3D has since standardized this offering, and the air filtration unit is now included as a standard component in all XiP packages. This crucial machine, designed to sit alongside the XiP on the workspace, actively draws in ambient air. It then employs a sophisticated combination of HEPA and activated carbon filters to effectively reduce Volatile Organic Compounds (VOCs) commonly associated with resin 3D printing, significantly improving the working environment. While the filtration machine greatly enhances safety, it is still recommended to wear a protective mask during operation, even though one is not provided by the manufacturer.

Visually, both the XiP 3D printer and its accompanying post-processing machine exude a premium aesthetic, characterized by a sleek combination of brushed aluminum and matte black plastic panels. This elegant design language extends to the resin cartridges, which are also crafted from aluminum. Nexa3D justifies its material choice not only for its superior aesthetics but primarily for its profound commitment to sustainability, recognizing aluminum as one of the most widely recycled raw materials globally. This ecological consciousness is integrated into the core design, with both the 3D printer and the post-processing unit featuring robust aluminum frames, mirroring the construction of the resin cartridges. Beyond its environmental merits, the aluminum construction imbues the entire Nexa3D ecosystem with a distinctive “premium,” minimalist, and thoroughly modern appeal, elevating it beyond typical desktop solutions.

Upon closer inspection of the printer’s interior, we were particularly impressed by the robust fixing system and the inherent parallelism of the build plate.

At the rear of the machine, users will find a comprehensive array of connectivity options for the XiP, including a USB B port for direct connections, an RJ 45 connector for stable network access, and the essential power socket.

Finally, while the XiP maintains a physical footprint (420x350x530mm or 77L) that is comparable to many other professional resin 3D printers on the market, it impressively distinguishes itself with a slightly larger printing volume (195x115x210mm or 4.8L) than many of its direct competitors. This optimized build volume, coupled with its compact exterior, allows users to print more parts or larger single components, enhancing productivity without demanding excessive workspace.

Installation of the Nexa3D XiP 3D Printer: A Seamless Setup

Once all the components are meticulously unpacked, the user’s initial task is to assemble the resin vat. This involves securely attaching an Everlast-2 membrane onto the aluminum vat frame using the four designated fixing clips. This ingeniously designed resin tray then slots effortlessly into the printer, held firmly in place by powerful electromagnets, ensuring perfect alignment and stability throughout the printing process.

Upon activating the machine for the very first time via the discreet power button located at the rear, users are greeted by a vibrant 5.5-inch color touch screen. This display is elegantly integrated into the front panel, appearing to vanish seamlessly when the machine is powered off, contributing to the XiP’s minimalist aesthetic. However, once illuminated, the screen springs to life with an intuitive interface designed for user-friendliness. The setup wizard promptly invites the user to scan a QR code, facilitating the association of the XiP with a personal user account – a crucial step for accessing online resources and managing print jobs. Next, the wizard guides the user to ensure the 3D printer is perfectly level; if not, the adjustable feet can be precisely manipulated to achieve optimal stability. The third step involves connecting the 3D printer to a local WiFi network, enabling wireless print job transfer and software updates.

To finalize the installation, a resin cartridge must be inserted into its designated slot. This cartridge, cleverly coupled with an ultrasonic sensor, enables the automatic and precise filling of the vat. A standout feature is that during printing, the resin tank is continuously monitored and maintained at an optimal level, thanks to a sophisticated flow system working in conjunction with the ultrasonic sensor, preventing print failures due to insufficient resin.

Overall, the installation of the XiP is an exceptionally quick and intuitive process. Nexa3D has gone to great lengths to simplify user onboarding, providing clear, step-by-step animations directly on the printer’s screen, further complemented by comprehensive video tutorials available on the manufacturer’s official website and YouTube channel. This dedication to user support ensures that even novices can get the XiP up and running with minimal effort.

Regarding the post-processing machine, its installation is equally straightforward. Users simply place it on their workbench and install a cleaning tray, filled with an appropriate post-processing solution such as Isopropyl alcohol or X-Wash, Nexa3D’s proprietary cleaning agent. For the subsequent post-polymerization (or curing) stage, prints are transferred from the cleaning tray to a transparent curing tray, which conveniently fits into the same slot as the cleaning tray. Once the reflective cover is securely installed, the post-processing cycle can commence. Adjusting the Wash & Cure parameters is intuitive: a button on the front panel toggles between cleaning and curing functions, while a rotary potentiometer, coupled with a clear 7-segment display, allows for precise setting of operating times.

Understanding LSPc Technology: Speed and Reliability Redefined

As previously mentioned, the XiP is a high-performance resin 3D printer that harnesses Nexa3D’s cutting-edge proprietary technology: Lubricant Sublayer Photo-curing (LSPc). At its core, LSPc builds upon the foundational principles of Masked Stereolithography Apparatus (MSLA) technology, utilizing a potent UV light source masked by a high-resolution monochromatic LCD screen to selectively cure layers of liquid resin. However, LSPc fundamentally differentiates itself from conventional MSLA processes through the innovative use of a continuously lubricated membrane. This critical distinction addresses one of the most significant drawbacks in “standard” resin printing: the peeling force required to detach each newly cured layer from the membrane.

In traditional MSLA, the printed layer must be forcibly torn off the FEP film at the bottom of the resin vat to allow for the subsequent layer to be exposed. This repetitive “peeling” action can lead to several problems. Fragile parts of a print are susceptible to damage or detachment during this stress, and in worst-case scenarios, the suction created can even cause the membrane to tear, leading to print failure and potential machine damage. Recognizing these limitations, various manufacturers have developed proprietary technologies aimed at “softening” or mitigating this peeling process.

LSPc technology tackles this challenge head-on. Nexa3D integrates a slightly elastic, lubricated membrane into its resin vats. This continuous lubrication creates a frictionless interface between the cured resin layer and the membrane. The primary, and indeed revolutionary, advantage of this technology over a conventional MSLA 3D printing process is the dramatic increase in printing speed. Because the layers can be detached with significantly less force and friction from the lubricated membrane, the typically time-consuming operation of peeling each layer is drastically reduced. This allows the printer to move much faster between layers, translating into print speeds up to 20x faster than comparable MSLA systems, making the XiP an exceptionally productive tool for rapid prototyping and batch production.

NexaX, Nexa3D’s Proprietary Slicer: Power and Potential

Once the Nexa3D XiP machine is unpacked and correctly installed, the next crucial step is to install the manufacturer’s proprietary slicing software, aptly named NexaX. This essential software, readily available for download from the Nexa3D website, serves as the command center for preparing print jobs. It encompasses all the fundamental file handling operations, allowing users to import, manipulate, and orient 3D models, along with a comprehensive suite of standard printing parameters necessary for configuring print quality, layer height, and exposure settings.

The NexaX software is notable for its tiered offering, distinguishing itself with a premium version available at a substantial annual subscription price of $1,199. This premium tier unlocks a range of more advanced printing parameters, providing expert users with granular control over every aspect of the printing process. Crucially, the premium version also grants users the flexibility to utilize resins from other third-party manufacturers, significantly expanding the material palette beyond Nexa3D’s proprietary offerings. This openness, albeit behind a paywall, is a welcome feature for users seeking greater material choice and potential cost savings.

At its core, NexaX is designed to be a highly intuitive slicer, offering all the most common and essential tools for successful resin printing. Users can easily move and rotate parts on the build plate, generate both manual and automatic supports with customizable parameters, and receive accurate estimations of print time and material quantity required for each job. Beyond these basics, NexaX integrates several particularly interesting and productivity-enhancing features, such as advanced duplication and stacking of parts (referred to as “array” functionality for batch production), as well as simplified STL repair and modification tools, which can save considerable time and effort in preparing models for print.

Despite its user-friendly interface and powerful features, our testing revealed some notable limitations within the NexaX slicer. Primarily, its compatibility is restricted to STL and OBJ file formats, with the more modern and efficient 3MF format regrettably overlooked. During extensive testing, particularly when generating supports, duplicating numerous parts, or saving large and complex files, we encountered noticeable slowdowns. These performance issues became particularly apparent when utilizing the “Array” functionality for the mass production of 170 units of a single model. This limitation could be significantly mitigated by incorporating support for the 3MF format, which is inherently lighter and more efficient to handle, thereby improving the fluidity of duplication and slicing for complex and high-volume print jobs.

Another compelling aspect of NexaX is its integrated wireless management interface for connected 3D printers. This feature proves exceptionally useful for users overseeing a fleet of machines, enabling efficient job management and monitoring from a centralized platform. However, it’s important to note that this functionality is currently limited to operation within a local network, which, while practical for most professional environments, may be a consideration for remote management scenarios.

In terms of material management, the design of the XiP prioritizes simplicity and efficiency. Installing and changing a resin cartridge is notably straightforward: it is simply inserted into its dedicated slot in the machine, where it automatically discharges the resin into the vat. A key feature of these cartridges is their integrated RFID chips, which enable seamless communication with both the 3D printer and the NexaX slicer, automatically adapting slicing parameters to the specific material loaded. However, during our evaluation, we noted that the full potential of these “smart” features appears somewhat under-utilized. For instance, the printer does not provide real-time information on the precise level of resin remaining in the cartridge, which could lead to unexpected print failures if not manually monitored. Moreover, while the cartridges are designed to be reusable, essential material information such as expiration dates or batch numbers cannot be updated, limiting comprehensive material traceability.

Although the XiP is positioned at the upper end of the desktop resin printer market in terms of its initial purchase price, this entry cost is notably offset by a comparatively low cost of consumables—specifically membranes and resins—when compared to other machines in its performance class. This long-term economic advantage makes the XiP a more sustainable investment over its lifespan. Furthermore, the XiP offers compatibility with third-party materials, provided users invest in the premium version of the proprietary slicing software.
