3D打印行业评论Nexa3d XIP 3D雷竞技在线登录打印机。
总部位于加利福尼亚Nexa3D将其树脂系统推销为“从“拨号互联网”到“宽带”的时代，以“采用当前的增材制造速度”。雷电竞充值将此和其他主张付诸实践，我们的工程团队已经审查了Nexa3D XiP, the firm’s latest ultrafast desktop 3D printer.
With the XiP, Nexa3D has made its first foray into the desktop market, having previously launched the larger NXE 400Pro and QLS 820 systems. However, with the XiP, the firm hasn’t skimped on quality, and users can expect to benefit from its usual technical prowess, albeit at a more affordable price.
XIP的核心是Nexa3d的润滑剂sublricant photo-Curing（LSPC）工艺。LSPC本质上是一种增强的蒙版立体光刻（MSLA）技术，在XIP的情况下，它允许以每小时18厘米的速度3D打印大型型号。

它比其他树脂系统便宜，它还可以处理4K质量的印刷品，其细节为50µm。为了额外的好处，Nexa3D将XIP设计为开放材料。因此，采用者可以配置第三方树脂，以与他们的机器一起使用。
In our review, we’ve taken a deep dive into the proposed benefits of these features, through our usual set of resin tests and benchmarks. This, in turn, allowed us to accurately gauge the quality of the parts the XiP’s able to produce. Read on for our full impressions and verdict on the machine’s capabilities.

XIP的标题速度和准确性好处在很大程度上取决于其构建的LSPC技术。使用机器，Nexa3D有效地从其工业树脂打印机中采取了这项技术，并将其缩小到台式机尺寸。该过程本身涉及使用LCD光掩模来阻断LED阵列，以便它只能通过材料固化所需的光。
这与传统的SLA系统形成鲜明对比，后者倾向于使用激光来绘制印刷品区域，从而固化树脂。
On the software front, the XiP relies on ‘NexaX,’ a perfect example of a slicer that’s designed to serve a particular system. The system’s interface was clean while providing access to all the options and settings resin printer users have come to expect.
这种可及性重点也反映在机器的其他区域。可以通过Wi-Fi或USB发送印刷品，并且在印刷品之间几乎不需要校准。如果打印是成功的，则用户只需要删除零件并清洁构建板即可。更重要的是，当该交换树脂时，用户可以将其从固定到位的电磁体中脱离增值税，并用新鲜的增值税替换或清洁当前的增值税，该功能可以最大程度地减少人体错误。
在实践中，可以通过墨盒垂直坐在机器后部并与床上的托盘对准树脂。这使得充满了无缝且干净的体验，并确实显示了Nexa3D如何优先考虑效率。

XIP是为谁设计的？
While marketed towards professional users with engineering, manufacturing, and digital dentistry application needs, the XiP is also more than capable of creating figurines and prototypes. As our tests below reveal, the machine delivers a particularly high level of finish. At face value, this supports Nexa 3D’s assertion that the XiP can be used for product development or the 3D printing of end-parts.

Unboxing and setting up the XiP
The XiP itself came well-protected. As the machine is constructed from heavy billet aluminum, it is important to keep it isolated, as any large hit would put it at risk of damage, but the Z-axis was well-secured using aXiPtie.

Inside the box, we received everything needed for printing and maintenance, including a resin, Wash+Cure, post-processing liquid, tools, and a USB stick. Those seeking to go the extra mile can also order a Team/Prototyping package with resins and membranes, but we didn’t miss them.
With the exception of the resin vat and build plate, the XiP came fully assembled, in a way that would likely make things easier for newbies. Initial impressions of the machine’s black & silver exterior were also positive, and its robust construction was later found to be less vulnerable to vibrations.

Reviewing the NexaX slicer
Free to download from the Nexa3D website, the NexaX slicer was designed in-house, and the companies expertise really shines. From our experience, this was one of the easiest resin-slicing jobs we’ve ever done, and the print preparation screen was clear and concise, offering up preloaded print profiles.

During usage, the slicer was much the same as others, and comes with the tools needed to 3D model with precision. These options let users organize multiple parts, add supports, and reorient for best results.
That said, the support option only auto-generated supports, and there was no manual option. The slicer also seems to use a lot of computing power and take longer than expected to load when other programs are open, something users may need to keep an eye on.

Benchmarking the XiP 3D printer
As always, we started benchmarking with the classic Benchy, a popular test that allows for the assessment of overhangs, bridges, and precision. Generally, if this print fails then either tuning is needed or there is a more serious problem, but the XiP produced one of the finest ‘benchies’ we’ve seen.
然后，我们继续进行重复性测试。为此，在将它们与计算机模型进行比较之前，我们生产了具有相同维度的多个部分以识别偏差。在此测试中，XIP得分良好，平均偏差为0.0565mm，而我们的预期却超过了。但是，Z轴的性能稍差，标准偏差为0.125mm，使XIP的总分下降。

Bottom Z-layers are supported though, and will therefore naturally be less accurate. If the first layer does not stick perfectly, this will also remove 0.10mm from the Z height. As such, the result can be seen as consistent, and not necessarily due to inaccuracy.

总体而言，就质量而言，印刷品非常完美。表面光滑，没有层分层。清洁后，零件就会亮起，尽管支撑件确实留下了一些标记。

接下来，我们进行了一项高度测试，以衡量是否可以达到列出的195mm x 115mm x 210毫米构建体积。我们通过3D打印20mm x 20mm x 210mm的塔，带有一个小的表面积，这样我们也可以测试床的粘附质量。
This print proved a success, as there was less than a 0.05mm deviation from the reference size. Later, in another test, we printed a piece that covered the full build area with similarly impressive results.
Going on to assess the XiP’s overhang capabilities, we then created a six-wall print with different overhang angles, ranging from 40° to 60°. These printed perfectly until 65° where there was slight curvature in the overhang wall, though this is the generally accepted limit for resin 3D printers.

As usual, we also tested for ‘capability.’ Stemming from the 1970s US auto industry, the concept sees statistical process control used to weigh up the suitability of a machine or process to achieve a required manufacturing output. To test this, we 3D printed 150 parts from xABS3843 and chose to measure the deviations in 16 of these.

In our tests, the XiP demonstrated a process capability (cp) of 1.89, a measurement that indicates the printer operates with precision. This, however, does not take into account the accuracy of the machine. For this, we obtained a coefficient of 0.79, showing that the machine slightly lacked in accuracy, as it decentred downwards.
If we wanted to use the machine to manufacture a part requiring a high degree of precision, we would therefore have to apply a correction coefficient to adjust for machine error. In such cases, builds would tend to be smaller instead of larger than desired, but it is possible to tweak CAD models to reflect desired tolerances.
Testing potential XiP applications
During testing, we produced various prototypes, one of our favourites being an injection mold for a 3.5mm headphone jack.
To create this, we used Nexa3D’s xPEEK due to its high-heat resistance, a trait the part would need if it were to find end-usage. In particular, we found xPEEK useful in the reinforcement of areas subject to the greatest change in temperature.

We also 3D printed a motorbike tail light from xPP405, a semi-rigid, tough resin with a high environmental resistance. As opposed to materials like ABS, which crack under pressure, Nexa3D’s polypropylene can also survive small impacts without capitulating.
One of the more decorative items we produced, was a wine bottle holder. This showcased the XiP’s large build volume. The part was made from Nexa3D’s xABS resin, and printed perfectly, with little to no supports or artifacts left behind.

There were no real negatives to the XiP. We had slicer display issues, but this will likely be patched. The other problem was the post-processing vat’s magnetic stirring mechanism, which lost magnetism as the motor got up to speed. This caused the system’s propeller to vibrate, rendering the wash+cure system unusable, but there were no faults with the printer itself, just its peripherals.
总体而言，NEXA3D的XIP提供了广泛的材料兼容性和应用，使其成为专业人士的绝佳打印机。对于那些需要精确，可靠的3D打印机的人来说，我们认为这是完美的选择。
NexaX is extremely easy to use and provides a great user experience. We really liked the stacking mode which allows for part mass production via stacking and support management. It is also possible to create material profiles. The only issue we had was an occasional display glitch, but this didn’t take away from the overall experience.
Better than average in terms of accuracy, and supported by an extensive product ecosystem, we reckon that with a few tweaks, it could be one of the best professional all-in-one printers on the market.
