Phrozen's Sonic Mini and Mighty Series offer a low-cost entry into the world of resin 3D printing. They're ideal for hobbyists, students, and anyone getting started with resin 3D printing, but they do require a great deal of tinkering and time invested to achieve successful prints. Material selection is limited, which curbs the range of potential applications. 

mSLA uses an LED array as the light source and an LCD photomask to shape the layer image onto the bottom of the tank. The LCD screen in Phrozen Sonic Mini and Mighty Series printers is rated at 2,000 hours, which means that it requires frequent replacements.

Phrozen offers a more limited selection of materials, especially for professional applications. Functional resins have inferior mechanical, thermal, and creep performance, building parts that are often brittle, dimensionally inaccurate, not functional, or not fitting together. 

Materials are not validated on the printer, which results in more failed prints and overall lower quality. The part may fail during use or simply not meet the specifications and needs to be reprinted or even outsourced. 

Low-cost resins also have strong odors requiring ventilation and may contain more hazardous chemicals.

Phrozen's Premium Slicer doesn't come included with the printer purchase, but costs an additional $299. It offers a more limited set of features and is only available for Windows.

There’s no logging system on the printers, no remote print monitoring, and no online dashboard to manage printers, print jobs, or materials.

低成本树脂打印机的打印成功率通常为 60%－90%，这相当于 Form 4 失败率的 10－30 倍。

这会引发意外故障并导致项目延迟；造成打印失败并导致树脂浪费；致使重新打印并导致产生额外人工成本，以及使用户无法确定按下“打印”后所得到的最终效果。尽管用户可以调整打印机以提高打印成功率，但需要额外花费时间进行实验。

树脂槽很脆弱，覆膜层很容易破损。一旦发生故障，树脂会覆盖并损坏打印机的关键光学表面，需要长时间清理或更换。

Phrozen hardware comes with 3-12 months of limited warranty and there is little or no support provided for customers other than self-service online. Knowledge base is limited and customers often need to rely on community forums to debug their printers. 

Phrozen's Sonic Mini printers start at $349 while the Sonic Mighty Series start at $649. This doesn't include software, but Phrozen's Premium Slicer is available for $299. Manual washing and curing kit is also available for an additional $199. No option for professional service.

*Low-cost resin printing comes with hidden costs, mainly much higher labor costs due to the lower reliability and complex workflow. If you're planning to use 3D printing for your business, the Form 3+ will become more cost-effective than a low-cost resin printer in a few months of operation while delivering better part performance and fewer headaches.

Phrozen is an emerging company founded by 3D printing enthusiasts that develops resin 3D printers predominantly for hobbyist and personal use.
