Sinterit Lisa Pro 3D Printer In-Depth Review

Before discussing the insights of Sinterit Lisa Pro, let's briefly touch on the 3D printing technology it's based on - Selective Laser Sintering (SLS). Unlike Fused Deposition Modeling (FDM), SLS wasn't as popular until the mid-1980s due to long-standing patents and its high cost.

In 2014, Polish 3D manufacturer Sinterit introduced the Sinterit Lisa Pro, a desktop-sized SLS 3D printer, which is a rarity in the field of SLS technology. Despite competition from companies like Formlabs, the Sinterit Lisa Pro has been able to provide unparalleled satisfaction to users.

The Sinterit Lisa Pro has undergone several iterations, with the first being a plug-and-play SLS printer capable of producing functional parts and prototypes. SLS differs from FDM as it uses sintering of powdered materials to form a 3D model, resulting in smoother finishes than FDM. The updated version of the printer has a larger build volume, nitrogen chamber, and other added features based on feedback from the first version.

This article will highlight the features, specifications, print quality, and other aspects of the Sinterit Lisa Pro, serving as a guide for comparison with other printers in the same price range.

Features

The goal of Sinterit Lisa Pro is to offer significant upgrades over its predecessor and make SLS 3D printing technology more accessible and affordable, potentially shifting preferences away from FDM 3D printing technology. The company has achieved this by increasing the build volume and introducing a nitrogen chamber, allowing for a wider range of industrial-grade 3D powders. With SLS technology, there is no need for support structures, making it more efficient than FDM or SLA 3D printing. The printer also features a touchscreen interface and Wi-fi connectivity with an onboard camera, allowing for remote monitoring of the printing process. The nitrogen chamber allows for printing with multiple materials, making it more appealing to manufacturers than FDM printers. The accompanying Sinterit Studio 2019 software is user-friendly and offers an intuitive way to prepare 3D models for printing, with a trackable print status and collision detection. The software has been updated for advanced performance based on previous reviews.

Specifications

The 3D printing material used with the Sinterit Lisa Pro must have a powder diameter between 20 to 100 microns, and the minimum recommended wall thickness is 0.8 mm. The build volume of the printer is 90 mm x 130 mm x 230 mm when using PA powder, and 110 mm x 150 mm x 245 mm when using TPU and TPE. The printer measures 690 mm x 500 mm x 880 mm and weighs 90 kilograms. It uses SLS 3D printing technology and a 5-watt laser diode with a wavelength of 808 nanometers to cure powdered particles into parts or prototypes. The XY accuracy is 50 microns and the Z-axis accuracy is between 0.075 to 0.175 millimeters. The printer has a 7-inch colored LCD screen for communication and an on-board camera for monitoring. It can be connected to devices via Wi-Fi or a USB port.

First Impressions

The Sinterit Lisa Pro 3D printer has an industrial-standard build and features a seven-inch touchscreen interface for operation and monitoring. Its sturdy construction leads to reduced vibration during printing, and it has a larger build volume compared to its predecessor. The XY gantry, print bed, and source bed are designed for world-class performance. The printer comes fully assembled and is easy to set up with the help of a manual and online resources. The manufacturer offers support and there are videos available to assist with the setup process.
