Prusa released its first public preview of PrusaSlicer 3.0 on September 1. The announcement describes a rebuilt interface and a project system that gives individual print beds their own settings, including the ability to use different printer profiles within one project. Read Prusa's preview announcement.
The changes to watch
Prusa highlights multiple projects in tabs, local recovery backups, and a contextual settings panel. It also describes a revised profile system for printers with multiple tools. These are changes to how print jobs are organized and prepared, rather than a promise that every model will print better.
The September release was explicitly presented as unfinished preview software. Prusa also notes that when a 3.x project is opened in 2.x, geometry can load while settings are discarded. Check the current release notes before moving an established workflow.
Why terrain makers might care
Our take: a tabletop scenery project often has several different jobs hidden inside it. You might want a building shell, a roof, and a handful of small details, each with its own preparation decisions. Keeping those parts organized together could make it easier to return to a project later and understand what belongs where.
A useful evaluation would be a familiar, modest project. Can you find the settings you use most? Can you distinguish each bed's purpose at a glance? Does reopening the project make the next step obvious? Those questions matter more to a hobby routine than the number of new buttons.
We haven't tested this preview. This post covers the announced direction of the software, with project organization as the point that interests us most. For downloads and the latest status, start with Prusa's official page.
