Introduction

This guide will show you a set of common tools we use in the Slicer to streamline the process and to effectively maximize part and print performance.

Part Orientation

The part orientation tool, also called “lay on face” (Hotkey F) lets you select a face of the part to be on the print surface. It will highlight all the available faces, one you click the desired face, it will orientate that face to the bed.

There exists an Auto Orient tool, which typically places the largest face on the part on the bed (not always optimal). This tool can help speed things up when you have many parts.

Supports

The Support Painting (Hotkey L) tool lets you highlight areas of the part that you want to support. You can add supporters or support blockers from this tool.

In the tool window, we typically use the fill tool with “On overhangs only” selected and the smart fill angle set to 40. This lets you quickly highlight faces to support that are over 40° that may be prone to drooping.

In the example below, the green highlighted faces are selected to receive supports, the red faces will not be supported, and the off-blue face is the face on the bed.

After Slicing we can confirm the support structure looks adequate. By default we have tree or organic supports.

Part Arrangement

When importing many parts onto a bed, a useful tool to arrange the parts is using the Arrange All Objects tool (Auto Arrange) (Hotkey A).

It has a few setting you can manipulate to effectively arrange the parts. Default spacing is typically 10mm which is fine for most prints. When filling the bed with parts and maximizing on the build volume, you can reduce this.

Part Clone and New Instance

When creating copies of part it is important to distinguish between a clone/copy and a new instance of the part. We tend to use new instance instead of a clone or copy as the modifications to the parent part are transferred to each instance.

In the Process tab, if set to “Objects”, you can see which are clones or copies, and which are new instances. In the picture below, the bed has three parts, two instances and one copy. Any modifications you make to Instance 1 will be replicated on Instance 2 but not on the clone/copy, and vise versa.

We highly recommend using instances of parts rather than clones/copies.

Process Modifications

The print process is what defines the result of the slicer. This is where you fine-tune the slicer to maximize the performance of your parts. We have tuned the default settings to be effectively for most applications. If changes are required to fit your needs, the defaults will be an effective starting point.

It is also important to understand that changes to the process can be performed on a part-to-part basis if you toggle to “Objects” from “Global”

Quality Settings

There are not many settings in the Quality Tab that we change from the default.

Strength Settings

Settings in this tab that we tend to often adjust are the wall loops (perimeters), top shell layers, bottom shell layers, infill density and infill pattern. Increase to get heavier and stronger parts, decrease to get lighter and weaker parts.

Speed Settings

There are not many settings in the Speed Tab that we change from the default.

Support Settings

In the support tab, settings we tend to use often are the type of support, and to have to supports restricted to be on the build-plate only.

Snug and grid support structures are favorable when print time is a concern. Tree or organic supports use less filament but take longer to print.

Forcing the supports to be restricted to the build-plate means it will not try to generate support structures beginning on the part which can lead to blemishes.

Other Settings

In the “Others” tab, generally the only setting we use is the Brim for tall parts with low contact with the bed.

Cut Tool

The Cut tool can be helpful for parts that are too large for the build volume and need to be broken up into multiple parts. In general we would design these parts in CAD to fit the build volume or perform the split in CAD.
