Supports

Properly supported parts are critical to final part accuracy, and print reliability. To properly setup and support the parts, it is recommended to use the SMART SUPPORT feature in 3D Sprint for generation of support structures.  There are several options available to the user for support generation. 

To access the different SMART SUPPORT styles, they can be selected from the drop-down menu:

The different Support Build styles can be selected from the Build Style drop down menu:

Use the table below to select the style in the SMART SUPPORT and Support Build Style that best works for the parts being built:

Support Style: When to Use: Build Length: Cure On Platform:
Lean, Default Support Style Lightweight, Small Parts <24 hours Yes
Lean, Premium Support Style Lightweight, Small to Medium Parts >24 hours Yes
Dense, Default Support Style General Purpose, Medium to Large Parts <24 hours Only if easy access to supports, otherwise remove before curing
Dense, Premium Support Style General Purpose, Medium to Large Parts >24 hours Not Recommended, supports will be very difficult to remove
Flat, Default Support Style Flat oriented parts where supports can be easily accessed with spatulas or cutting tools. <24 hours Not Recommended, unless parts are flat and can use tools to remove support
Flat, Premium Support Style Large, flat oriented parts where supports can be easily accessed with spatulas or cutting tools. >24 hours Yes if parts are flat and can use tools to remove support easily

3D Sprint® is programmed by default to draw the supports twice for the Accura AMX Durable Natural material to increase the stiffness of the structure. Double-drawing the supports adds to the total print time by doubling the support drawing time, but it is required to properly cure the support structures, print taller structures and longer prints (24 hours or more). However, this method is faster and far more effective than increasing the Border Overcure amount for a single draw of the support vectors. The Border Overcure value is how much additional cure depth is added past the current layer. Less Border Overcure means less total cure depth and thus allows for faster draw speeds. These parameters have been optimized and set as default to ensure build success.
