New Resin Capable of Creating Both Solid Objects and Dissolvable Supports for 3D Printing

A significant breakthrough in vat photopolymerization 3D printing has been achieved by a collaborative team of scientists from the University of California Santa Barbara and the Lawrence Livermore National Laboratory (LLNL). They have successfully demonstrated a novel resin that possesses a remarkable dual functionality: it can be transformed into either solid structural objects or dissolvable support structures, depending solely on the specific type of light it is exposed to during the printing process. This innovation addresses a long-standing challenge in resin-based 3D printing. Traditionally, when fabricating complex geometries with unsupported features such as overhangs or bridges, solid supports are printed alongside the main object. These supports then require tedious and often damaging manual removal during post-processing, which can be time-consuming, expensive, and sometimes compromises the integrity of the final part.

This revolutionary new resin offers an elegant solution by providing the option to dissolve the supports after printing. The researchers achieved this by combining a base-degradable thermoset – a type of polymer that can be selectively broken down in a basic solution – with the primary structural material within a single, convenient one-pot formulation. The printing process itself utilizes a dual-wavelength negative imaging (DWNI) DLP (Digital Light Processing) printer. The degradable thermoset is precisely solidified using visible light, while the permanent structural material is cured with UV light. Crucially, both types of light can be simultaneously projected using a single digital micromirror device (DMD), allowing for intricate control over which parts of the resin form the main structure and which form the temporary supports. Once the printing is complete, the object undergoes a thermal post-processing step to fully set and strengthen the primary material. Following this, the thermoset supports are simply dissolved away in a basic liquid, leaving behind a clean, complex object with minimal post-processing effort. This pioneering DLP method holds immense potential to significantly broaden the range of 3D printable materials and structures, opening doors for more intricate designs, cleaner parts, and more efficient manufacturing workflows across various industries.
