Stereolithographic 3D Printing with Renewable Acrylates

Stereolithographic (SLA) 3D printing of oral modified-release dosage forms.

The aim of this work was to evaluate the suitability of stereolithography (SLA) to fabricate drug-loaded tablets with modified-release characteristics. The SLA printer creates solid objects by using a laser beam to photopolymerise monomers. In this work polyethylene glycol diacrylate (PEGDA) was used as a monomer and diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide was used as a photo-initiator....

Printing 3D objects with interlocking parts

Recent advances in 3D printing technologies bring wide range of applications from fast prototyping to product manufacturing. However, one intrinsic limitation of 3D printing is that we cannot fabricate a single object that is larger than the working volume of a 3D printer. To address this issue, we may partition the given object into 3D parts of manageable sizes for printing, and then assemble ...

3d Printing with Natural Fiber Reinforced Filament

An initial study of 3d printing with compound filament using different plastic matrices and sugar cane bagasse as the filler was conducted. In order to do this, a reverse engineering process was made to several 3d printer extruders to determine how to change the extruder in order to be able to print with the filament. To obtain the filament, a plastic extruder was modified to obtain a compound ...

3D Printing with Nucleic Acid Adhesives

By relying on specific DNA:DNA interactions as a "smart glue", we have assembled microparticles into a colloidal gel that can hold its shape. This gel can be extruded with a 3D printer to generate centimeter size objects. We show four aspects of this material: (1) The colloidal gel material holds its shape after extrusion. (2) The connectivity among the particles is controlled by the binding be...
