Abstract

Three-dimensional (3D) printer is a machine used to generate product in 3D drawing using application such as CATIA. This process is also known as additive manufacturing (AM). 3D printer uses heating process to squeeze out melted filament which used to print a product. In printing process, the filament is printed on a platform which applied with certain type of adhesive. This adhesive act as medium to hold the specimen printed. Many type of adhesive had been used in this process which divided into two part which are synthetic and bio adhesive. The use of bio-based adhesive in 3D printing is starting to grow but there are still flaws in the process. In order to overcome this flaws, many research and investigations that can be carry out in order to study in details the problems occur and how to overcome it. One of the highlight problem in this research is warping deformation which occur during printing process on the first layer of specimen. The vertexes of the specimen tend to warp and cause deflection at the side of the specimen. New mixture of plant-based bio adhesive was invented and experimented with the ability of reducing warping deformation while holding the natural friendly criteria of adhesive. In warping deformation, printing using bio based adhesive resulted lower value of vertexes compared to synthetic adhesive. Aside of producing new mixture of plant-based bio adhesive, the viscosity of the adhesive also been investigate in order to ensure that this mixture is suited to be used in 3D printer application. Provided that a new mixture had been done, comparison between the available adhesive which is UHU glue as synthetic adhesive was made in order to identify which adhesive has the strongest criteria of adhesive. This comparison was done by going through tensile test using Universal Tensile Machine Dynamic 8872. From all the result obtained, it is concluded that synthetic adhesive shows the highest strength for tensile test compared to bio adhesive. In overall result, synthetic adhesive is stronger than bio adhesive.
