About Project

The 25cm high cartoon mouse model is 3D printed with SLA ABS-like resin and hand-painted. It served as a gift for the client's nephew. Rat in a hat is his favorite character in Bananas in Pyjamas.
In order to decrease the risk of shipping damage, we suggest splitting the tail and body into 2 parts and packaging separately.
The material is suitable for building accurate and high tough parts with improved dimensional stability, and it's easier for post finishing.

Solution

• Step 1: We first examine the model, make sure the dimension is correct and all the details can be printed. To decrease the risk of damage during shipping, we split the model into tail and body, then feed the STL file into a 3D slicer software.
• Step 2: When the process starts, the laser 鈥渄raws鈥� the first layer of the print into the photosensitive resin. Wherever the laser hits, the liquid solidifies. The laser is directed to the appropriate coordinates by a computer-controlled mirror.
• Step 3: After the first layer, the platform is raised according to the layer thickness (typically about 0.1 mm) and the additional resin is allowed to flow below the already-printed portion. The laser then solidifies the next cross-section, and the process is repeated until the whole part is complete. The resin that is not touched by the laser remains in the vat and can be reused.
• Step 4: After finishing the material polymerization, the platform rises out of the tank and the excess resin is drained. At the end of the process, the model is removed from the platform, washed of excess resin, and then placed in a UV oven for final curing. Post-print curing enables objects to reach the highest possible strength and become more stable.
• Step 5: As the model is printed in one piece, it needs proficient painting skills. We clearly color all the parts using matte paints just as the blueprint requires.
