The first application of computer technology in interior design occurred in the making of design drawing, working drawing, and presentation drawing by using computer software such as AutoCAD since 1982, 3D Max Animation since 2005, Adobe Illustrator since 1986, and Adobe Photoshop since 1990, followed by design softwares for 2D and 3D drawings, such as SketchUp, TurboCad, Revit, Archicad, Infurnia, and Live Home 3D. Computer technology was also used on 3D printing machines to translate the 2D drawings into 3D models, in calculating the energy efficiency on the green designs and in the making of green construction (ConstructionSuite since 1999, Green Wizard, Autodesk Green Building Studio and Greengrade), and to create animated images, moving objects, simulations, and hyperreal spaces utilizing virtual reality. This study reviewed the combination of physical and digital elements in interior design to learn the values of hybrid space created when users experienced the mixture of static stable image and the constantly moving/changing image. The physical space has the temporary, ambiguous, dual coding (physical-digital) characteristics, which in turn generates the problem of representation referred to as Heteropia space by Michel Foucault in 1967.

A dual syringe pump was constructed using 3 D-printed support structures along with a NEMA-17 1:5 gear ratio bipolar stepper motor, an AMIS-30543 micro stepping bipolar stepper motor driver board, and additional hardware. TurboCAD 2016 (IMSI/Design, Novato, CA, USA), a computer-aided design (CAD) software package, was used to design the components and files were saved in stereolithography format files (STL). The STL files were then uploaded to Formlabs Preform software and models were printed by a Formlabs Form 2 Stereolithography Apparatus (SLA) printer (Formlabs, Somerville, MA USA). After printing was completed, the models were soaked in isopropyl alcohol to remove excess resin for 40 minutes and dried under normal laboratory conditions for 2 to 3 hours. Supports were detached from the models and parts were assembled to complete the dual syringe pump (Figure 2).
