Discovery Hybrid Rheometer (Discovery HR-2)
(TA Instruments New Castle, DE)
The Discovery Hybrid Rheometer (DHR) can make both viscosity and viscoeleastic measurements. The DHR has the capacity to measure both a fluid’s resistance to flow and how it behaves before flowing. Even further, the Discovery HR-2 achieves this with some of the highest precision and sensitivity in the field. Rheometers characterize fluids and solids in terms of flow and deformation. These measurements are useful for a wide range of chemical industries including polymers and solvents, food and agriculture, oil and petroleum and many others. When a material is neither completely solid nor completely liquid, it’s called viscoelastic. Viscoelastic properties like complex modulus and phase angle are measured by rheometers, and they help determine these solid or liquid-like characteristics. They measure the stiffness or toughness of a material as well as its pourability. These properties often come into play when materials have the same viscosity but behave differently. They help characterize these differences and can aid in product formulation to quality control and assurance.
Axial inductive coupled plasma atomic adsorption system for solution composition (Thermal-Jarrel Ash)
Sequential ICP that uses a Photo multiplier tube. It measure light via photons generated by various elements. Their application fields include elemental analysis for quality control, ultra-trace element determination such as for environmental water quality monitoring, and major element determination such as for composition determination. (only uses solution samples; with a resolution of several ppm)

Hysitron TI 950 Tribo indenter
Nano Indenter is used to probe the surface of a sample, generating a 3D map of the surface, and monitoring the effects of the indenter on the material surface. The instrument allows for the studying of strain rate sensitivity on the described above parameters.
Contact Angle
Optical system device, with automatic dosing unit and software for contact angle measure (both static and dynamic) between liquids and solids. Also suitable for calculate solid surface free energy and liquid interfacial tension (drop–slope method). The equipment allows dispersive polar contribution determination, as well as acid-base contribution, surface energy and interfacial tension.
TA SDT Q600(TGA/DSC)
The Q600 provides simultaneous measurement of weight change (TGA) and true differential heat flow (DSC) on the same sample from ambient to 1,500 ˚C. It features a field-proven horizontal dual beam design with automatic beam growth compensation, and the ability to analyze two TGA samples simultaneously. DSC heat flow data is dynamically normalized using the instantaneous sample weight at any given temperature

Custom Built 3D Printer
(3D Inks, LLC, Tulsa, OK)
Solid free-form fabrication, robocasting, is a method by which a structure can be printed without the need for a mold. This printer has the capability to print a variety of materials such as ceramic pastes (HA, β-TCP, Alumina, Zirconia, etc.) hydrogels, or silicone. By using this method porosity control can be easily achieved and the desired compactness of the object maintained. Many different materials can be used but the device is intended to work mainly with ceramic and composite polymer-ceramic pastes.
FDM 3D Printer – Builder Premium
(Builder 3D Printers B.V., The Netherlands)
The Builder 3D printer prints using the "FDM-technique," a 3D printing technique that prints layers of melted plastic filament to ultimately create a 3D model. This particular printer model, Builder Premium (The Netherlands), is equipped with a unique Dual-Feed Extruder to allow for the mixing of to different colored plastic filaments. The printer gives users the ability to print prototype designs and models (STL, OBJ, AMF files), using the program CURA to convert files into G-code, in PET, PLA, and PVA materials. The print area is 205 x 215 x 600 mm (LxWxH), print resolution of 0.05 – 0.3 mm and print speeds of 10 – 80 mm/s.
SLA 3D PRINTER – Form 2
(Formlabs Inc, Somerville, MA)
The Form 2 uses stereolithography (SLA) printing process with resolution ranging from 25 – 200 microns and print dimensions of 145 x145 x 175 mm (LxWxH). This printer has the capability to print with standard and biocompatible resins, which enables the user to fabricate a broad set of print outs for various applications. The printer's software, Preform, has the ability to work with STL or OBJ files.
Ultimaker 3 Extended
(Ultimaker B.V., The Netherlands)
The Ultimaker 3 uses an FDM printing process with resolutions ranging from 200 to 20 microns and print dimensions of 215 x 215 x 300 mm (LxWxH). It is the newest large-format 3D printer from Ultimaker, with dual extrusion capability for multi-material prints. It is compatible with premium materials (PLA, ABS, PVA, CPE, PP, PC, Nylon) used in construction. It features a heated bed which smooths prints and allows for ABS printing. The Ultimaker’s new innovative Print Core system allows for simple swapping of hot ends. This new printer has the capability to use water soluble support filaments to allow for smooth surfaces and complex geometry.
