Material testing

 

Are you looking for a material testing service, to carry out a feasibility study or to develop a new material? Work with our materials specialists who challenge the traditional materials to innovate based on your application needs. Ricoh has state-of-the-art test equipment, making us unique in the AM industry, with the ability to precisely test material characteristics and advance your additive manufacturing processes. Some of the equipment and testing we have on offer is listed below or contact us to visit our labs and discuss your requirements.

 

DSC

Differential Scanning Calorimetry (DSC) measures temperatures and heat flows associated with thermal transitions in a material. This thermoanalytical technique allows you to characterize the melting and crystallization transitions of your materials according to ISO 11357-3 or ASTM D3418 standards.

Our TA Instrument Discovery DSC 25 Auto equipment provides superior accuracy in

baseline flatness, sensitivity, resolution, reproducibility, and reliability. Our machine can operate in a calibrated temperature range between -40°C and 400°C.

 

Powder flowability

Powder flow characterization plays a critical role in supporting powder bed fusion processes, as it’s of paramount importance in identifying the powder properties that lead to uniform, repeatable performance.

We are equipped with a Freeman Technologies FT4 Powder Rheometer® which has the ability to measure dynamic flow properties, as well as bulk properties like compressibility, permeability, and density. The instrument also includes a shear cell accessory which allows the powder’s shear properties to be accurately quantified.

 

Particle size distribution

We can measure the particle size distribution of any powder with our Mastersizer 2000 particle size analyser, which uses laser diffraction technology. This technique is relatively fast and can be performed on very small samples, providing a continuous measurement for analysing process streams.

 

Melt volume rate

Melt Flow Rate (MFR) measures the rate of thermoplastic extrusion through an orifice at a prescribed temperature and load; providing a means of recording the flow of a melted material.

We are equipped with a Tinius Olsen MP1200 Melt Flow Index analyser, which generates measurement in accordance with the ISO standard 1133 Procedure A (ASTM D1238 Procedure A) for MFR and ISO standard 1133 Procedure B (ASTM D1238 Procedure B) for determination of MVR.

 

Print test

Using our desktop selective laser sintering (SLS) printer, equipped with a 14W CO2 laser and a maximum operating temperature of 210°C, our team can assist you in evaluating the suitability and performance of new polymer powders. Our printer has a powder bed size of 100 X 100 X 100 mm, requiring only 300 grams of powder to begin testing, and a building speed which can reach 25 mm/h.
