Simulating Hip Cartilage using 3D-Printed ABS-M30

Check if the same lab product or an alternative is used in the 5 most similar protocols
After a comparative analysis of the materials compatible with the Stratasys FORTUS 250 mc machine, acrylonitrile butadiene styrene M30 (ABS-M30), a synthetic material with similar mechanical properties compared with the cartilage at the level of the adult hip (Table I), was selected (13 (link)). The characteristics of the ABS-M30 material were taken from the datasheet published by Stratasys, Ltd. The characteristics of the hip cartilage were taken from data reported in the literature (1 (link)). Acrylonitrile butadiene styrene (ABS) is a thermoplastic polymer of fossil source obtained through the polymerization of styrene and butadiene in the presence of acrylonitrile, which allows the manufacturing of models using additive manufacturing technology (14 (link),15 (link)).
To simulate the articular cartilage at the level of the femoral head and condyles and to achieve a uniform distribution of the compression forces, the loading was carried out using two 3D-printed parts made on a Stratasys FORTUS 250 mc computer numerical control (CNC) machine (Stratasys, Ltd.) using ABS-M30 (Stratasys, Ltd.).

Chemical Compatibility of Thermoplastics for 3D Printed Lab Components

Check if the same lab product or an alternative is used in the 5 most similar protocols
Thermoplastics were selected for chamber fabrication based on chemical, and auto fluorescence compatibility. Small 5 mm × 5 mm × 2 mm 3D printed sections of PETG (polyethylene terephthalate glycol copolymer), P430 ABS, ABS M30 (Acrylonitrile butadiene styrene), nylon and vero magenta (Stratasys®, Israel) were used for compatibility testing. For chemical compatibility testing printed samples were weighed before and after solvent treatments (at 1 h and 24 h post treatments). The test included the following five solvents at neat concentrations- distilled Milli-Q™ water, acetone (analytical reagent), chloroform (analytical reagent), 2- propanol (analytical reagent), and acetonitrile (HPLC grade); all solvents purchased from Thermofisher Scientific®, Australia. A similar test was conducted against neat concentrations of four surfactants esterified vegetable oil (EVO), fatty acid ethoxylate (FAE), organosilicone (OS), and alcohol alkoxylate (AA) supplied by Victorian Chemical Company®, Australia.

Uniaxial Cyclic Stretching of Hierarchical Scaffolds

Check if the same lab product or an alternative is used in the 5 most similar protocols
The dynamic culture was carried out on two hierarchical scaffolds by using a commercial bioreactor (MCB1, CellScale, CAN). Before each stretching session, the bioreactor was sterilized by washing the test chamber in ethanol 70% (v/v) and sterilized by means UV radiations under a fume hood for an hour. To transmit a uniaxial stretching, the hierarchical scaffolds were hooked between the stainless-steel actuator of the bioreactor and a custom-made 3D printed pin of acrylonitrile butadiene styrene (ABS) (ABS-M30, Stratasys, USA). During each session, the specimens were covered with 150 ml of complete medium and stimulated for 1 hour with 4 mm of displacement (corresponding at a strain of approximately 5%) at a frequency of 1 Hz (3600 cycles).
These parameters were chosen in accordance with the literature (Bosworth et al., 2014) (link).
Each of the two scaffolds was stretched two times during the 7 days of culture (i.e. at day three and day six of culture). After each bioreactor session, the dynamic specimens were put in T25 flasks with 5 ml of medium and left in static conditions for two days.

3D Printed Plastic Model Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
The plastic models were 3D printed from the corresponding STL models according to the methodology of Abel et al. (2010, p. 468) . All three models were printed in black plastic (ABS-M30 or ABA, Stratasys, Eden Prairie, USA). The resultant models comprised layers 178 m thick, discernible by eye, with the layers perpendicular to the long axis of the heads. An aluminium peg was inserted into the back of each model (Fig. 4E, Pe).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
