Materials and Methodology In this research, the primary materials used were Sulphur-free sugar, black tea, kombucha SCOBY, wheat flour, Butterfly Pea Flower (BPF), and beetroot (BR).
Printability tests, including line and cylinder tests, assessed the extrusion and structural integrity of the printed materials.
By converting these materials into valuable resources, this approach helps reduce waste and promotes a circular economy.
Technical Challenges Material Properties: Ensuring consistent texture and stability of plant-based materials.
FLM, especially with plant-based materials, holds immense potential for the future of food.

A certain depth of Martensite layer is found on the hardened surfaces of both materials by metallographic observation and the hardness values meet the design requirement, which demonstrates the practicability of the new technology.
Orthogonal analysis is proceeded successively for the acquirements of influencing pattern and significance of factors, and comparative study is carried on the hardening effect and feature for the both materials.

As the wax amorphous materials, the temperature has a greater impact on "wax film" surface when the specimen which wasmelts.
A hybrid material surface "gap" is shown in Fig 1.
When the asphalt aggregate ratio is 4.6% greater than the stone, the mixed materials are designed to meet the porosity of less than 3% of the requirements.However, as testing personnel, it is impossible before the test can accurately estimate the porosity range of mix and thus a reasonable choice of test methods is made.
Aggregate ratio within the range of the test method wax seal porosity of 9.32% ~ 3.52%, the porosity of plastic seal method 10.43% ~ 4.03%, which is between dense and open-graded porosity between the 2 levels, which has a significant impacton the performance evaluation materials.

The rock fragmentation process is the interaction process between TBM and rock mass, which is affected by TBM specifications, such as thrust force, cutter tip width and profile, cutter spacing, RPM, and torque, and rock mass properties mainly including rock material strength, rock brittleness, joint spacing and orientation.
The basic elements of the RFPA model can be generalized as follows: (1) by introducing the heterogeneity of rock properties into the model, the RFPA model can simulate the non-linear deformation of a quasi-brittle rock with an ideal brittle constitutive law for the local material; (2)by introducing a reduction of the material parameters after element failure, the RFPA model can simulate strain-softening and discontinue mechanics problems in a continuum mechanics mode; (3) by recording the event-rate of failed elements, the RFPA model can simulate seismicity associated with the progressive fracture process.
