The tremendous explosion turned ground materials into liquid, blasting the melted material into the sky.

At the scene, investigators also discovered melted material that appeared to be duct tape, the affidavit said.

As described by 3D Hubs, FDM printers build objects by selectively depositing melted material layer-by-layer along a predetermined path.

The melted material then rises to the surface and forms a volcano--in this case, the Aleutian Arc.

A remote operated robot takes the first pictures of the melted core of reactor 3. Some melted material hangs from the control-rod insertion mechanism under the pressure vessel, and there are piles of rocky objects at the bottom of the PCV that are thought to be melted core.

The coiled PLA filament is pulled into the machine via a tube and then heated up by the extruder, causing the PLA to melt. This melted material forms the model's layers, which is applied in approximately .02 - 1 millimeter layers. The model is built up until it is finished.

Weld strength is provided by entanglement of the diffused plastic molecules. The necessary welding pressure depends on the melt viscosity and wall thickness of the parts and usually ranges between 0.025 and 0.05 MPa. This pressure is maintained while the melted material cools and resolidifies. During this, some plasticized material in the weld zone is squeezed out, forming flash.

The heating time determines the melt layer thickness. Too thick a melt results in excess flash and unfavorable molecular orientation at the joint interface. Too thin a melt produces a brittle weld. The change-over time determines the temperature of the melted material as welding begins and, therefore, should be as short as possible to minimize surface cooling.

In Hot-melt extrusion, the extrusion head heats the food material slightly above the material's melting point. The melted material is then extruded from the head and then solidifies soon thereafter. This allows the material to be easily manipulated into the desired form or model. Foods such as chocolate are used in this technique because of its ability to melt and solidify quickly.

Depending on the composition of the melted material, this volcano could contain a variety of gases. Most of the gases emitted via volcanic eruption are greenhouse gases and cause atmospheric alterations. These atmospheric alterations then force the climate, both regionally and locally, to reach a new equilibrium with the new atmosphere. These changes can reflect as cooling, warming, higher precipitation rates and many others.

At the southern end of Loch Ewe it is only 5–6 metres thick, while at Bac an Leth Choin, southwest of Loch Ewe across the Loch Maree Fault, it reaches more than 30 metres. The unit contains clasts of melted material, although these are unevenly distributed through the sequence. Clasts derived from the Lewisian complex are locally common and samples have been taken to establish which terrane within the Lewisian the samples came from based on their geochemistry.

Pressure is maintained either at a minimum to keep the parts and the hot plate in contact or at zero with a preset displacement. The melt surface reaches approximately 20 °C below the temperature of the hot plate. The viscosity of the melted material can be controlled through the temperature of the hot plate and the heating time. The surface of hot plate is often coated with PTFE to stop the molten plastic from sticking, which limits the hot plate temperature to 270 °C.

Suevite is thought to form in and around impact craters by the sintering of molten fragments together with unmelted clasts of the country rock. Rocks formed from more completely melted material found in the crater floor are known as tagamites. Suevite is distinct from the pseudotachylite in an impact structure as the latter is thought to have formed by frictional effects within the crater floor and below the crater during the initial compression phase of the impact and the subsequent formation of the central uplift.French, B.M. 1998.

The method (often referred to as the KY method) was proposed in 1926 as continuation of the Czochralski and Verneuil methods due to their basic dimensional limitations of grown crystals. Initially it was used to grow mono- crystals of alkali metal halides. The process of direct crystallization of melted material differed by decreasing the boule's temperature while still in the crucible. Compared to others the technique allowed to produce very large single crystals that were free of cracks and damage due to restricted containment.

Nuclear fuel is reported to have melted and fallen to the lower containment sections of reactors 1, 2 and 3. The melted material is not expected to breach a container (which might cause a massive radiation release). Instead, the melted fuel is thought to have dispersed fairly uniformly across the lower portions of the containers of the three reactors, which would make the resumption of the fission process, to the extent of a recriticality accident, 'most unlikely'; however, it is only during future dismantling of the three damaged reactors that it would be possible to verify this hypothesis and to know what really occurred inside the reactor cores.

This toolpath is then followed by a mechanical system to produce the desired geometry. A popular application is stereolithography (SLA), which involves the use of a UV light or laser beam on a surface to create a layer, which are then lowered into a tank so that a new layer can be formed on top. Another commonly used method is fused deposition modeling (FDM), in which a moving head creates a layer by melting the model material (usually a polymer) and extrudes the melted material onto a surface. Other methods such as selective laser sintering (SLS) are also used in the additive manufacturing of 3D microstructures.

Through subduction, oceanic crust and lithosphere returns to the convecting mantle. Areas of the crust where new crust is created are called divergent boundaries, those where it is brought back into the Earth are convergent boundaries and those where plates slide past each other, but no new lithospheric material is created or destroyed, are referred to as transform (or conservative) boundaries Earthquakes result from the movement of the lithospheric plates, and they often occur near convergent boundaries where parts of the crust are forced into the earth as part of subduction. Volcanoes result primarily from the melting of subducted crust material. Crust material that is forced into the asthenosphere melts, and some portion of the melted material becomes light enough to rise to the surface—giving birth to volcanoes.

The first is obtained through a convergent radiation beam which vaporizes the material underneath and pressurized gas to remove the volatile particles and the melted material. The second is based on a high-pressure liquid beam which reaches a velocity of 2.5 times the speed of sound, creating a pressure on the fabric which is higher than the compression resistance of the material and resulting in a net cut. Both these methods have a disadvantage which needs to be considered before choosing the cutting methods: the beams create high- temperature areas along the cut axes, in which the physical characteristics of the material can be altered significantly. During the cutting process, a fundamental parameter to be considered is the nesting layout, as to say the arrangement of the different shapes to be cut in the fabric in order to reduce the scraps.
