In one embodiment, a method of forming an extruded board includes mixing a resin and a foaming agent, melting the mixed resin and foaming agent to form a uniformly colored extrudate, differentially expanding voids formed from the foaming agent within the uniformly colored extrudate by passing the uniformly colored extrudate through a breaker plate, forming a board with the differentially expanded voids and uniformly colored extrudate, and forming lightened portions on an outermost surface of the formed board.

Polymer-based sheet materials having a variegated appearance are provided. The polymer-based-sheet material may have a core with one or more caps. The cap(s) may be on a first primary surface, a second primary surface, and/or sides. The variegation may be within and/or on the cap and/or the core. Methods, systems, articles, and materials effective for a polymer-based sheet material having a variegated appearance are provided.

A three-dimensional shaping method including the steps, after a lamination step, in which steps of forming a powder layer, flattening with a squeegee and sintering are repeated, followed by cutting of the surface of the laminate, 1. setting the overall shape of an object to be shaped by a CAD/CAM system, and setting machining units that form the overall shape and cutting allowances on peripheral sides and upper sides of each of the machining units, 2. cutting of the peripheral sides and upper sides according to a prescribed order, after lamination with addition of a cutting allowance on the peripheral sides of each machining unit, and after carrying out lamination to the thickness of the cutting allowance on the upper side of the machining unit and the machining unit adjacent above the machining unit, and 3. continuing repetition of step 2, from the lowest to the topmost machining unit.

Aspects described herein are directed to compositions, systems, and methods of manufacturing a polymer-based construction material comprising polymeric resin and filler such as calcium carbonate (CaCO.sub.3). A surface of the polymer-based construction material may be treated such that the surface energy is increased from the material's inherent value to a predetermined value of at least 40 dynes/cm.sup.2. Further, the surface energy of the treated surface may persist within 20% of the predetermined value for at least three days.

A composite material is formed by preparing mass particles consisting of a fibrous material at least partially derived from recycled post-consumer materials and preparing particles of a binding material consisting of a thermoplastic material at least partially derived from recycled post-consumer material. The prepared mass particles and particles of binding material are mixed together such that the binding material liquifies and coats the mass particles which are subsequently then pressed together to form a composite article in which the mass particles typically occupy between 35% and 60% by weight of the composite material and the binding material occupies between 40% and 60% by weight of the composite material. The composite material is suitable for replacing concrete, wood, or other construction, manufacturing or industrial materials, and possesses properties that in some applications may be equal or superior such materials.

The method for manufacturing a timepiece component (10) having at least one first portion with at least one functional flank, for transmitting energy to another component or dissipating energy from another component, and at least one second portion with a guide surface,

includes carrying out a first micro-injection (E1) forming a blank (10) of the timepiece component, the blank having the at least one first portion and the at least one functional flank and a blank of the second portion,
then a second machining (E2), particularly a second laser machining, in particular femtosecond laser machining, of at least part of the blank of the timepiece component, this part including the blank of the second portion for forming the second portion with the guide surface.
