摘要： Improved apparatus and methods for forming a layer of material over a surface of a previously-formed cross-section of a three-dimensional object in anticipation of forming a next cross-section of the object out of the layer. A volume of material, including at least some excess material, is placed over the surface, and the excess material is swept off by placing the excess material in the predetermined path of a sweeping member, the path being substantially in a plane spaced from a working surface of material. The member may be directed to sweep the excess material away through a successive number of sweeps, which may vary for each cross-section, at least a velocity which may vary for each sweep. Additionally, the clearance between the member and the surface of the previous cross-section may vary for each sweep. A "winged" member is also provided, comprising two legs extending from a base, and a "Trident" embodiment is also provided, comprising three legs extending from a base.

摘要： Apparatus and methods for stereolithographically forming a three-dimensional object includes a vessel for holding a building material and a smoothing member for forming a uniform coating over a previously formed layer of the object. The smoothing member has a plurality of blades. The smoothing member is swept over a previously formed layer of the object, in at least two directions. Different clearances between the lower surface of the smoothing member and the upper surface of the previously formed layer are used to provide a uniform coating for a subsequent layer over the previously formed layer. The sweeping velocity of the smoothing member can be varied. Retractable needles are attached to the smoothing member for adjusting a blade gap between the lower surface of the smoothing member and the surface of the building material.

摘要： A stereolithographic device and method including a process module, a control module and a service module. A laser is employed through a dynamic mirror system controlled by the control module to generate solidified cross sections of a selected part design on the surface of a photocurable polymer liquid. By lowering cured cross sections into the vat, additional cross sections can be perpared and joined therewith to define a prototype product. A stationary mirror in the beam path between the dynamic mirror system and the photocurable polymer is employed to make the system more compact and practical. A calibration and normalization process provides correction to distortions and misalignment of the stationary mirror.

摘要： A plant supporting device and method of utilization thereof which provide proper support and light-orientation of non-ligneous plant members without the necessity of ties, strings, or the like. The device comprises an integral structure made of a homogeneous corrosion-resistant relatively rigid material and includes a pair of arms, a substantially linear ground engaging support with a tapered, rounded end, and a transition between the support and arms. The arms and junction therebetween are disposed in a common plane, and the transition is disposed so that the common plane makes an acute angle with the support. The acute angle is preferably about 20.degree.. The arms, junction, and transition are Y-shaped, and the plant member to be supported is disposed between the arms during use.
