  • This invention is related to fast prototype production with forming layer from molten metal.
  • This invention has designed for provide oppurtunity to make faster production of prototype with shorter production process.
  • Invention involves all layers three dimension designed and also production for being more smooth to produced section. Every layer cuts angular with laser in the manner that forming section that producing edge. Description of Figures
  • Machine's other units operates in coordination under computer control for forming layers sensitively.
  • rollers(41) 0.1 second later after molten metal running from induction furnace and passes with 20 cm/second through molten metal rollers in the needed layer thickness. Unit(l) that lays with same fast to working ground. Material that passes thinned through rollers cools rapidly. When failed to working area groun,material is 1400-1480 degree.
  • Iron atoms are in equilibrium in 1400 degree. When they come into equilibrium,atoms form various forms between each other.
  • Spreaded material(41) connects with previous layer that heating to 1400-1800 degree with the graphite resistance heaters. Molten metal(41) that enough to forming desired thickness layer pours to working area then cuts off the flowing materia(41 ) from induction furnace and rollers(16) stop.
  • Zr02 zirconium dioxide
  • Rollers(16) are made of tungsten and (Zr02) is covered.
  • the controllable distance of roller allows changing thickness of material that spread out. Measurements by changing the thickness of the layers as well as some part of the production to full fasten is very important for securing and errorless.
  • Roller feet (37) are fasten to melting and forming layer unit(l) with one part(38) in one side .
  • the unit to form molten layer proceeds with a carrier(5) and laying material and cooling is done firstly. Cool ing is done in returning of of the unit. Cooling procedure is done with cooling units(8) which blow cool nitrogen gas with a hosepipe. Proceeding speed in the returning of the unit(l) can change according to layer thickness which is cooled and heat.
  • graphite resistance heaters(32) After laying material, graphite resistance heaters(32)close in order when the work finishes but it prevent cooling procedure in returning because of being hot. For this reason, the heat of resistance (32)is prevented with cold nitrogen gas blower (33) in returning of the unit(l ). Heaters(32) work again in laser cutting prodecure. Layer heat is reduced as to 150 degree by cooling. In course of laying, layer is corrected and cooled by layer correction and cooling cylinder (34)60 mm size and 450mm long on the left left side of unit(l).
  • production part platform (28) After every layer which is formed with software is formed in needed thinkness and is cooled, production part platform (28) it is gone down to layer thickness by hydrolic system(24) under the contol of computer(42).
  • nano-ceramic film application unit(3) and heat-resistant ceramic film are applied to the next layer which will be laid and to contact point (12) if supporting material(23) has contact points.
  • ceramic film layer is formed and the part (14) and the supporting material is seperated. Water -soluble nano-composite ceramic material is used for this procedure.
  • 1200dpi print heads (1 1) are used for nano-ceramic film application.
  • Print heads are aligned in double-row form that their working areas will complete each other in Y axis so in every points in working area, nano-ceramic film application can be done twice.
  • heat-resistant nano-ceramic film can be applied in unit(3) reversal.According to the shape of produced part, supporing points(23) and contact points of produced parts(12) can be found at only definite layer. Contact points are defined in different colors with software which forms layer design.
  • Covers(29) are made into machine air-tightly and vacuum unit that is on the machine(43) absorbs the air inside at the beginning and a mixture of nitrogen and hydrogen is applied with fan on the left side(13). During working period, heated nitrogen and hydrogen mixture is absorbed from above.Machine electronic system, laser system, motors and cables are covered with heat-resistance Magnesia(MgO).
  • Machine operation envelope is 600* 37* 370* mm(X,Y,Z).
  • Laying material(41) is done larger areas in X and Y axis.
  • Laying is 800mm long in X axis and it is 450mm in Y axis.
  • the reason to lay lager areas than working areas is to form supporting material(23) also, every working of rollers (16) material flow is irregular and this part is excluded from working area.
  • the amount of the machine production is tied to laser cutting speed. While layer laying and cooling procedure for every layer continues to 20-35seconds, laser cutting process is completed in 60- 150 seconds dependent on the shape of part produced (14).Nano-ceramic film application is completed in 12-17 seconds. In this situation, for 2,5mm layer thickness, machine production amount can change between 9,7cm/hour and 4,4cm/hour.

Abstract

Sur ordinateur, le modèle de section, qui est divisé en couches à l'aide d'un logiciel de création de couches, est lancé pour permettre la conception de chaque section en trois dimensions. Pour permettre de transformer ces modèles en un produit, le métal est fondu dans un four à induction à une température particulière (30). Le métal en fusion (41) est versé entre deux rouleaux de même taille (16), l'un d'eux étant muni de flasques. Lorsque le métal est versé entre les deux rouleaux dont l'écartement peut être réglé, la couche est formée, puis répandue sur la surface de travail et refroidie. Lorsqu'elle est refroidie, la couche est découpée en angle au laser telle qu'elle a été conçue à l'aide du logiciel. Ensuite, pour permettre de séparer les pièces produites de leur matériau support, un film nanocéramique résistant à la chaleur est appliqué en certains points de contact. A chaque fois qu'une couche est formée, la plate-forme de section (28) s'abaisse jusqu'à l'épaisseur de film. Ce procédé permet de réduire le temps de production par la formation de couches plus épaisses et la qualité de la surface de section produite est assurée grâce à la découpe en angle.
