Abstract

A device deposits and fuses the layers of continuous sheets of substance of a selected shape on top of each other such that the continuous body (2a, 2b) is built in a building direction. The feeding device (3) is arranged to grasp part of the continuous body and feeds in a direction opposite to the building direction. The holder is arranged to be received in the feeding device.

Description

529 708 hur höga eller långa objekt som helst kan produceras. 529 708 no matter how tall or long objects can be produced.

Ett fórdelaktig sätt att producera kroppar med B-d-skrivaren är att under produktionen av ett önskat objekt därtill låta den producera en hållardel som är anordnad att mottas i mataranordningen.An advantageous way of producing bodies with the B-d printer is that during the production of a desired object therefor it allows it to produce a holder part which is arranged to be received in the feeding device.

Vid uppstart av processen kan 3-d-skrivaren starta med att på vanligt sätt i ett tråg producera en kropp som matardelen kan gripa om eller så kan processen starta från en i förväg tillgänglig startkropp.When starting the process, the 3-d printer can start by producing a body in a trough in the usual way that the feeder part can grip or the process can start from a pre-available starting body.

Uppfinningen avser därtill en metod för produktion av tredimensionella objekt som utnyttjar en sådan mataningsanordning.The invention also relates to a method for the production of three-dimensional objects which utilize such a feeding device.

Kort beskrivning av figurerna F ig. l visar en utföringsform av uppfinningen Beskrivning av en ßredragen ntfóringsform Med en 3-d-skrivare enligt uppfirmingen påbörjas processen med att ett tunt skikt av pulver läggs på en bottenplatta och delar av skiktet sintras ihop. Ett nytt skikt läggs på det gamla, delar av detta sintras ihop och sintras i den processen även ihop med det gamla skiktet. Processen upprepas på bottenplattan till en viss höjd nåtts.Brief description of the figures F ig. 1 shows an embodiment of the invention Description of an extended embodiment With a 3-d printer according to the invention, the process begins with a thin layer of powder being laid on a base plate and parts of the layer being sintered together. A new layer is laid on the old, parts of this are sintered together and in that process also sintered together with the old layer. The process is repeated on the base plate until a certain height is reached.

I processen sintras del det objekt fram som önskas och samtidigt sintras lämpligen en hållardel fram som genom sintringsprocessen är ansluten till det önskade objektet. Hållardelen är därtill anordnad så att en mataranordning (3) kan gripa tag om hållardelen och mata demia med det önskade objektet nedåt.In the process, part of the object is sintered forward as desired and at the same time a holder part is sintered forward which is connected to the desired object through the sintering process. The holder part is arranged therefor so that a feeding device (3) can grip the holder part and feed it with the desired object downwards.

I fig. 1 har 3-d-skrivarprocessen nått detta stadiurn där hållardelen (2b) är fullt utbildad och mottas i mataranordningen (3). Det önskade objektet (2a) återfinns inuti hållardelen (2b) och bottenplattan som användes vid processens start är borttaget. Då ett ytterligare skikt ska läggas på, förskjuts hållardelen med det önskade objektet en skikttjocklek nedåt genom matardelens verkan och ett nytt skikt läggs på och sintras, varpå processen upprepas. Med en 3-d-skrivare enligt uppfmingen kan alltså i princip obegränsat höga objekt skapas. i 529 708 I den valda uttöringsformen löper hållardelen genom en öppning i ett plant bord (1), så att efier sänkning av hållardelen kan ett jämntjockt lager pulver läggas över en yta som täcker hela cylindern med hållardel och det önskade objektet. På så sätt kan en valfri form uppnås inom de gränser som sätts av cylindems storlek.I fi g. 1, the 3-d printing process has reached this stage where the holder part (2b) is fully formed and received in the feed device (3). The desired object (2a) is found inside the holder part (2b) and the bottom plate used at the start of the process is removed. When an additional layer is to be applied, the holder part with the desired object is shifted one layer thickness downwards by the action of the feeder part and a new layer is applied and sintered, whereupon the process is repeated. With a 3-d printer according to the invention, thus in principle unlimited high objects can be created. In 529 708 In the selected embodiment, the holder part runs through an opening in a flat table (1), so that after lowering the holder part, an evenly thick layer of powder can be laid over a surface covering the entire cylinder with holder part and the desired object. In this way, an optional shape can be achieved within the limits set by the size of the cylinder.

Självklart kan mataranordningen gripa direkt om det önskade objektet och i så fall behövs ingen hållardel, men detta ställer högre krav på utformningen av mataranordningen och bordet (1).Of course, the feeding device can grip directly on the desired object and in that case no holder part is needed, but this places higher demands on the design of the feeding device and the table (1).

Processen behöver inte alltid påbörjas med att en del som är lämplig att mottas i en mataranordning produceras på en bottenplatta som sedan tas bort, alternativt kan naturligtvis en sådan del finns fárdigsintrad eller helgjuten och processen kan då påbörjas direkt från det steg som illustreras i fig. 1. Även om det generellt är mer opraktiskt, kan skrivaren förstås lägga på skikt sidledes och mata ut kroppen åt sidan eller i vilken riktning som helst. Med S-d-skrivare menas i detta dokumentet inte enbart en anordning för produktion av tredimensionella objekt från pulver genom sintring, utan uppenbart kan tillverkningssättet enligt uppfmningen även appliceras på andra metoder för framtagning av tredimensionella objekt från pulver, geler, etc.The process does not always have to start with a part suitable for receiving in a feeder being produced on a base plate which is then removed, alternatively such a part can of course be pre-sintered or fully cast and the process can then start directly from the step illustrated in fi g. 1. Although it is generally more impractical, the printer can of course lay layers sideways and feed the body to the side or in any direction. By S-d printer is meant in this document not only a device for the production of three-dimensional objects from powder by sintering, but obviously the manufacturing method according to the invention can also be applied to other methods for producing three-dimensional objects from powder, gels, etc.
