Utterslev Skole - Insect

We designed a fantasy insect/animal. The idea was to make an insect who looked like a bird. We drew the parts in InkScape, by using the "circle tool". After the parts are printed, took we a wire and attached it to the insect, so it can be hung from the ceiling.

Utterslev Skole - Spiders And Webs

Our groups name is Utterslev_skole. we made 3 spiders we found on the internet. We found the spiders and the webs on a website named www.thingiverse.com, you search spider or spider web and scroll down and find the spiders and the webs. the webs did we cut in a lasercutter. We have 5 big webs made out of card-board and 4 big webs made out of acrylic. We have 2 small webs made out of card-board and 2 small webs made out of acrylic. We have glued 2 big card-board webs together. We have painted all the card-board webs white.

Utterslev Skole - Workshop for sciencefestival

Our group´s name is 3Dgroup. It´s because we are printing things in 3D. Here today we scaned all people in the group (We are 5) and the pictures looked like 3D in the computer. On friday there is a sciencefestival in Copenhagen. We are going to present our project for allmost our whole school.

Voronoi mønster

Jeg har lavet et mønster som frit kan bruges til dekoration. Jeg bruger den selv til augmented reality tracking ved hjælp af Vuforia, en udvidelse til Unity3D. Hvis du kan kode, så check Vuforia ud (www.vuforia.com). Det er gratis så længe man kun bruger få markers.

Chess board

Purpose: To make a chess board.

Dørskilt graveret i HDF

Dørskilt, graveret i 3mm HDF.

Bare givet en gang klar lak for at dæmpe lugten af brændt træ.
Tegningen er lavet med tegne-plade (Wacom) i programmet Illustrator af mig.

Monteret med dobbeltklæbende tape.

-tak for at vi må bruge laseren.

CD reol i 6mm krydsfiner

Projekt: CD reol.

Materiale: 6mm krydsfiner; det billigste shit fra Silvan.

Konklusion: Lad være.. det er meget nemmere og pænere at bruge en sav. 6mm krydsfiner er alt for ustabilt i formen til det bliver pænt i laseren og man ender med både meget brændte kanter OG ikke skåret igennem i samme stykke.. fordi finéren bare er for uensartet i sin natur.

Resultatet blev dog pænt, og den holder fint CD'er og bøger.. Det havde dog være LANGT hurtigere at skære i hånden. - eneste grund til jeg blev ved var for at teste hvordan 6mm finér opførte sig i laseren.

Indsatser til værktøjskasse

Problem:
Min ven som er VVS'er har varmelægmer løst i en kasse.

Løsning:
Lav holdere til varmelægmerne, så de ikke støder ind i hinanden.

Materiale:
3mm plexiglas, da vand i arbejdssituationen vil gøre træ og pap blødt.

Metode:
Jeg har målt kassen og varmelegmerne og lavet en slags "kam" så der kan være flest muligt.

Program var illustrator, men det kan sagtens laves i inkscape og lignende.
Det hele kan ligge på en 60x40cm 3mm plexiglasplade (akryl) plade.

Boardgame: Fablab Dungeon

Purpose:
To illustrate how to use Defocused laser to speed up outline drawing on tiles and pieces for boardgame prototypes. Estimated time saved is 90% compared to engraving.

Defocusing the laser means you focus the laser and have the surface of your material be lower (in this case 15mm) than the focus point. Then run a vector cut job as if the laser had been focused correctly. You will need alternate settings for the defocused cutting job to get nice results.
