More print and paint
Alone at home :-) Lots of time to spend in the workshop.
When writing this post the printer is printig some windows and doors and when that print is finished a fireplace is prepared. Especially I look forward to see if the windows will print properly. (Two hours from now)
Paint used is Vallejo Model Color. The very first paintjob was done with Humbrol Acrylic. The Vallejo paint is far the best.
Have fun

A small paintjob
I have just tried to paint one of the small chairs.
Paint is not what I like most but learned a few things about painting small. The paint should be thinned very much for example. And stereo vision is also a good thing. The painting was done looking through a one-eyed watchmakers loupe.

The next set of chairs will be printed on small pillars for easy removal from the baseplate.
I have plans and drawings for furniture to be used in a small roombox. The coming weekend is dedicated to small prints.
Have fun

PS: Photo was taken with a smartphone and the watchmakers loupe.

First print
At last. The printer is finished and the first print is made.
The coin is a 1-euro
And the finished printer is here.
Next is to learn about all the parameters of the slicing and control software.

Making thumb screws and progress.
The required chemicals has arrived.
Right two bottles is silicone for the VAT-bottom and the right bottle is the light sensitive resin to make models from.
The VAT was coated today. Now it has to cure for 48hours on a flat surface. If everything goes straight I can try first printing at the end of the week :-)
For holding the VAT to the sliding table I was in need for two thumbscrews. The local hardware store didn't have any in the right size! What to do then?
Simple design was done in Sketchup and then 3D-printed.
And the result:
Yesterday a new garden door came and the carpenter will mount tomorrow.
This is the old garden-door. Hopefully the new door will bring a little more light into our dining room.

The lower case is finished and the projector mounted on a baseplate. The projector will be moved up and down depending on some of the printing parameters. Position will be locked by placing dowels in the rails. A screw for moving was considered, maybe in the next version
Status
For testing measurements I made the build platform from MDF a cheap material to use for testing how all the parts fit together. A new made of plexiglas is on the workbench ready to replace the MDF-version.
What remains now? The easy part, namely wiring the electronics, configuration of software and testing operation without photosensitive resin.

SLA printer progress
A little progress on the SLA 3d-printer. I didn't get much time in the workshop during the Easterholidays :-)
First was testing the slide mechanism. Since this photo wast taken I replaced the wooden rails with rails made from plastic because of lower friction.

Test of slidemechanism
Then the upper case was assembled and rails for z-movement (up-down) mounted.
Top case
To get measurements for the lower case that contains the projector a mockup was setup on the dining table.
TestMockup
From other side
In normal use of the projector is meant for projecting a large image on a wall or screen and that gives a too large image so something must be done. Either modify the projector so it can focus at the close distance that requires opening the projector and removing stops in the lens. I didn't like to do that. So instead I chose to try using my set of close-up lenses.
An (cheap) adapter between the internal thread of the projector lens and the external thread of the close-up lenses is on the way from Ebay. The blue masking tape was just to hold the lens for test.
Back to the drawing board designing the lower box.
Have fun

New 3D printing journey
Technique fascinates me :-) I was unsure if I should make a new blog about this project but then decided to keep this one because the end-product will be miniatures.
During the last years I have made a few 3D-printers. Some better than others but I learned a lot.
The last 3d-printer was made during november 2014. It was an Ultimaker classic and actually that printer was better than all the other designs I previously had built. It is reliable. It make nice prints. Why didn't I make the Ultimaker from the beginning? Well, because my cnc was too small for cutting the panels. After having made a few modifications to the cnc it was possible to cut the ultimaker panels..
When I need a print I just power up the printer and start printing. I have not used the printer for making miniatures, but for making parts for other projects.
Well, I tried once printing a 1:24 Queen Anne chair but as the photo show the finish is not good enough for miniatures (as expected). Looking forward to print the same chair in scale 1:144.
So, What next? Answer is SLA (Stereo Lithography Apparatus)
During the recent years the materials for SLA has been better and cheaper and easier to get.
One of the SLA techniques is based on a liquid resin that cures (hardens) when illuminated by ultraviolet (UV) light. The UV-light can be from a special lowpower laser or from a standard homebio projector.
The SLA printer then works as follows.
The 3d-drawing is sliced in very thin layers (f.ex. 0.01mm) Every single layer is then projected on a thin layer of resin. When the resin is cured the printer moves 0.01mm up and the next layer is illuminated and cured. and so on...
I found a cheap used projector with few hours on the lamp.
Next was to decide how to build the printer. A few hours browsing the net I decided to build something like the B9Creator.
My design is mostly based on materials I have in my junkbox except for the 6mm birch-plywood.
I was happy with the Ultimaker way of assembling sheets of plywood so based on the open source drawings and plans for the B9Creator I made drawings to be cut on my CNC-machine.
An essential part of the printer is called the VAT (I don't know what it stands for but it's not Value Added Tax) The VAT contains the uncured resin.
The plate that holds the object(s) to be printed is lowered into the resin leaving a small cavity between the VAT-bottom and the buildplate (0.01mm high). When the resin is cured the VAT slides away to release the object from the VAT-bottom. The VAT-bottom is covered with a silicone layer that prevents the cured resin to stick to the bottom, The sliding action is a way to overcome the adhesion between the build and the bottom.
Next is to assemble the panels and make bottom half where projector will be mounted. Again I wan't a bigger cnc...

A little technique and a shop sign
I decided to make my shop sign from painted plywood. The sign has to be finished as one of the first things to do in the shop because the danish equivalet to "Tour de France" called "Post Danmark Rundt" passes on the way to the finish line so a lot of people will come and see the bikes (and hopefully my shop :-)
First photoshop layout
On the sidepanels I will place two large QR-codes one pointing to my website and another pointing to facebook.
I don't have a cnc that big so handcutting with a scrollsaw is the way to go. For transferring the letters to the plywood I learned this technique from one of the scrollsawers-blogs. First I draw outline of the letter with my cad-program and then print the drawing on a laserprinter. The drawing is then placed with the printed side facing the plywood. Then the paper is soaked with zylene and rubbed with a soft cloth. A photocopied drawing can be used too.
The drawing can be seen through the paper.
And pattern ready for scrool-sawing. The zylene evaporate without any signs on the wood.
I have also used this technique for miniatures for both sawing and carving. Much easier than using transferpaper.
After a few hours scroll-sawing here is the result. Ignore the letters isn't on a straight line :-)
The dots after N and J should be a little larger. Next is a paint job.
And a first floor view of our garden. In the background is another real size project I have promised to finish this week-end. Removing old paint from a door and then repaint and giving some oil to the garden chairs
Have a nice week-end

New journey!
I have started a new journey
In the end of august I will open a brick&mortar shop: N.J.Model&Hobby.
The photo has undergone a little photoshopping. Today the shop sells knitting yarn and fabric.
I'll try to sell nearly everything for making doll's houses. Woods, tools, tapestry, furniture, glue, paint, etc....
Progress of the shop will be published on Facebook. I'm told that is the way to spread the words :-)
Here is the link to N.J.Model&Hobby on facebook. Postings on facebook will be in danish only but google translate may be a little helper.
If you wan't to see the surroundings here is a link to google streetview.
Have fun

Spring is coming, time to change horses...
Well, long time since last time I wrote something here...
As headline says spring is coming after a long and cold winter.
I look forward every spring to see those flowers in our garden. They are Anemone nemorosa normally found in the woods but a few has decided to grow in our garden. Yesterday I saw the first bumblebees and a butterfly
The 3D-printing story has ended. The technology is not mature enough yet, maybe in 3 to 5 years.
I know you can buy some small pieces of 3D-printed furniture but the quality is far behind the standards I'm looking for. So all my 3D stuff is dismantled and boxed away. It has been fun and I have learned a lot.
What to look forward to? Well here is a little preview of my current just for fun project.
The steel-balls is 2mm in diameter and the display case is h=32mm, w=39mm and d=32mm. If we translate from 1/12scale to real size that gives hwd=38cm,47cm,38cm.
More to come later.
Have fun

Merry Christmas
3D-printing is fun and takes a lot of time:-)
Here is my latest print plus a little painting afterwards
Same on table for a better view.
The three kings are bringing gifts to new born child. Of course they also have their Camel with them.
And of course the Christmas Crib with the new born child and his parents.
And a Google Sketchup screendump
Have fun
Niels
PS: I am not the designer of the set. I found it on http://www.thingiverse.com a site with lots of ideas of what can be made with a 3D.printer.

The new black
Ever since I heard about 3D-printing many years ago it has been in my mind that someday I would join the wave.
Now it is time for exploring the posibillities of 3D-printing.
I have spent a few hours on the net studying several designs but most of them fails because they are build using 3d-printed components. Chicken and egg problem.
Yes I could go to Ebay and buy a kit but ...
Then I found this Mendel90 design that uses mdf for the basic structure plus (again) lots of 3D-printed plastic parts.By studying the design I soon found out that all the parts can easily be replaced by either wood- or metal-parts.
Basically a 3D-printer is a glue-gun that can be moved in three dimensions so the first challenge is to build a structure for that. The same challenges as for my CNC-machines stable structures with precise movements of a tool..
Here is the very first mockup for my first 3D-printer. A simple T-shabe from two sheets of plywood.
In front of the vertical sheet is some of the parts I will use for the vertical movement of the glue-gun, extruder in 3D-language.
The plywood-sheets is held together with this ingenious "Ikea" screw and nut.
In german the bolt and nut is called "Quermutterbolzen und Rundmuttern". It took me quite a while to find out :-)
Can it be used for miniatures? Maybe.....
3D-printed Queen Anne Chairs in 1:48 scale.
