Curv3s, new/update design tool

Curv3s is an update for Lin3s.

The main different in between this two is that Curves, does have the ability to draw Bezier curves. This means mainly more organic shapes.

A few parameters have changed their names. Also the parameters has been divided into three groups Design, Effects and Printing. Hopefully this makes it more easy to use.

Now if the line is closed (shift + c), the nozzle follows an spiral motion with z-axis increments per segments. This means no big z movements while printing with a closed line. This is known as spiral vase in Slic3r.

If you decide to print an open line, it will go back and forth changing printing direction on each layer(always printing). Please notice that if paste is not thick enough it is quite difficult to hold a not connected end of line.

Another cool featured added is support for extruder based printers. What makes Curv3s compatible with filament printers. We run some tests and it worked. But I think there is plenty of better tools for plastic, still is fun and fast.

Curv3s is and experimental tool. It generates a LOT of segments for a Curvy GCode. We tried to finetune it to reduce segments without decreasing the smoothness of the path. This requires more work and experimentation . Meaning that sometimes the amount of data send to the printer is too big so the printer stutters for a while.

How to use it:

  • To draw, just click on theplace where you want your new line joints to be (starts drawing the line with the second joint). If you drag your mouse after clicking you would be able to edit the bezier joint handles (paired).
  • To move around a line joint, click on and drag it to the new position.
  • To select a joint, click on it.
  • To edit a bezier curve handler joint, joint needs to be previously selected. Click on and drag the handler point and modify the curve (independent handlers edition).
  • To add a new joint to your line, click on it.
  • To remove a line joint, hold shift and click on the line joint.
  • To close a line, click shift + “c”.
  • To open a line, click shift + “o”.

Parameters:

  • Height (z) [mm]: This param is the total height of the figure.

  • Scale [%]: Total scale percentage between the base and figure’s top.

  • Layer height [mm]: Layer height.
  • Material diameter[mm]: This is equivalent to filament diameter for regular printers. And would be equal to the inside diameter of a syringe based extruder.

Curv3s, even if it has a different name still use Lin3s repository. (Yes, being too lazy to change it :))

Hopefully this new and simplified tool help us to bring easier ways to print food, and a nicer dinning experience.

Manuel Gentili on 3D Food Printing Bussiness Development

Time to time we get some cool emails from people whom, like us, is interested in 3D Food Printing. This time Manuel Gentili give us his thoughts on 3d food printing bussiness development. What is you opinion?

Hi Luis,

first of all thank you for your time, surely your opinion will help me.
In a nutshell, both in B2B and in B2C, 3DFP could be a profitable business. Chef, confectioners and makers at the moment represents the target for the companies, the early adopters of the technology in the food field. New products and services can arise around food printing, think about the sales of cartridges or shops that sales takeaway food. But nowadays, in my opinion, firms have to focus on understanding the needs that can leads to a mass adoption, obviously technology will improve but without a need to supply there is not market. I believe that customization is not enough. 
The current threats are represented in a lack of knowledge of future competitors; in a market not well defined and specially in future laws that may counteract new business. Sustainability of the business is also important, nowadays every business must be sustainable to survive in the market and sustainability can also generate economic benefits. Food and bioprinting could represent a great challenge in the current context, with scarcity of resource and population growth. Internet will provide a great help to 3DFP; companies could use it to create awareness, to promote and sales their product and to develop the CRM strategy.
So I think that the B2B sector is more attractive than B2C, but certainly 3D printing is revolutionizing many areas and the same will happen in food industry.
That is all.
Manuel.

4 human challenges for 3D food printing

Quite a few times we’ve  been asked about the challenges currently facing 3D Food Printing (3DFP).  In order to address some of these issues, we introduce our thoughts about the 4 human challenges for 3D food printing  in the near future.

Star Trek effect

The Replicator from Star Trek is a great concept that is truley mindblowing, but also a very misleading concept. There is a large amount of people that mentally visualize 3DFP as the infamous Star Trek Replicator or that it  should be.

3DFP as we know it today, and probably for a few years, is nothing more than a new kitchen tool (an awesome one) that can explore new creative ways for cooking. Understanding the difference, specifically for Chefs and cooks, will help to embrace this technology at a faster pace for the right use.
