10 Tips of Using 3D Printer To Print Model
Casey (Kacie Hultgren, PrettySmallThings founder) was a Broadway stage designer, use 3d printer produced some scale models in the design stage, which contains stunning zero zipper bag and purse, she is also the "2014 Ultimate Guide to 3D Printing" one of the book's test team members.

MINGDA staff summarized 10 criteria in the production model for 3D printing , it will be help to the new who just use 3D Printers.



1.45-degree rule

Remember that 45-degree rule. Anything over 45 degrees projection requires additional support material or clever modeling techniques to complete model printing, design your own support or link objects (cones or other supporting material) and places them into the design model.


2. Try to avoid the use of support materials in the design

Although support with algorithms over time has been in progress, but the support material will leave ugly marks on the model after the removal, and the removal process will be very time consuming. Try to design your model without the help of the support material, it can be directly 3D printing.


3. Try to design their own print base

Make good use of the "mouse ears ". "Mouse ear" is a disc-shaped or cone-shaped base design to put them into your model, do not use the software built-in base models. Tony Buser"Mouse Eared Rocket Fincan" and Casey 'Windsor chair "is an excellent example of good use of this design ingenuity. Do not use the built-in print base (raft), it will drag you print speeds, in addition to different software or printer setting, may be difficult to remove the base and damaged the bottom of the model.


4. understand the limits of your printer
Learn the details of your model, is there have some tiny projections or parts are too small and can not use the desktop 3d printer to print it? In your printer, there is a very important but often overlooked variable, that is, the line width (thread width).
Width is determined by printer nozzle diameter , most printers have a diameter of 0.4mm or 0.5mm nozzle. In fact, 3D printer drawn circle and size will be twice of the line width. For example: a 0.4mm nozzle painted circle minimum diameter of 0.8mm, and 0.5mm nozzle painted minimum diameter is 1mm. Like Casey in the film, said the basic principle: "the smallest objects you can create not less than twice the width."

5.Need to choose an appropriate tolerances for the connected spare parts

To have multiple connections at the model design as you see fit tolerances. To find the correct tolerances may be some difficulties, the key to calculate the correct tolerance technique is: where (nip or link objects) require close contact reservation width of 0.2mm; for a more relaxed place (or hub box lid) reserved 0.4mm width. You must personally do tests for models to determine the appropriate tolerances you want to create something.


6. Using the appropriate shell (Shell)

Do not use too much shell on the high accuracy model, such as some tiny models, excess housing make these fine place obscured.


7. Use the line width
To take advantage of the line width as your advantage. If you want to make some may be bent or thinner model, your model will be designed into the thickness of a generous line. You can look at Casey's "Flexible Inspiration" portfolio, which provides many examples of the use of this technology in the Collections Thingiverse on.
8. Adjust the printing direction in order to best accuracy

Always with the best resolution possible direction do you model orientation. If necessary, the model can be cut into several blocks to print, and then re-assembled. For FDM technology printer, you can only control precision Z-axis direction, because precision XY axis line width has been decided, if your model has some fine design, confirm the print orientation of the model's ability to print those fine features.


9. Adjust the direction of the print according to the sources of stress
When the force applied to the model, we want to keep the model will not be destroyed. Make sure you print directions to reduce stress concentration in some areas, we can adjust the print direction perpendicular to the print line at a stress is applied.
The same principle can also be applied on the model used to print large ABS supplies, during printing, these models may be due in large print stage cooling of relations split along the Z-axis direction.

10. The ultimate goal: the right to print and place your model design

Designed to print using the position includes a variety of integrated object is fused deposition printers "ultimate goal." In this a lot of tricks to teach you how to "print your design in place": the design of an object on the printing platform, adjacent link these objects, and carefully printed at intervals.
