The use of bed adhesion materials in FDM printing can help parts stick to the plate during printing. What are the two common adhesion material used? (Pick two)

Blue Painter's Tape and Hairspray

If a part is too big for a machine what is the best option to be able to print it.

Cut the model into smaller parts and glue them together after printing

The 3D Printing Process in which a strand of material is pushed through a heated muzzle is known as:

True or False. FDM Printers are only capable of Printing PLA material?

False

True or False. Increasing the number of triangles on an STL file will decrease the overall print time.

True or False. Once a part has completed, the remaining resin in the tank should be discarded because it has been used.

False

True or False. PLA material gives off an odor that is not pleasant to most people

False

True or False. SLA printers are capable of printing different infill percentages.

False

Tue or False. Supports for overhang areas must be molded into the CAD model before sending it to the slicer software.

False

The creation of advanced part structures is aided by what type of CAD design tool?

Generative Design

What is the most common material used in build plates for FDM printers?

Glass

When using PVA as a support material, what is the best way to remove it from the finished part?

In a tank of tap water that has a moving flow

What is the benefit of using NFC Enabled material from Ultimaker?

It allows the machine to know what material and spool size is loaded in the machine

Scaling down a mating part will achieve what?

Make it easier to make that part to another because of the slightly smaller scale

Select the different ways you can send a file to a printer. (Select Multiple)

Over a WiFi network and by using a USB thumb drive

The Ultimaker machines featured on the video utilizes a second nozzle that prints support in PVA. What is the benefit of this procedure?

PVA is a water soluble so the supports can be easily removed.

How should the layers of an FDM printer be oriented relative to a compression load?

Perpendicular

What is the easiest way to achieve a better-quality print?

Reduce the layer height

The 3D Printing Process that uses a lazer to harden liquid resin is known as:

SLA

As a general rule, when the overheating of a part's geometry exceeds a certain angle, the use of what type of feature should be used to achieve a good print.

Support

To ensure the proper adhesion of layers in the FDM process, it's best to monitor the print at what point.

The first 3-5 layers

Sites such as Thingiverse.com or 3DContentCentral.com are useful for 3D Printing in what way?

They host free CAD files that can be 3D Printed

What consideration should be taken when storing unused PLA material?

They should be stored in a dry area

What is the benefit of having a heated build platform in an FDM printer?

To keep the part from cooling and warping

True or False When printing a hollow part in an SLA machine, it is important to ensure there is a drain hole at the bottom of the part based on its printing orientation.

True

True or False. 3DExpert from SOLIDWORKS and 3DSystems is free for anyone using SOLIDWORKS

True

True

True or False. Increasing the quality of the finished part will take the machine longer to print it.

True

True or False. One of the most common materials used in FDM printers is PLA.

True

True or False. Parts printed in UV resin need to post cured

True

True or False. Parts printed in a UV resin can be cured by placing them out in direct sunlight.

True

True or False. Raft must be molded in the CAD model before sending the file to the slicer program.

True

True or False. SOLIDWORKS provides the ability to view overhand areas of a part that might require support structures to be added.

True

True or False. The "One Click Print" feature found in Formlabs Preform software includes the ability to automatically add structure supports where needed.
