While today's 3D printers produce rough workpieces that are sometimes very successful in terms of finishing, post-processing is a necessary step to improve the rendering and obtain more vivid colors. In addition to the aesthetic aspect, painting or varnishing a 3D printing makes it possible to durably protect the room from shocks, temperatures, UV, humidity and other external aggressions. Post-processing is also an opportunity for 3D printer users to express their creativity by bringing an additional degree of customization to their 3D prints.
The beautiful figurines and colored decorative objects shared here and there on the sites and social networks, hide in reality an important finishing work. Several steps of sanding and application of products are necessary to achieve this result. To help you in this discipline full of post-processing, Primante 3D has produced a guide grouping the best finishing products and some cheap tips.
Potted or bombable finishes
Primer is an essential step in post-processing to produce a finished product. It consists of applying a layer of preparation on the plastic (the under layer), after having taken care to carry out a sanding of the part, then a degreasing with soapy water.
Thanks to this operation the support is thus better able to receive the paint by reducing its porosity and increasing its adhesion. It also highlights the areas to be treated, multiplying the sanding with the appropriate grain. Without treatment, the traces left by the layers or the supports would remain visible. It is therefore necessary to fill them to obtain a smooth and perfectly uniform surface.
It is recommended to apply a black base coat for dark shades, and white for light colors. A white undercoat allows for more vivid and vivid paintings, while a black one returns duller colors. The colored primers allow to underlay at one time and to pose the dominant shade. This saves time on uniform paintings.
In the case of cracks, holes or joints, pot-based putty is used as a finishing compound. Automobile brands used in bodywork, such as Ecar for example, give good results and lend themselves well to large areas. Recognized by designers for decades, mastic Tamiya Putty (Basic Type) knows the same success among makers. As its gray color could sometimes complicate the application of a clearer paint, Tamiya now offers it in White. Given the capacity of the tube (32g), it will be reserved rather for smaller size pieces.
We can also find putty to apply with the brush but it is longer and the layer of paint that is left with the brush is thicker. To plug the holes, there is a trick used in model aircraft that consists of making a kind of mortar by mixing talc and cyanoacrylate glue (Super Glue). This technique can also be used to assemble parts. Applied on both sides, the glue filler increases the bonding surface.
For small touch-ups and finishes, an aerosol primer is ideal for painting prints quickly and evenly. Once again Tamiya stands out from the pack. His bombs are unanimously recognized for their very good quality of grip and coverage.
Other value sure, the bombs Citadel from Games Workshop and Army Painter, often praised for their uniform sanding ability and fast drying time. A notch below but more affordable, the primeurs d 'Irontek offers an interesting alternative.
Aerosol or potted paints
Once the primary is dry, the final color can finally be applied to the piece. Acrylic is by far the most used type of paint because it is the one that combines the most qualities: good coverage, good strength and ease of use (because dilutable in water). Once again just look at the figures and models to find the best brands. In this field, whether they are pot or bomb paint, the Citadel ranges from Game Workshop (Citadel Base) have a long history of success. Despite a limited number of hues their hiding power is important.
The Spanish brand Vallejo, which forms a single brand with the French Prince August, offers three main ranges of paint in pots: the Game Color dedicated to figurines fantasy themes and war games, the Model Color formulated to respect plastics and polyesters and Model Air, a range of liquid acrylic colors specially developed for airbrushes. The packaging is a bottle jar of 17 ml which allows to properly dose the paint.
For spray painting, the brand Montana Color well known graffiti artists, the advantage of being very covering while remaining very fluid, which avoids clogging caps. Also used as undercoat, the German brand Molottow offers a very interesting range to make ultra-bright metallic effects in chrome, copper, or gold.
Good brand to start, the acrylic pots ofArmy Painter allows to find a lot of colors, or getting closer to your model. His paintings are particularly famous for his metal which have the advantage of being very liquid and very covering. As the brand also offers primer bombs, some pots are marked "100% color match". This means that the color perfectly matches that of the undercoat bomb.
Varnishes and resins
Once the paint dries, if the result is suitable a last coat of varnish can be applied on the piece. It will protect the piece from the wear of time and give it different aspects, shiny, satin or matte. For the mat, the Games Workshop bomb varnish range gives very good results.
For gloss, we will use rather the varnish pot Prince August or Pebeo. They offer a perfectly stretched film, flexible and indelible, and a very uniform shine. Well known designers, the satin of Humbrol has also proven itself. This solvent-based varnish, applicable to brush or airbrush, becomes clear and transparent to drying. It overcomes the yellowing effect associated with traditional varnishes.
Household products also sometimes have good surprises. Johnson's Klir polish used for floor care is nothing less than a glossy acrylic lacquer. This cheap alternative has long proved its efficiency in model making. You can also use SOL PLUS cans or pliz from JOHNSON who are easier to find. Opinions differ as to whether it is the same product. This product is better known in America under the brand "Future" and EMSOL in Belgium.
The liquid can be applied with a brush or by dipping the pieces squarely into a bath. In case of traces or accumulation, the piece can be recovered using a household cleaner, the Glanzer. This ammonia-based product can also be used to dissolve acrylic paint.
Well known makers of the famous acetone technique to smooth the ABS, at the same time acts as varnish. For other filament like PLA, the resin XTC3D, in addition to smoothing the streaks, also allows to obtain a good gloss. Be careful, however, because it tends to yellow over time, especially when exposed to the sun. This yellowing is even more visible on the light colors. If you want to add color, Mica powder can be added to the clear resin to obtain the desired hue.
Another tip is to use fast-drying PVAc (vinyl glue). Water resistant glues from UHU (fast setting D3) give good results; with smooth and shiny surfaces. To make their metallic prints shine, some makers use another technique of coating their pieces with beeswax.
Here is what you want to know before visiting your regional medical dispensary:You will need a physician’s recommendation, medical cannabis certificate, or whatever proper documentation is required by your condition. Ordinarily, you must be 18 or older to qualify for a medical consent, but exceptions may be made in some states for minors with especially debilitating conditions. You will usually enroll with a medicinal dispensary. This is to keep your medical cannabis recommendation or certification on file for regulatory and legal purposes. There will be a waiting space. This is to control the flow of product and patients, but a straightforward dividing wall also gives patients privacy and direct one-on-one contact with a budtender to discuss medical issues. Many times, but not necessarily, your purchases will be tracked by medical dispensaries. This procedure can help budtenders and patients track effective medicine in addition to possess a living record of producers and products for future reference and follow-up. Medicinal dispensaries usually permit you to smell and analyze the buds before purchase. This might differ from state-to-state.
Yes, municipal approval is necessary prior to the AGLC will issue a retail cannabis license. Applicants should get in contact with their planned municipality to learn requirements regarding municipal retail cannabis legislation, zoning requirements, land-use limitations, and location requirements regarding how close a retail shop can be into a provincial medical care facility, college, or parcel of land designated as a college book.
